I have identified the SNMP OID for reading the Output Drops statistic for Cisco swithport interfaces. The final digit in this OID is the switchports ifIndex identifier.
Example: .184.108.40.206.220.127.116.11.1.19.7 .18.104.22.168.22.214.171.124.1.19. = OID for interface drops .7 = the specific interface I am querying for output drops.
What I want to be able to do is the following: 1) Save my custom SNMP OID Sensor with value of .126.96.36.199.188.8.131.52.1.19. such that it is an available selection in the Add Sensor Wizard. 2) When selecting my custom OID sensor, inside the Add Sensor Wizard, select each interface (switchport) I want this custom OID applied to. The result being the add sensor wizard would append the final ifIndex identifier to the OID, comleting the sensor config.
