Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The inventive concept of the embodiment of the application is as follows: in the prior art, index data acquisition needs to manually set a certain index and needs to use which OID to acquire, that is, the corresponding relationship between the acquisition index and the object identifier OID is determined, in practical application, a maintenance worker may not know the OID corresponding to the acquisition index, and at this time, the maintenance worker needs to consult an equipment manufacturer to find the OID corresponding to the acquired index from a lot of information. Therefore, the requirement on the professional technology of operation and maintenance personnel is high, and the index data acquisition efficiency is low due to the fact that manual work easily makes mistakes. In contrast, in the embodiment of the present application, on the basis of accumulating a large number of OID object identifiers corresponding to KPI indicators, a process of searching for an OID object identifier of an acquisition indicator is automatically completed. Compared with a manual setting searching mode, the error probability is much smaller, and the operation and maintenance labor cost is saved.
Fig. 1 is a flowchart of a performance index data acquisition method according to an embodiment of the present application, and referring to fig. 1, the performance index data acquisition method according to the embodiment includes the following steps:
step S101, acquiring information of performance indexes to be acquired of network equipment, and determining a first acquisition table corresponding to the performance indexes to be acquired according to historical acquisition records or corresponding relations between the performance indexes and object identifiers;
the first acquisition table comprises an object identifier of the performance index to be acquired;
step S102, based on the object identification of the performance index to be collected, a Simple Network Management Protocol (SNMP) collection interface is called to obtain index data of the performance index to be collected.
As shown in fig. 1, in the performance index data acquisition method of this embodiment, a first acquisition table corresponding to a performance index to be acquired is determined through a history acquisition record or a corresponding relationship between the performance index and an object identifier, and a Simple Network Management Protocol (SNMP) acquisition interface is called by the object identifier of the performance index to be acquired in the first acquisition table to obtain index data of the performance index to be acquired. Therefore, the performance index data acquisition process does not need manual participation, the labor cost of operation and maintenance is saved, and the error probability is reduced.
The following describes implementation steps of the performance index data acquisition method according to this embodiment with reference to a specific application scenario.
FIG. 2 is a schematic diagram of a process for determining a first acquisition table according to an embodiment of the present application, referring to FIG. 2, beginning with the process of importing an acquisition object; the incoming collection object is an index of the CPU utilization of a certain device (the IP address 192.168.1.1 of the device) for example. In practical application, a web display foreground or a third-party application issues a task according to a required acquisition object format by calling an external access interface provided by a network management system. When sending the collection object, the network management system obtains performance index information, such as a performance index set, including a CPU utilization rate, a memory utilization rate, and the like, through an interface.
Executing the step S201, inquiring manufacturer identification and model, and acquiring oid2kpi corresponding relation;
here, the oid2kpi correspondence represents the correspondence between oid (object id) and kpi (performance index), any managed resource in the SNMP system is represented as an object, oid is the object id, each performance index has its own object id, and the object id of each performance index is not unique.
The vendor identification is a unique identification of the manufacturer of the network device. The manufacturer of the network device may be different from manufacturer to manufacturer, such as the same router, the same arcade router, and the same cisco router. Network devices made by the same manufacturer may also vary in model, such as routers that are also Huacheng, and may be classified in model numbers 220 (for example only) and 230 (for example only). Therefore, when manually inquiring the performance index of a network device, the user needs to remember and input information such as a manufacturer and a model of the network device, then determines the performance index of the network device based on the information, obtains an object identifier of the performance index, and finally obtains performance index data by using the object identifier.
In this embodiment, system object identification information sysObjectID of the network device is collected based on the IP address of the network device, and vendor information and model information corresponding to the sysObjectID are obtained. After the manufacturer information and the model information of the network equipment to be collected are obtained, the corresponding relation between the performance index and the object identification can be obtained by searching a snmp oil 2kpi dictionary table according to the manufacturer information (such as Huashi), the model information (such as 230) and index information to be collected (such as CPU utilization rate). Therefore, the effects of automatically inquiring and acquiring the manufacturer and model information of the network equipment without manual input and memorization are achieved.
For example, standard oid (object identifier) Information of a general MIB (Management Information Base) is collected through an SNMP (Simple Network Management Protocol SNMP) collection interface 1.3.6.1.2.1.1.2, so that a sysObjectID of a Network device (such as the Network device with the aforementioned IP address 192.168.1.1) can be obtained, and corresponding vendor and model Information in a SNMP 2kpi dictionary table is searched through the sysObjectID. The snmp oid2kpi dictionary table is a complete set and contains oid2kpi corresponding relations corresponding to various types of manufacturers.
The implementation of the performance index data acquisition method of the embodiment is based on the SNMP, and the SNMP is briefly described here for easy understanding. SNMP is a standard protocol for managing network nodes (e.g., servers, workstations, routers, switches, etc.) in an IP network. The network managed by the SNMP mainly comprises three parts: managed devices, SNMP agents, Network Management Systems (NMS). Each device managed in the network has a management information base MIB for collecting and storing management information.
The network management system NMS can obtain this information via the SNMP protocol.
The managed devices, also referred to as network elements or network nodes, may be routers, switches, servers or hosts, etc. that support the SNMP protocol.
The SNMP agent is a network management software module on the managed device that holds the relevant management information of the local devices and serves to translate them into SNMP-compatible format to the NMS network management system.
The NMS network management system runs applications to implement the function of monitoring managed devices. The performance index data acquisition method of the embodiment of the application is applied to a Network Management System (NMS).
The method of this embodiment obtains information of performance indexes to be collected, and determines a first collection table corresponding to the performance indexes to be collected according to a historical collection record or a corresponding relationship between the performance indexes and object identifiers. Specifically, determining the first acquisition table corresponding to the performance index to be acquired according to the historical acquisition record or the corresponding relationship between the performance index and the object identifier includes: inquiring an acquisition record table in a database, and if the acquisition record table has a historical acquisition record of the performance index to be acquired, taking the acquisition table in the historical acquisition record as a first acquisition table corresponding to the performance index to be acquired; and if the historical acquisition record of the performance index to be acquired does not exist in the acquisition record table, determining a first acquisition table corresponding to the performance index to be acquired according to the corresponding relation between the performance index and the object identifier.
That is to say, in the embodiment of the present application, step S202 is executed to query the acquisition record table in the database, and the first acquisition table corresponding to the performance index to be acquired is determined only when there is no record of the performance index to be acquired in the acquisition record table, so that the steps can be simplified, and the acquisition efficiency can be improved.
Step S202, inquiring an acquisition record table;
in this step, the collection record table in the database is queried to determine whether the record of the index is collected before.
Step S203, whether a collection record exists or not; if yes, executing step S206, otherwise executing step S204;
in this step, it is determined whether there is a collection record of the performance index to be collected in the collection record table, if there is a record, step S206 is executed, and if there is no record, step S204 is executed.
Step S204, obtaining an acquisition table set according to the corresponding relation between the performance indexes and the object identifications;
since the judgment result in the previous step is that there is no acquisition record of the current performance index to be acquired in the acquisition record table, an acquisition table set is obtained in the current step according to the corresponding relationship between the performance index and the object identifier. Specifically, determining the first acquisition table corresponding to the performance index to be acquired according to the corresponding relationship between the performance index and the object identifier includes: acquiring system object identification information sysObjectID of the network equipment based on an IP address of the network equipment, acquiring manufacturer information and model information corresponding to the sysObjectID according to the sysObjectID, and acquiring a corresponding relation between a performance index and an object identification according to the manufacturer information and the model information; according to the corresponding relation between the performance indexes and the object identification, sequentially determining an acquisition table set corresponding to each performance index to be acquired, wherein the acquisition table set comprises at least one acquisition table; and taking the first acquisition table in each acquisition table set as the first acquisition table corresponding to the performance index to be acquired.
For example, all acquisition table tableids corresponding to kpiId of each performance index are queried from a snmp oil 2kpi dictionary table of the database based on the vendor information and the model information, and the tableids are placed in an acquisition table set, where the acquisition table set includes at least one acquisition table tableId. The kpiId represents an index identifier of an acquisition index, such as indexes of CPU utilization rate, memory utilization rate and the like; the tableId represents an acquisition table identifier, and the acquisition table is an MIB data table storing a corresponding relationship between a performance index (specifically kpiId) and an Object Identifier (OID).
The OID is an identifier of the MIB object provided by the SNMP, such as identifier OID {1.3.6.1.4.1} which is identifiers (vendors), and the number of nodes of the MIB object exceeds 3000. For example, Cisco, Inc. {1.3.6.1.4.1.9}, Noval Novell, Inc. {1.3.6.1.4.1.23}, and Cisco, Inc. {1.3.6.1.4.1.2011 }. Each manufacturer can define the name of the managed object of its own product, so that it can manage through SNMP.
In order to improve the acquisition efficiency, in practical application, the method of this embodiment supports multi-performance index acquisition, for example, 5 data acquisitions, which are respectively an index 1, an index 2, an index 3, an index 4, and an index 5, and then, when the method is applied, an acquisition table set corresponding to the index is sequentially determined from a first index.
Since the OID identifier corresponding to each performance index is not unique, taking the example that the index 1 is the CPU utilization rate, the OID identifiers of devices of different models of the same manufacturer may be different, for example, the OID identifier corresponding to the device of the model 320 is OID1, and the OID identifier corresponding to the device of the model 330 is OID2, when the index is acquired according to the IP address of the network device in the issued task, two OID identifiers may be obtained, and then two acquisition tables (one acquisition table only records the corresponding relationship between one OID and the KPI), such as table1 and table2, are obtained. In this embodiment, table1 and table2 are put into the collection table set of index 1 to obtain the collection table set of the CPU utilization index. By analogy, an acquisition table set with 5 indexes can be obtained. And then, taking the first acquisition table in each acquisition table set as the first acquisition table corresponding to the performance index to be acquired. Here, for example, the collection table identified as table1 is used as the first collection table corresponding to the CPU utilization index.
It should be noted that, after obtaining the corresponding relationship between the performance index and the object identifier from the manufacturer information and the model information, the embodiment screens the corresponding relationship between the performance index and the object identifier, because some object identifiers cannot acquire the required data when the object identifiers corresponding to the performance index are not unique, in order to ensure that the required data can be acquired, in the embodiment, multiple iterations are performed, and the first iteration directly uses the first acquisition table in each acquisition table set as the first acquisition table corresponding to the performance index to be acquired, so as to accelerate the iteration speed.
Step S205, merging to obtain a performance index set, and putting the table identifier of the first acquisition table and the performance index set into a cache;
after determining the first acquisition table corresponding to the performance index to be acquired, the method of this embodiment further includes: combining a plurality of performance indexes to be acquired corresponding to the same first acquisition table to obtain a performance index set to be acquired; storing the table identifier of the first acquisition table and the set of performance indexes to be acquired into a key-value pair set; the key value pair set comprises a plurality of key-value key value pairs, the key of each key-value key value pair is a table identifier of the first acquisition table, and the value is the set of performance indexes to be acquired.
As for 5 performance indexes, after the first acquisition tables are determined, since the first acquisition tables corresponding to each index may be the same, for example, the first acquisition table corresponding to index 1, the first acquisition table corresponding to index 3 is table1, the first acquisition table corresponding to index 2, the first acquisition table corresponding to index 4 and index 5 is table3, if the first acquisition table is sequentially read according to the first acquisition table corresponding to the index to obtain the OID object identifier, the first acquisition table needs to be read 5 times, in this embodiment, in order to improve efficiency, a scheme for merging the indexes is provided, and the specific merging step is: judging the first acquisition table corresponding to each performance index, if the table identification tables 1 of the first acquisition table corresponding to two performance indexes, such as index 1 and index 3, are the same, merging the two performance indexes to obtain a performance index set, such as { index 1 and index 3}, and then putting the performance index set { index 1 and index 3} and the table identification table1 of the first acquisition table corresponding to each performance index set into a cache together.
In order to increase the search speed, the embodiment stores the key-value key value pair mapping manner, that is, the table identifier of the first acquisition table is used as a key, the performance index set is used as a value to construct a key value pair, and the constructed key value pairs are used as elements and placed in the cached key value pair set.
Step S206, the table identifier and the performance index of the first acquisition table are put into a cache;
if data are collected for the current performance index to be collected before, the collection table in the collection record can be directly used as a first collection table of the performance index to be collected, and the table identifier of the first collection table and the current performance index to be collected are placed in the cache.
For example, if the index 5 is collected before, the collection table identifier is obtained according to the collection table of the index 5 in the history collection record, and the collection identifier and the identifier of the index 5 are placed in the cache together. Specifically, the index 5 can be put into a key-value pair set in the cache, and at this time, if the table identifier of the first acquisition table corresponding to the index 5 is matched with the key of any key-value pair of the existing key-value pairs in the key-value pair set, the index 5 can be put into the value of the matched key-value pair, so as to improve the acquisition efficiency,
and step S207, generating an acquisition task by the table identifier of the first acquisition table, and calling the thread in the thread pool for acquisition.
After the table identifier of the first acquisition table corresponding to each performance index is obtained, an acquisition task is generated according to the cached table identifier in this embodiment. In the above example, for table1, a collection task one is generated, a collection thread 1 in the thread pool is called to perform data collection, and for table3, a collection task two is generated, and a collection thread 2 in the thread pool is called to perform data collection. The performance index data collection process of this embodiment is shown in fig. 3,
after the acquisition thread is started, executing step S301 to acquire data for the first time;
specifically, the first data acquisition process includes: reading a key-value pair set to obtain a table identifier of the first acquisition table; determining a first acquisition table corresponding to the table identifier according to the table identifier of the first acquisition table, and obtaining the object identifier of each performance index to be acquired in the performance index set to be acquired from the first acquisition table corresponding to the table identifier; and calling a Simple Network Management Protocol (SNMP) acquisition interface based on the object identifier of each performance index to be acquired to obtain index data of the performance index to be acquired.
It should be noted that, the key point of this embodiment is how to determine the acquisition table corresponding to the performance index to be acquired and obtain the object identifier OID of the performance index to be acquired, and after obtaining the corresponding identifier OID, call the simple network management protocol SNMP acquisition interface, and obtain the index data of the performance index to be acquired by using the prior art means, therefore, details about the called SNMP acquisition interface and obtaining the performance index data through the SNMP acquisition interface may refer to the description of the prior art, and are not described herein again.
Step S302, whether data are collected or not is judged; if so, step S303 is executed, otherwise, step S304 is executed, and in practical applications, not every object identifier OID may obtain the required index data, so in this step, it is determined whether the index data can be acquired according to the object identifier in the first acquisition table, if the performance index data is acquired, step S303 is executed, and if the performance index data is not acquired, step S304 is executed.
Step S303, generating a collection record and storing the collection record into a database;
specifically, after the index data of the performance index to be collected is obtained, a collection record is generated based on the index identifier of the performance index to be collected, the index data, the table identifier of the collection table, and the collection time, and the collection record is stored in the collection record table in the database. For example, one collection record includes an index identifier kpiId, specific index data (e.g., CPU utilization rate 30%), a table identifier tableId of the collection table, and collection time xxxx.
Therefore, the collection records are put in storage, so that the performance index data of the same equipment can be conveniently collected next time, secondary analysis is not needed, and the data collection efficiency is improved.
Step S304, determining a second collection table set according to the corresponding relation between the performance index and the object identifier;
in this step, if the index data of the performance index to be acquired is not obtained, a second acquisition table corresponding to the performance index to be acquired is determined according to the corresponding relationship between the performance index and the object identifier.
It should be noted that, before determining the second acquisition table, the second acquisition table set is determined according to the corresponding relationship between the performance index and the object identifier, and the determination of the acquisition table set according to the corresponding relationship between the performance index and the object identifier is similar to the foregoing step S204, except that the second acquisition table set obtained in this step excludes the first acquisition table, in other words, the second acquisition table set obtained in this step does not include the first acquisition table, because it can be known from the foregoing description that performance index data is not acquired according to the first acquisition table, so when the second acquisition table is re-determined through secondary analysis, the first acquisition table is excluded to avoid waste of system resources.
S305, arranging the acquisition tables in a descending order according to the occurrence times of the acquisition tables, and determining a second acquisition table;
the method specifically comprises the following steps: according to the corresponding relation between the performance indexes and the object identification, sequentially determining a second acquisition table set corresponding to each performance index to be acquired, wherein the acquisition table set does not comprise a first acquisition table; counting the occurrence times of each acquisition table based on the second acquisition table set; and arranging the acquisition tables in the second acquisition table set in a descending order according to the occurrence frequency of the acquisition tables, and taking the acquisition table arranged at the first position as the second acquisition table.
For example, the indexes to be collected include an index a, an index B, an index C, a collection table set { table1, table2} corresponding to the index a, a collection table set { table1, table2, table3} corresponding to the index B, and a collection table set { table2, table4} corresponding to the index C. Counting the occurrence frequency of the acquisition table, wherein the available table1 occurs for 2 times, the table2 occurs for 3 times, and the table3 and the table4 each occur for 1 time, then after the acquisition tables in each second acquisition table set are sorted in a descending order according to the occurrence frequency, the acquisition table set { table2, table1} corresponding to the index A, the acquisition table set { table2, table1, table3} corresponding to the index B, and the acquisition table set { table2, table4} corresponding to the index C. Then, the second acquisition table corresponding to the index a is table2, the second acquisition table corresponding to the index B is also table2, and the second acquisition table corresponding to the index C is table 2. This results in a new key-value pair (table2, { index A, index B, index C }).
Step S306, collecting based on the table identification of the second collection table;
after the second acquisition table is obtained, based on the object identification of the performance index to be acquired in the second acquisition table, calling a Simple Network Management Protocol (SNMP) acquisition interface to obtain index data of the performance index to be acquired
Note: the acquisition in this step based on the table identifier of the second acquisition table is similar to the aforementioned step S301, except that the step S301 is to search for the object identifier OID of the performance index included in the first acquisition table based on the table identifier of the first acquisition table and perform acquisition based on the object identifier OID, and the step S301 is to perform acquisition based on the object identifier OID of the performance index included in the second acquisition table and perform acquisition based on the object identifier OID.
Step S307, whether data are acquired or not is judged, and if yes, step S303 is executed; otherwise, step S305 is performed.
Judging whether data are acquired or not in the step, if the data are acquired, returning to the step S303, namely generating an acquisition record to be stored, and if the data are not acquired, returning to the step S305 to re-determine the second acquisition table until each acquisition table in the acquisition table set corresponding to the performance index to be acquired is traversed once.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the objects so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in other sequences than described or illustrated herein.
As can be seen from the above, in the performance index data acquisition method of this embodiment, the information of the performance index to be acquired is acquired, the first acquisition table corresponding to the performance index to be acquired is determined according to the historical acquisition record or the corresponding relationship between the performance index and the object identifier, and the simple network management protocol SNMP acquisition interface is invoked based on the object identifier of the performance index to be acquired, so as to obtain the index data of the performance index to be acquired. Therefore, the performance index data acquisition process does not need manual participation, the operation and maintenance labor cost is saved, and the error probability is reduced.
