Solved: NetApp Harvest error: [nic_common] plugin failed to compile - Page 2

Collection on one of my 8.3.2.P2 clusters stopped with the errors below logged. All other clusters seem to be fine. Has anyone seen this?

Hi @dlmaldonado

There appears to be an issue with the link_speed counter value on some interface(s) on your cluster. My guess is either something changed in 8.3.2P2, or after the upgrade/reboot some unused interface didn't get a value set as it should (which could also be a new behavior in 8.3.2P2).

Can you restart the poller in verbose mode, wait for 5 minutes, and then restart again in normal mode?:

/opt/netapp-harvest/netapp-manager -restart -poller <clustername> -v

<wait 5 minutes>

/opt/netapp-harvest/netapp-manager -restart -poller <clustername>

Then provide the logfile in /opt/netapp-harvest/log/<poller>_netapp-harvest.log

From that log I can see what the incoming link_speed values are and hopefully explain why it's not working as it should.

I will also send you a private message in case you prefer to share the logs privately.
