Step S2: and obtaining the specific information of the monitoring equipment according to the valid value of the OID data.
Step S3: and determining the equipment type of the monitoring equipment according to the specific information of the monitoring equipment.
Specifically, considering that different types of devices support different MIB libraries, such as an MIB-II (RFC-1213) library, a Bridge-MIB library, a Host-Resource-MIB library, and a Printer-MIB library, and the MIB library contains OID (object id, object identifier) data representing unique information of a device, the present application first obtains OID data representing unique information of a monitoring device in the MIB library of the monitoring device, and specifically obtains the OID data by accessing the MIB library of the monitoring device through an SNMP protocol (a TCP/IP protocol), and then, in a case that the OID data are obtained, can obtain the unique information of the monitoring device according to an effective value of the OID data representing the unique information of the device, so that the device type of the monitoring device can be determined according to the unique information of the monitoring device.
More specifically, when the OID data is acquired from the MIB, a plurality of OID data characterizing unique information of the device may be acquired to further improve accuracy of device type identification.
The invention provides a method for identifying equipment type, which comprises the steps of acquiring OID data representing the special information of monitoring equipment in an MIB (management information base) of the monitoring equipment; obtaining the specific information of the monitoring equipment according to the effective value of the OID data; and determining the equipment type of the monitoring equipment according to the specific information of the monitoring equipment. Therefore, the equipment type is not identified by acquiring the keyword of the sysDescr information in the MIB-II of the monitoring equipment, but by acquiring the OID data which represents the specific information of the equipment in the MIB library of the monitoring equipment, the equipment type identification method basically cannot generate equipment type identification errors, and the equipment type identification accuracy is improved.
On the basis of the above-described embodiment:
referring to fig. 2, fig. 2 is a specific flowchart of a method for identifying a device type according to an embodiment of the present invention.
As an optional embodiment, OID data characterizing specific information of the monitoring device in an MIB of the monitoring device is obtained; obtaining the specific information of the monitoring equipment according to the effective value of the OID data; the process of determining the device type of the monitoring device according to the unique information of the monitoring device includes:
acquiring data corresponding to a dedicated OID in a Bridge-MIB library of the monitoring equipment, and judging whether a return value obtained by acquiring the data is valid or not;
if yes, determining that the monitoring equipment is a switch;
if not, determining that the monitoring equipment is not the switch.
Specifically, this application judges whether supervisory equipment is the switch: considering that the Bridge-MIB is the specific MIB of the switch, the method first acquires data corresponding to the exclusive OID in the Bridge-MIB of the monitoring equipment, and judges whether a return value obtained by acquiring the data is effective; if the return value is valid, determining that the monitoring equipment is a switch; and if the return value is invalid, determining that the monitoring equipment is not the switch.
Such as: taking the special OID in the Bridge-MIB library: and if the number of ports is the node (.1.3.6.1.2.1.17.1.2.0), the path value (.1.3.6.1.2.1.17.2.6.0) from the current Bridge node to the root Bridge node, and the number of ports from the current Bridge node to the root Bridge node (.1.3.6.1.2.1.17.2.7.0), acquiring data of three OIDs, namely the node of the number of ports in the Bridge-MIB library of the monitoring equipment, the path value from the current Bridge node to the root Bridge node, and the number of ports from the current Bridge node to the root Bridge node, so as to judge whether the monitoring equipment is a switch.
As an optional embodiment, the identification method further includes:
after the monitoring equipment is determined not to be the switch, obtaining data of ipForwarding of an IP group in an MIB-II library of the monitoring equipment, and judging whether a return value obtained by obtaining the data is 1 or not;
if yes, determining the monitoring equipment as a router;
if not, determining that the monitoring equipment is not the router.
Further, the present application determines whether the monitoring device is a router: considering that the value of ipForwarding (.1.3.6.1.2.1.4.1) of an IP group in an MIB-II library of a router is 1, which indicates that the router has a forwarding function, but the forwarding function is not only a feature of the router, but also a feature of a part of switches (such as a three-layer switch), the method and the device obtain data of ipForwarding of the IP group in the MIB-II library of the monitoring device after determining that the monitoring device is not a switch, and determine whether a return value obtained by obtaining the data is 1; if the return value is valid, namely returning to '1', determining that the monitoring equipment is a router; and if the return value is invalid, determining that the monitoring equipment is not the router.
As an optional embodiment, the identification method further includes:
after the monitoring equipment is determined not to be the router, acquiring data corresponding to the exclusive OID in a Host-Resource-MIB base of the monitoring equipment, and judging whether a return value obtained by acquiring the data is valid or not;
if yes, determining the monitoring equipment as a server;
if not, determining that the monitoring equipment is not the server.
Further, the application judges whether the monitoring device is a server: considering that the Host-Resource-MIB is a specific MIB of the server, the method acquires data corresponding to the exclusive OID in the Host-Resource-MIB of the monitoring equipment after determining that the monitoring equipment is not the router, and judges whether a return value obtained by acquiring the data is valid; if the return value is valid, determining the monitoring equipment as a server; and if the return value is invalid, determining that the monitoring equipment is not the server.
Such as: taking a special OID in a Host-Resource-MIB library: and acquiring data of three OIDs (system operation time, system current time and system user number) in a Host-Resource-MIB library of the monitoring equipment to judge whether the monitoring equipment is a server or not (1.3.6.1.2.1.25.1.1.0), the system current time (1.3.6.1.2.1.25.1.2.0) and the system user number (1.3.6.1.2.1.25.1.5.0).
As an optional embodiment, the identification method further includes:
after the monitoring equipment is determined not to be the server, acquiring data corresponding to the exclusive OID in a Printer-MIB (identity information base) of the monitoring equipment, and judging whether a return value obtained by acquiring the data is valid or not;
if yes, determining that the monitoring equipment is a printer;
and if not, determining that the monitoring equipment is the monitoring equipment of the emergency type.
Further, this application judges whether supervisory equipment is the printer: considering that the Printer-MIB is the specific MIB of the server, the method acquires the data corresponding to the OID exclusively in the Printer-MIB of the monitoring equipment after determining that the monitoring equipment is not the server, and judges whether the return value acquired by the acquired data is valid; if the return value is valid, determining that the monitoring equipment is a printer; if the return value is invalid, the monitoring device is determined not to be a printer, that is, the monitoring device is determined to be an emergency type monitoring device. It should be noted that the devices are generally divided into common devices (switches, routers, servers, printers) and uncommon devices, and at present, the device type identification focuses on determining the types of the common devices.
Such as: taking special OID in Printer-MIB base: the current status of the Printer (.1.3.6.1.2.1.25.3.5.1.1.1), the control description of the Printer (.1.3.6.1.2.1.43.17.6.1.5), and the control color of the Printer (.1.3.6.1.2.1.43.17.6.1.4), data of three OIDs, i.e., the current status of the Printer, the control description of the Printer, and the control color of the Printer, in the Printer-MIB of the monitoring device are acquired to determine whether the monitoring device is a Printer.
As an optional embodiment, after acquiring data corresponding to an exclusive OID in a Printer-MIB database of the monitoring device, before determining whether a return value obtained by acquiring the data is valid, the identification method further includes:
the method comprises the steps of acquiring data of port number in an MIB (management information base) of monitoring equipment, and then judging whether a return value obtained by acquiring the data is effective or not.
Further, in the process of judging whether the monitoring device is a Printer, the method and the device not only acquire data corresponding to the exclusive OID in the Printer-MIB of the monitoring device, but also acquire data of the port number (.1.3.6.1.2.1.25.3.2.1.5.1) in the MIB of the monitoring device, and then judge whether return values obtained by acquiring the data are all valid; if the return values are all valid, determining that the monitoring equipment is a printer; and if the invalid return value exists, determining that the monitoring equipment is the monitoring equipment of the non-use type.
It should be noted that whether the return value is valid cannot be determined simply by whether there is a return value, because some SNMP messages return meaningless return values like "noSuchObject", and therefore it is necessary to determine whether the return value is valid by judging whether the return value is meaningful.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a system for identifying a device type according to an embodiment of the present invention.
The identification system of the device type comprises:
the system comprises a data acquisition module 1, a data processing module and a monitoring device, wherein the data acquisition module is used for acquiring OID data which is used for representing the specific information of the monitoring device in an MIB (management information base) of the monitoring device;
the information effective module 2 is used for obtaining the special information of the monitoring equipment according to the effective value of the OID data;
and the type determining module 3 is used for determining the equipment type of the monitoring equipment according to the specific information of the monitoring equipment.
