Using iReasoning to Add SNMP OID Information to Service Center

  • Last updated on

When you want to review what SNMP information a product exposes, whether to add to a predefined monitoring policy or build your own, you will need to perform an SNMP walk on the device. This is a process of querying the device with a GETNEXT statement to poll the entire hierarchy available, which is useful when you do not have access to the Management Information Base (MIB) file from the device vendor.

Freeware, such as iReasoning's MIB Browser application , can be used to perform an SNMP walk.

To perform an SNMP walk using iReasoning's MIB Browser application
  1. Launch iReasoning's MIB Browser software.
  2. From the Tools menu, select Options.
  3. Click the Default Values tab and enter the Agent Read Community
    This is the same as the Community String used by Onsite Managers, public, which is usually set by default and Agent SNMP Version. (Barracuda RMM supports version 1 and 2.)
  4. Click OK.
  5. Enter the IP for the device to which you want to connect in the Address box.
  6. From the OID list, select .1.3.
  7. From the Operations menu, select Walk.
  8. Click Go.
    Once the operation completes, you will see the entire MIB.
  9. Click the Name/OID.
    Reviewing the name and value often provides information as to what the purpose of the OID is. This will show the OID at the top in the OID box.
    For example, the default Lexmark Printer monitoring policy does not collect the device-reported system uptime. If you want to collect this value, you can locate the OID and follow the process listed below to make this OID available in Service Center.
To make the OID globally available in Service Center
  1. In Service Center, click Configuration > System Settings.
  2. Click the Network Objects tab.
  3. Under the SNMP OIDs section, click Add.
  4. Enter the Name from the iReasoning MIB Browser as the Object Name and enter the OID.
    Once this has been added, the OID will be globally available as a monitor to be used in a monitoring policy or device level monitor.
