SNMP Polling​

This dashboard is a search for NFO output from SNMP Custom OID Sets Monitor. For more information on this Module, visit SNMP Custom OID Sets Monitor.

SNMP Traps​

This dashboard is a search for NFO output of SNMP Traps.

Interface Errors and Discards​

This dashboard provides network device health statistics based on interface errors and discards counts, as depicted below:

It relies on events sent to Splunk by NFO SNMP Custom OID Sets Monitor Module fields defined in interface_mon OID set. This dashboard utilizes the following lookup files:

  1. snmp-devices.csv
  2. critical_interfaces.csv

The snmp-devices.csv file is populated by a saved search that runs every 30 minutes. You can trigger this search on the setup page by clicking the "update dropdowns" button.

To utilize the "Show non-critical interfaces" toggle, ensure the critical_interfaces.csv lookup file is set up correctly. Below is a sample of the critical_interfaces.csv lookup file:

nfo_hostname,"management_ip","snmp_index","comment"
localhost","10.0.3.2",1,"Important interface"
localhost",10.0.5.22,116,"Uplink"

SNMP Devices CPU and Memory​

This dashboard provides network device health based on CPU and memory utilization, as depicted below:

It relies on events sent to Splunk by NFO SNMP Custom OID Sets Monitor Module. The following fields should be defined in this Module OID sets:

  • For CPU utilization: cpu_load_percent

  • For memory utilization: either mem_used_percent or any two of the following OIDs: mem_used, mem_free, or mem_total

For more information, see SNMP Custom OID Sets Monitor section in Getting Started Guide: SNMP Polling.
