All SNMP items go bad

[src386]

Hello everyone,

I'm writing a template to monitor Mikrotik devices (Networking) with SNMP.
This is a unique template for 2 models (RB and CCR).

Everything works just fine, I'm getting many items values.

But sometimes, every single item on the RB goes to red with the following errors :
- Invalid SNMP response : error index out of bounds.
- SNMP error: (noSuchName) There is no such variable name in this MIB.

This seems to be related with enabling unsupported items (RB does not have PSU monitoring for example, but CCR does).

Is it a bug ? 1 single unknown MIB objects breaks everything ?

Is there a workarround ? I want to use 1 template for all, but maybe there is a way to automatically enable/disable items. I though of autodiscover but the problem might be the same ?

Thanks.

Any update?

Having the same issue, cannot seem to get it resolved.

If the failing condition last long enough for you to catch it, try snmpget commands to see if you get the same results.

It seems that many SNMP devices are not trustworthy, they will quit responding for various reasons, too busy doing other things, or won't work until rebooted.

At other times, increasing the timeout value may be necessary if SNMP devices are slow or on slow networks.

Some devices update the size of tables, so LLD'ed item indexes will disappear if the table shrinks. You can set your LLD keep lost resources down if that is the case.
