Details of User Story
there is a feature SNMP community indexing supported by many vendors. Using this feature we can send an SNMP request with an SNMP community combined with some instance index, in the form [email protected]
For example, if you want to receive some information related only to specific vlan, like mac addresses least, or spanning-tree protocol counters, you need to use community in the form [email protected] Here is an explanation on the Cisco official site, but the feature is supported by different vendors https://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-protocol-snmp/40367-camsnmp40367.html
The problem is that PRTG doesn't support different SNMP communities for sensors in the same device. And the proposal from Paessler to create separate hosts for each community looks too difficult because in this case, you need to create a separate host for each vlan
Two possible ways of how to implement this feature:
1) Allow using different SNMP credentials for sensors in the same device
2) Add a field "SNMP community string index" to sensors, to use it in SNMP queries.
