    Hardware Health Polling - Preferred Cisco MIB


      Hi guys,


      Reviewing the Polling Settings page i found the Preferred Cisco MIB section for Hardware Health Polling.

      I know what this does but i'm not sure how it does it. What I need to know is what does the selection behave once changed and what effect the change has on Nodes being polled using one of the Preferred Cisco MIBs?


      Does changing the preferred MIB change globally, on all nodes or does it only change for nodes added AFTER the change?

          Hello Deltona,

          Each MIB provides access to different sensor data. Depending on the device 1 or both mibs may be supported.

          The Cisco SNMP object navigator is a useful reference.

          Cisco SNMP Object Navigator






          table name




          This table contains values for the entities, plus their type.

          CISCO-ENTITY-SENSOR-MIBentitySensorThresholdTable1. table contains thresholds for sensors
          ENTITY-MIBentPhysicalTable1. for chassis + each sensor name




          MIBtable nameOIDStatus OIDValue OID



          The setting can be applied globally or per node.


          For Global Changes

          1. Log on to web console
          2. Open Settings
          3. Open Polling Settings
          4. Look for section Hardware health Polling
          5. Change "Preferred Cisco MIB" setting to your preferred choice:
            1. CISCO-ENTITY-SENSOR-MIB (default) - usually good choice for newer models, some models might have very limited support of this MIB which results that very small amount of sensors is polled with this MIB
            2. CISCO-ENVMON-MIB - usually well supported by older devices, There is far less issues with this MIB, so in case both MIBs are supported and there is issue with CISCO-ENTITY-SENSOR-MIB, switching to this one.
          6. Submit changes



          For Per Node

          Per node setting overrides the global setting.

          It is possible to adjust the setting just for single node via Edit Node action on Management resource present on Node detail page.

          Node Management resource

          The same thing can be set for multiple nodes at once via Manage Nodes page with Edit Properties action (accessible from Settings page). See pictures below.


          Manage Nodes page

          Next steps are common:

          1. On the Edit Node properties page locate the Hardware Health Polling section
          2. Change the value:
            1. use global setting - will not use per node setting and instructs Orion to use the global setting for this node
            2. CISCO-ENTITY-SENSOR-MIB - instructs Orion to try polling sensors using the CISCO-ENTITY-SENSOR-MIB and ignore the global setting
            3. CISCO-ENVMON-MIB - instructs Orion to try polling sensors using the CISCO-ENVMON-MIB and ignore the global setting
          3. Submit changes.

            Hi, Tony, thanks for the info.


            Can you tell me in what table / field the selected MIB (CISCO-ENTITY-SENSOR-MIB or CISCO-ENVMON-MIB) in the Solarwinds database is being stored at ?

            We need that for our automated intake process.
