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 invention.
Fig. 1 is a flowchart of a SNMP-based network device maintenance method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
step S01, if the device to be identified is determined to meet the preset discovery rule, obtaining a mapping rule corresponding to the device to be identified; and the discovery rules are in one-to-one correspondence with the mapping rules.
The embodiment of the invention provides a method for identifying equipment to be identified in a Network and acquiring attribute information of attributes of the equipment by using a Simple Network Management Protocol (SNMP) and an Object Identifier (also called an Internet of things Identifier (OID)).
The monitoring server establishes a one-to-one correspondence relationship between the attributes and the object identifiers in advance, for example, as shown in table 1 below:
TABLE 1 Attribute to object identifier Table
The monitoring server classifies the devices according to the characteristics of the devices in the network, and sets mapping rules and discovery rules corresponding to the types of the devices one by one in advance, and thus, the mapping rules and the discovery rules are also corresponding one by one.
The mapping rules specify the number and type of specific attributes contained by the device corresponding to the device type, and an object identifier corresponding to each attribute, referred to herein as a first object identifier.
And the corresponding discovery rule is used to determine the device type to which the device belongs.
When the monitoring server acquires the device to be identified in the network, the preset discovery rules can be respectively matched with the monitored device to be identified so as to judge whether the device to be identified meets a certain discovery rule:
if the device type is not satisfied, judging that the device to be identified belongs to a device type which cannot be identified by the monitoring server;
if the device to be identified meets a certain discovery rule, the device to be identified can be determined to belong to the device type corresponding to the discovery rule, and the mapping rule corresponding to the device to be identified is obtained according to the one-to-one correspondence relationship between the discovery rule and the mapping rule.
Step S02, according to the first object identifier included in the mapping rule, acquiring attribute information of an attribute corresponding to the first object identifier from the device to be identified.
The monitoring server extracts a first object identifier contained in the mapping rule corresponding to the device to be identified, and tries to acquire attribute information of an attribute of the device to be identified, wherein the attribute corresponds to the first object identifier. Specifically, the monitoring server may send an information obtaining instruction including a first object identifier to the device to be identified, so that the device to be identified replies attribute information of an attribute corresponding to the first object identifier.
Then, the current operation condition of the equipment to be identified can be obtained by analyzing the received attribute information, so as to judge whether a fault is likely to occur, eliminate hidden dangers in time, prevent the occurrence of the fault, and dispose the fault which has occurred in time.
The embodiment of the invention determines the equipment type of the equipment to be identified according to the preset one-to-one corresponding relation between the discovery rule and the mapping rule by the discovery rule, and then obtains the attribute information of each attribute in the equipment to be identified according to the object identifier in the corresponding mapping rule, thereby simply and quickly realizing the identification of the equipment to be identified and the collection of the attribute information.
Fig. 2 is a flowchart of another SNMP-based network device maintenance method according to an embodiment of the present invention, and as shown in fig. 2, the step S01 specifically includes:
step S011, obtaining attribute information of an attribute corresponding to the second object identifier from the device to be identified according to the second object identifier included in the discovery rule and expectation information corresponding to the second object identifier, and matching the attribute information with the corresponding expectation information.
The discovery rule for identifying the device type of the device to be identified may be set according to actual needs, for example, the discovery rule may be determined by identifying specific data information transmitted by the device to be identified in a network, or may be determined by a specific device identifier of the device to be identified.
The embodiment of the invention only gives an illustration of one of the embodiments.
According to the difference of the attributes contained in the devices of different device types and the difference of the selectable ranges of the corresponding attribute information, at least one object identifier, referred to as a second object identifier, and expectation information corresponding to the second object identifier are set in the corresponding discovery rule, wherein the expectation information is used for characterizing the information selection range.
And if the discovery rule is matched with the equipment to be identified, sending a second object identifier in the discovery rule to the equipment to be identified so as to obtain attribute information of the attribute corresponding to the second object identifier. The attribute information is then matched with the corresponding expectation information.
Step S012, if the acquired attribute information of the device to be identified matches the corresponding expected information, determining that the device to be identified satisfies the discovery rule.
If the obtained matching result shows that the obtained attribute information is matched with the corresponding expected information, the device to be identified can be judged to meet the discovery rule, namely the device to be identified belongs to the device type corresponding to the discovery rule.
Further, after the step S011, the method further includes:
step S0121, if the device to be identified does not have the attribute corresponding to the second object identifier, or the obtained attribute information is not matched with the corresponding expected information, determining that the device to be identified does not meet the discovery rule.
If the monitoring server does not receive the attribute information of the attribute corresponding to the device to be identified and the second object identifier, or the obtained attribute information is not matched with the corresponding expected information, that is, the obtained attribute information exceeds the information selection range represented by the expected information, it can be determined that the device to be identified does not meet the discovery rule.
Examples are as follows:
the monitoring server classifies the devices into three device types: a1, a2, A3; respectively corresponding to the discovery rules: b1, B2, B3, mapping rules: c1, C2, C3; the discovery rule B1 includes a second object identifier d1, d2 and corresponding expectation information e1, e2, respectively; the discovery rule B2 includes a second object identifier d1, d3 and corresponding expectation information e1, e3, respectively; the discovery rule B3 includes a second object identifier d2, d4 and corresponding expectation information e2, e4, respectively; the mapping rule C1 includes first object identifiers d1, d2, d5, d 6; the mapping rule C2 includes first object identifiers d1, d3, d5, d 6; the mapping rule C3 includes first object identifiers d2, d4, d5, d 6.
When the device to be identified X is monitored, matching the discovery rules B1, B2 and B3 with the device to be identified X respectively, wherein the obtained matching results are respectively as follows: the attribute information corresponding to d1 in X is s1, s1 is matched with e1, and X does not include the attribute information corresponding to d 2; attribute information corresponding to d1 in X is s1, and s1 matches e1, attribute information corresponding to d3 in X is s3, and s1 matches e 3; x does not include attribute information corresponding to d2, and X does not include attribute information corresponding to d 2. It can be seen that X satisfies the discovery rule B2, which corresponds to the mapping rule C2, and thus, X includes attribute information corresponding to the first object identifiers d1, d3, d5, d 6.
And S013, determining the mapping rule corresponding to the equipment to be identified according to the one-to-one correspondence relationship between the discovery rule and the mapping rule.
After the discovery rule satisfied by the device to be identified is determined, so as to obtain the device type to which the device to be identified belongs, the mapping rule corresponding to the device to be identified can be further determined according to the one-to-one correspondence relationship between the discovery rule and the mapping rule.
According to the embodiment of the invention, the second object identifier and the corresponding expectation information are set in the discovery rule, and the attribute information and the expectation information corresponding to the device to be identified and the second object identifier are matched, so that the discovery rule met by the device to be identified can be simply and quickly determined, and the mapping rule corresponding to the discovery rule is further determined.
Based on the above embodiment, further, after the step S012, the method further includes:
and obtaining the manufacturing information of the equipment to be identified according to the matching result of each attribute information and the corresponding expectation information.
In the process of judging the discovery rule satisfied by the device to be identified, the obtained attribute information is matched with the corresponding expected information, so that the manufacturing information of the device to be identified, such as a manufacturer, a model and the like, can be further obtained.
According to the embodiment of the invention, the manufacturing information of the equipment to be identified is obtained through the matching result of each attribute information and the corresponding expectation information, so that the equipment to be identified can be identified in more detail.
Based on the foregoing embodiment, further, the determining that the device to be identified meets the preset discovery rule specifically includes:
and sequentially judging whether the equipment to be identified meets the discovery rules or not according to the preset priority of each discovery rule until the discovery rules met by the equipment to be identified are determined.
In the process of matching each discovery rule with the device to be identified, in order to enable the whole matching process to be more reasonable and ordered, the priority of each discovery rule device can be correspondingly prioritized. And after the equipment to be identified is determined not to meet the current discovery rule, calling the next discovery rule to execute the matching process until the equipment to be identified is determined to meet the current discovery rule, and terminating the matching process.
The priority may be divided according to important programs of the corresponding device type, or occupancy among all devices in the network, and the like, and is not particularly limited herein.
According to the embodiment of the invention, the matching process of the discovery rule and the equipment to be identified is more reasonable and ordered by the preset priority of the discovery rule, and the identification speed of the equipment to be identified is accelerated.
Based on the above embodiment, further, before the step S01, the method further includes:
and step S00, obtaining the equipment to be identified by scanning a preset IP address range.

Further, after the step S00, the method further includes:
and S001, logging in the equipment to be identified according to a preset SNMP certificate corresponding to the SNMP version.
In the process of scanning the IP addresses one by one, if a certain IP address is determined to be connected with the equipment to be identified, the equipment to be identified is tried to be logged in according to a preset SNMP certificate corresponding to the SNMP version. If the login is successful, the connection of the equipment to be identified is judged to be normal, otherwise, the connection of the equipment to be identified is judged to be abnormal, and the subsequent identification process cannot be executed.
The embodiment of the invention obtains the equipment to be identified by scanning the preset IP address range and logs in according to the preset SNMP certificate, thereby ensuring that the equipment to be identified can be quickly identified.
Based on the above embodiment, further, the first object identifier and the second object identifier are specifically: a numerical form of a single numerical value, or a tabular form of a plurality of numerical values.
The object identifiers corresponding to the attributes, including the first object identifier in the mapping rule and the second object identifier in the discovery rule, may be set according to actual needs, and may be set in a numerical form composed of a single numerical value as shown in table 1, that is, set as a leaf node; or a table form composed of a plurality of values, that is, a table node is set, and the attribute corresponds to each value in the table.
According to the embodiment of the invention, the object identifiers are set as leaf nodes or table nodes, so that the device types can be more reasonably divided.
