Detailed Description
In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings. It will be apparent that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The inventive concept of the embodiment of the application is as follows: in the prior art, the index data acquisition needs to manually set a certain index and needs to use which OID to acquire, namely, the corresponding relation between the acquired index and the object identifier OID is determined, in practical application, there may be a case that a maintainer does not know the OID corresponding to the acquired index, then he needs to consult a manufacturer of equipment, and find the OID identifier corresponding to the acquired index from a plurality of information. Therefore, the special technical requirements on operation and maintenance personnel are high, and index data acquisition efficiency is low because of the fact that mistakes are easy to occur manually. In this regard, the embodiment of the present application automatically completes the process of searching the OID object identifiers of the acquisition indicators on the basis of accumulating the OID object identifiers corresponding to a large number of KPI indicators. Compared with a manual setting searching mode, the method has the advantages that 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, referring to fig. 1, the performance index data acquisition method of the present 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 a historical acquisition record or a corresponding relation between the performance indexes and object identifiers;
the first acquisition table comprises object identifiers of the performance indexes to be acquired;
step S102, based on the object identification of the performance index to be acquired, a simple network management protocol SNMP acquisition interface is called to obtain index data of the performance index to be acquired.
As can be seen from fig. 1, in the performance index data collection method of this embodiment, a first collection table corresponding to the performance index to be collected is determined according to a history collection record or a correspondence between the performance index and an object identifier, and the object identifier of the performance index to be collected in the first collection table invokes a simple network management protocol SNMP collection interface to obtain index data of the performance index to be collected. Therefore, the performance index data acquisition process does not need to be manually participated, the labor cost of operation and maintenance is saved, and the error probability is reduced.
The implementation steps of the performance index data acquisition method of the present embodiment are described below with reference to a specific application scenario.
FIG. 2 is a schematic flow chart of determining a first acquisition table according to one embodiment of the present application, see FIG. 2, and the flow begins with an incoming acquisition object; here, the incoming acquisition object is an index of CPU utilization of an apparatus (IP address 192.168.1.1 of the apparatus) for acquisition. In practical application, the web shows a foreground or a third party application, and performs task issuing according to a required acquisition object format by calling an external access interface provided by a network management system. When issuing the acquisition object, the network management system acquires performance index information, such as a performance index set, including CPU utilization rate, memory utilization rate and the like, through an interface.
Step S201 is executed, the manufacturer identification and model are inquired, and the corresponding relation of oid2kpi is obtained;
the oid-kpi correspondence here represents the correspondence between oid (object identifier) and kpi (performance index), any managed resource in the SNMP system is represented as an object, oid is an object identifier, each performance index has its own object identifier, and the object identifier of each performance index is not unique.
The vendor identification is a unique identification of the manufacturer of the network device. The manufacturer is different, and the manufacturer identification of the network device is different, such as the same router, the Huacheng router and the Cisco router are different. The network devices produced by the same manufacturer are also distinguished by model numbers, such as routers, which are also denoted by the name "Hua," and can be classified into 220 (by way of example only) and 230 (by way of example only). Therefore, when the performance index of a network device is manually inquired, the information of the manufacturer, the model and the like of the network device is needed to be memorized and input, then the performance index of the network device is determined based on the information, the object identification of the performance index is obtained, and finally the performance index data is obtained by utilizing the object identification.
In this embodiment, based on the IP address of the network device, the system object identification information sysObjectID of the network device is collected, and vendor information and model information corresponding to the sysObjectID are obtained. After manufacturer information and model information of the network equipment to be acquired are obtained, the corresponding relation between the performance index and the object identifier can be obtained by searching a snmpoid2kpi dictionary table according to the manufacturer information (such as Hua Cheng), the model information (such as 230) and the index information to be acquired (such as CPU utilization rate). Therefore, the automatic inquiry and acquisition of the manufacturer and model information of the network equipment are realized, and the effects of manual input and identification are not required.
For example, standard OID (Object Identifier) information of a common MIB (Management Information Base ) is collected through an SNMP (Simple Network Management Protocol, simple network management protocol SNMP) collection interface 1.3.6.1.2.1.1.2, and a sysObjectID of a network device (such as the aforementioned network device with an IP address of 192.168.1.1) can be obtained, and manufacturer and model information corresponding to the snmpoid2kpi dictionary table is searched through the sysObjectID. The snmpoid2kpi dictionary table is a complete set and contains oid2kpi corresponding relations corresponding to various types of manufacturers.
The implementation of the performance index data collection method of the present embodiment is based on SNMP, and a brief description of SNMP is provided herein for ease of 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 SNMP is mainly composed of three parts: managed devices, SNMP agents, network management systems (NMS, network Management System). Each device managed in the network has a management information base MIB for collecting and storing management information.
Through the SNMP protocol, the network management system NMS can obtain this information.
The managed devices, also called network elements or network nodes, may be routers, switches, servers or hosts, etc. supporting the SNMP protocol.
The SNMP agent is a network management software module on the managed device that has the relevant management information of the local device and is used to convert them into a SNMP-compatible format for delivery to the NMS network management system.
The NMS network management system runs applications to implement the function of monitoring the managed devices. The performance index data acquisition method is applied to the NMS.
According to the method, information of the performance index to be acquired is acquired, and a first acquisition table corresponding to the performance index to be acquired is determined according to a historical acquisition record or a corresponding relation between the performance index and an object identifier. Specifically, according to the corresponding relation between the historical acquisition record or the performance index and the object identifier, determining the first acquisition table corresponding to the performance index to be acquired includes: inquiring an acquisition record table in a database, and taking the acquisition table in the history acquisition record as a first acquisition table corresponding to the performance index to be acquired if the history acquisition record of the performance index to be acquired exists in the acquisition record table; 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, in the embodiment of the present application, step S202 is executed first to query the collection record table in the database, and the first collection table corresponding to the performance index to be collected is determined only when there is no record of the performance index to be collected in the collection record table, so that the steps can be simplified, and the collection efficiency can be improved.
Step S202, inquiring an acquisition record table;
in this step, the collection record list in the database is queried to determine whether the record of the index is collected before.
Step S203, whether an acquisition record exists; if yes, go to step S206, otherwise go to step S204;
in this step, it is determined whether there is an acquisition record of the performance index to be acquired in the acquisition record table, if so, step S206 is executed, and if not, step S204 is executed.
Step S204, obtaining an acquisition table set according to the corresponding relation between the performance index and the object identifier;
since the judgment result in the previous step is that the acquisition record table has no acquisition record of the current performance index to be acquired, the acquisition table set is obtained according to the corresponding relation between the performance index and the object identifier in the previous step. Specifically, according to the corresponding relation between the performance index and the object identifier, determining the first acquisition table corresponding to the performance index to be acquired includes: acquiring system object identification information sysObjectID of the network equipment based on the IP address of the network equipment, acquiring manufacturer information and model information corresponding to the sysObjectID according to the sysObjectID, and acquiring the 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 identifiers, sequentially determining acquisition table sets corresponding to the performance indexes to be acquired, wherein each acquisition table set comprises at least one acquisition table; and taking the first acquisition table in each acquisition table set as a first acquisition table corresponding to the performance index to be acquired.
For example, querying all acquisition tables tabld corresponding to kpiId of each performance index from a snmpoid2kpi dictionary table of a database based on the vendor information and the model information, and placing the tabld into an acquisition table set, wherein the acquisition table set comprises at least one acquisition table tabld. The kpiId here represents index identification of the 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 correspondence relationship between performance indexes (specifically kpiId) and Object Identifiers (OIDs).
The OID here is an identifier of MIB objects provided by SNMP, such as identifier OID {1.3.6.1.4.1}, i.e. entries, and the number of nodes to which the OID belongs exceeds 3000. For example, {1.3.6.1.4.1.9}, nowil Novell, cisco, {1.3.6.1.4.1.23}, hua, {1.3.6.1.4.1.2011}. Each vendor can define the managed object name of its own product so that it can be managed through SNMP.
In order to improve the acquisition efficiency, in practical application, the method of the embodiment supports multi-performance index acquisition, for example, 5 data acquisition of index 1, index 2, index 3, index 4 and index 5 are respectively performed, and then the acquisition table set corresponding to the index is sequentially determined from the first index during application.
Since the OID identifiers corresponding to the performance indexes are not unique, taking the CPU utilization as an example, the OID identifiers of different types of equipment of the same manufacturer may be different, for example, the OID identifier corresponding to the equipment with model 320 is OID1, the OID identifier corresponding to the equipment with model 330 is OID2, and then when the index of the CPU utilization is collected according to the IP address of the network equipment in the issuing task, two OID identifiers may be obtained, and further two collection tables (one collection table only records the corresponding relationship between one type of OID and KPI), for example, table1 and table2 may be obtained. In this embodiment, table1 and table2 are put into the collection table set of index 1, so as to obtain the collection table set of CPU utilization index. Similarly, a collection of 5 index acquisition tables can be obtained. And then, taking the first acquisition table in each acquisition table set as a first acquisition table corresponding to the performance index to be acquired. Here, for example, an acquisition table whose table is identified as table1 is used as the first acquisition table corresponding to the CPU utilization index.
It should be noted that, after the correspondence between the performance index and the object identifier is obtained from the vendor information and the model information, the embodiment screens the correspondence between the performance index and the object identifier, because when the object identifier corresponding to the performance index is not unique, some object identifiers cannot collect the required data, so in order to ensure that the required data can be collected, in this embodiment, multiple iterations are performed, and the first round directly uses the first collection table in each collection table set as the first collection table corresponding to the performance index to be collected, so as to accelerate the iteration speed.
Step S205, merging to obtain a performance index set, and putting the table identification of the first acquisition table into a cache;
after determining the first acquisition table corresponding to the performance index to be acquired, the method of the embodiment further includes: combining a plurality of to-be-acquired performance indexes corresponding to the same first acquisition table to obtain a to-be-acquired performance index set; storing the table identifier of the first acquisition table and the to-be-acquired performance index set into a key value pair set; the key-value pair set comprises a plurality of key-value pairs, wherein key keys of the key-value pairs are table identifiers of the first acquisition table, and value is the performance index set to be acquired.
For the above example, after determining the first acquisition table for the 5 performance indexes, since the first acquisition tables corresponding to the indexes may be the same, for example, the first acquisition table corresponding to the index 1, the first acquisition table corresponding to the index 3 is table1, the index 2, the first acquisition tables corresponding to the index 4 and the index 5 are table3, if the first acquisition tables are sequentially read according to the first acquisition table corresponding to the index to obtain the OID object identifier, then the first acquisition tables need to be read for 5 times, in this embodiment, in order to improve the efficiency, a scheme for merging the indexes is provided, and the specific merging steps are as follows: judging the first acquisition table corresponding to each performance index, if the table identifiers table1 of the first acquisition table corresponding to the two performance indexes such as index 1 and index 3 are the same, combining 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 identifier table1 of the first acquisition table corresponding to each performance index set into a cache together.
In order to improve the searching speed, the method of key-value key pair mapping is adopted for storage in this embodiment, that is, the table identifier of the first collection table is used as a key, the performance index set is used as a value to construct key pairs, the constructed key pairs are used as elements to be put into the cached key pair set, and it can be understood that the elements in the key pair set are key pairs.
Step S206, the table identification of the first acquisition table and the performance index are put into a cache;
if the current performance index to be acquired is acquired, the acquisition table in the acquisition record can be directly used as a first acquisition table of the performance index to be acquired, and the table identifier of the first acquisition table and the current performance index to be acquired are put into a cache.
For example, if the index 5 is collected before, according to the collection table of the index 5 in the history collection record, the collection table identifier is obtained, and the collection identifier and the identifier of the index 5 are put into the cache together. In particular, the index 5 can be put into the value of any key value pair in the existing key value pair in the key value pair set if the table identifier of the first acquisition table corresponding to the index 5 is matched with the key of the key value pair, so as to improve the acquisition efficiency,
Step S207, generating an acquisition task by the table identification of the first acquisition table, and calling the threads in the thread pool for acquisition.
After obtaining the table identifier of the first acquisition table corresponding to each performance index, in this embodiment, an acquisition task is generated according to the cached table identifier. For the example, generating the first acquisition task for the table1, calling the acquisition thread 1 in the thread pool to acquire data, generating the second acquisition task for the table3, and calling the acquisition thread 2 in the thread pool to acquire data. The flow of collection of performance index data of this embodiment is shown in figure 3,
after the acquisition thread is started, step S301 is executed 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 object identifiers of all the performance indexes 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 identification of each performance index to be acquired to obtain index data of the performance index to be acquired.
It should be noted that, in this embodiment, how to determine the collection table corresponding to the performance index to be collected and obtain the object identifier OID of the performance index to be collected, and call the SNMP collection interface of the simple network management protocol after obtaining the corresponding identifier OID, so that the index data of the performance index to be collected may be implemented by using the prior art means, so details about the called SNMP collection interface and obtaining the performance index data through the SNMP collection interface may be referred to the description of the prior art, and are not repeated herein.
Step S302, whether data are acquired or not; if yes, step S303 is executed, otherwise step S304 is executed, in practical application, not every object identifier OID can obtain the required index data, so in this step, it is determined whether the index data can be collected according to the object identifier in the first collection table, if the performance index data is collected, step S303 is executed, and if the performance index data is not collected, step S304 is executed.
Step S303, generating an acquisition record and storing the acquisition record in a database;
specifically, after index data of the performance index to be acquired is obtained, an acquisition record is generated based on the index identifier of the performance index to be acquired, the index data, the table identifier of the acquisition table and the acquisition time, and the acquisition record is stored in an acquisition record table in a 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 a collection table, and a collection time xxxx.
Therefore, by warehousing the acquisition record, the next acquisition of the performance index data of the same equipment is facilitated, secondary analysis is not needed, and the data acquisition efficiency is improved.
Step S304, determining a second collection table set through the corresponding relation between the performance index and the object identifier;
in the step, if the index data of the performance index to be acquired is not obtained, determining a second acquisition table corresponding to the performance index to be acquired according to the corresponding relation 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 correspondence between the performance index and the object identifier, and the acquisition table set is determined according to the correspondence between the performance index and the object identifier, which is similar to the step S204, except that the first acquisition table is excluded from the second acquisition table set obtained in this step, in other words, the second acquisition table set obtained in this step does not include the first acquisition table, because it is known from the foregoing description that the performance index data is not acquired according to the first acquisition table, when the second acquisition table is redetermined by performing the secondary analysis, the first acquisition table is excluded from the second acquisition table, so as to avoid the waste of system resources.
Step S305, arranging the acquisition tables in 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 identifiers, 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 sets in a descending order according to the occurrence times of the acquisition tables, and taking the acquisition table arranged at the first position as a second acquisition table.
For example, the to-be-acquired indexes include an index a, an index B, an index C, an acquisition table set { table1, table2} corresponding to the index a, an acquisition table set { table1, table2, table3} corresponding to the index B, and an acquisition table set { table2, table4} corresponding to the index C. Counting the occurrence times of the acquisition tables to obtain 2 times of occurrence of table1, 3 times of occurrence of table2, 1 time of occurrence of each of table3 and table4, and arranging acquisition table sets { table2, table1} corresponding to the index A, acquisition table sets { table2, table1, table3} corresponding to the index B, and acquisition table sets { table2, table4} corresponding to the index C in descending order of the acquisition tables in each second acquisition table set according to the occurrence times. Then, the second acquisition table corresponding to the index a is table2, the second acquisition table corresponding to the index B is table2, and the second acquisition table corresponding to the index C is table2. Thus, a new key value pair (table 2, { pointer a, pointer B, pointer C }) is obtained.
Step S306, collecting based on the table identification of the second collection table;
after the second acquisition table is obtained, calling a simple network management protocol SNMP acquisition interface based on the object identification of the performance index to be acquired in the second acquisition table to obtain index data of the performance index to be acquired
Note that: the step of collecting based on the table identifier of the second collection table is similar to the step S301, in which the step S301 is to search for the object identifier OID of the performance index included in the first collection table based on the table identifier of the first collection table and collect based on the object identifier OID, and the step is to collect based on the object identifier OID of the performance index included in the second collection table and collect based on the object identifier OID.
Step S307, if data is collected, executing step S303; otherwise, step S305 is performed.
In this step, it is determined whether data is collected, if data is collected, the step S303 is executed again, that is, the collection record is generated and put in storage, and if data is not collected, the step S305 is executed again until each collection table in the collection table set corresponding to the performance index to be collected is traversed once.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the objects so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in other sequences than those illustrated or otherwise described herein.
As can be seen from the above, in the method for acquiring performance index data of the present embodiment, by acquiring information of a performance index to be acquired, according to a history acquisition record or a correspondence between the performance index and an object identifier, a first acquisition table corresponding to the performance index to be acquired is determined, and based on the object identifier of the performance index to be acquired, a simple network management protocol SNMP acquisition interface is invoked to obtain the index data of the performance index to be acquired. Therefore, the performance index data acquisition process does not need to be manually participated, the operation and maintenance labor cost is saved, and the error probability is reduced.
