We have a collection of routers (about 350) which are made up of a variety of different models. Some of these devices provide support for retrieving the hardware serial number and a variety of other SNMP OIDs (eg Temperature).
I initially simply added all the SNMP OIDs I wanted to monitor to a template, which was applied to all the routers. Those that weren't supported would simply not be recorded but this causes a problem with bulk SNMP requests as a single error invalidates the entire request. Turning off bulk requests has a major impact on the system's scalability and everything essentially immediately grinds to a halt.
I assume I could create a SNMP LLD (low level discovery) rule to add the required items by way of item prototype, but this doesn't allow me update the host inventory fields as the 'Populates host inventory field' option isn't present. I understand why it wouldn't be (you can only link a single item to update host inventory).
How are other people handling this?
I would really like the process not to rely on staff having to remember to apply templates manually and would really appreciate it being automated.
