SNMP statistics collection after node becomes reachable again

NetWatch

Hello,

We have a use-case where we would like to send Node "last boot time" in recovery notifications (when the Node starts responding again after being unreachable for a while).

The "last boot time" comes from SNMP uptime, and is therefore subject to statistics collection interval. I was wondering if we can rely on the value stored by NPM at the time notification is generated? My fear is that this value might be outdated, if it was collected before the node became unreachable and not updated before the recovery notification was triggered... unless NPM triggers an immediate statistics collection when a Node becomes reachable again?

Thanks in advance, I'm trying to understand if our use-case makes sense or if we should look for other options.

Cheers!

My fear is that this value might be outdated, if it was collected before the node became unreachable and not updated before the recovery notification was triggered - Possible, there is a chance that this could happen. As well its not always necessary that SNMP was restarted on the end device, in some cases even if SNMP service is hung during polling - Node not responding happens and there are cases where your poller/polling engine itself has a problem and you would see Node not responding - hence this data 'last boot time' might not be 100% accurate for all possible scenarios.
