This article provides the information to create the UnDP and alert to monitor the Cisco Nexus Platform Components (e.g. Ethernet Module, Fabric Module, etc.) by using the OIDs below:

• MIB	table name	OID	Description
  CISCO-ENTITY-FRU-CONTROL-MIB	cefcModuleOperStatus	1.3.6.1.4.1.9.9.117.1.2.1.1.2	This object shows the module's operational state.
  ENTITY-MIB	entPhysicalTable	1.3.6.1.2.1.47.1.1.1	Description for chassis + each sensor

Network Performance Monitor

n/a

1. Create UnDP using the OIDs below:

   • table name	OID
     cefcModuleOperStatus	1.3.6.1.4.1.9.9.117.1.2.1.1.2
     entPhysicalTable	1.3.6.1.2.1.47.1.1.1

2. For the UnDP of cefcModuleOperStatus, perform the steps below to map the value for the status:
   • Expand "Show Advanced Options" and select Enumeration from "Format":
     • 
   • Click "Map Values", enter the Raw and Text value accordingly. (Refer this link for the status values) 
     • 
3. Select the UnDP label as below:
   • UnDP cefcModuleOperStatus 
     • 
   • UnDP entPhysicalTable
     • 
4. On the target Node Details page, add "Node Tabular Universal Device Poller" widget, edit and set the settings as below:
   • 
   • Result as below:
     • 
5. Create new custom table poller alert, trigger condition as below:
   • 
6. Due to the alert is based on the UnDP for the cefcModuleOperStatus, the alert variable for the module name will need to use SQL query to get from the UnDP for entPhysicalDescr. Alert variable as below:
   • ${SQL: SELECT CPS.Label FROM CustomPollerStatusTable as CPS
     Right JOIN CustomPollerAssignment AS CPA ON CPS.NodeID = CPA.NodeID
     WHERE CPs.CustomPollerAssignmentID != '${N=SwisEntity;M=CustomPollerAssignment.CustomPollerAssignmentID}'
     AND CPA.AssignmentName LIKE '%entPhysicalDescr%'
     AND CPA.NodeID = '${N=SwisEntity;M=CustomPollerAssignment.Node.NodeID}'
     AND CPS.RowID = '${N=SwisEntity;M=RowID}'}
7. Example for the alert message:
   • ${SQL: SELECT CPS.Label FROM CustomPollerStatusTable as CPS
     Right JOIN CustomPollerAssignment AS CPA ON CPS.NodeID = CPA.NodeID
     WHERE CPs.CustomPollerAssignmentID != '${N=SwisEntity;M=CustomPollerAssignment.CustomPollerAssignmentID}'
     AND CPA.AssignmentName LIKE '%entPhysicalDescr%'
     AND CPA.NodeID = '${N=SwisEntity;M=CustomPollerAssignment.Node.NodeID}'
     AND CPS.RowID = '${N=SwisEntity;M=RowID}'} Status is ${N=SwisEntity;M=Status}
   • Result as below:
     •
