To use SNMP for monitoring Palo Alto Networks firewalls, Panorama, or WF-500 appliances, you must first load the Supported MIBs into your SNMP manager and determine which object identifiers (OIDs) correspond to the system statistics and traps you want to monitor. The following topics provide an overview of how to find OIDs and MIBs in an SNMP manager. For the specific steps to perform these tasks, refer to your SNMP management software.
Identify a MIB Containing a Known OID
If you already know the OID for a particular SNMP object (statistic or trap) and want to know the OIDs of similar objects so you can monitor them, you can explore the MIB that contains the known OID.
Identify a MIB Containing a Known OID
Load all the Supported MIBs into your SNMP manager.
Search the entire MIB tree for the known OID. The search result displays the MIB path for the OID, as well as information about the OID (for example, name, status, and description). You can then select other OIDs in the same MIB to see information about them.
Optionally, Walk a MIB to display all its objects.
Walk a MIB
If you want to see which SNMP objects (system statistics and traps) are available for monitoring, displaying all the objects of a particular MIB can be useful. To do this, load the Supported MIBs into your SNMP manager and perform a walk on the desired MIB. To list the traps that Palo Alto Networks firewalls, Panorama, and WF-500 appliance support, walk the panCommonEventEventsV2 MIB. In the following example, walking the PAN-COMMON-MIB.my displays the following list of OIDs and their values for certain statistics:
Identify the OID for a System Statistic or Trap
To use an SNMP manager for monitoring Palo Alto Networks firewalls, Panorama, or WF-500 appliances, you must know the OIDs of the system statistics and traps you want to monitor.
Identify the OID for a Statistic or Trap
Review the Supported MIBs to determine which one contains the type of statistic you want. For example, the PAN-COMMON-MIB.my contains hardware version information. The panCommonEventEventsV2 MIB contains all the traps that Palo Alto Networks firewalls, Panorama, and WF-500 appliances support.
Open the MIB in a text editor and perform a keyword search. For example, using Hardware version as a search string in PAN-COMMON-MIB identifies the panSysHwVersion object: panSysHwVersion OBJECT-TYPE SYNTAX DisplayString (SIZE(0..128)) MAX-ACCESS read-only STATUS current DESCRIPTION " Hardware version of the unit." ::= {panSys 2}
In a MIB browser, search the MIB tree for the identified object name to display its OID. For example, the panSysHwVersion object has an OID of 1.3.6.1.4.1.25461.2.1.2.1.2.
