I upgraded from 2.4.2 and i have tried fresh install of 2.5.1b and im unable to poll netapp capacity metrics for svm. Has anyone run into this issue.
You probably didn't configure OCUM poller. For capacity information, you need to have OCUM installed and configure it in NAbox.
If you just configure your cluster you will only get performance metrics.
OCUM is configured and running. In the logs i see this the errors below.
[2019-03-14 18:46:03] [WARNING] [volume] update failed with reason: Timeout. Could not read API response.
[2019-03-14 18:46:03] [WARNING] [volume] data-list update failed.
Are you sure that NAbox can communicate with OCUM over port 443 ?
If the answer is yes, any time I had a similar issue it was solved by an OCUM reboot...
Once in a while i would have to restart the OCUM services. I thought it was an upgrade issue when we upgrade NAbox from 2.4 to 2.5x but that was not the case. I also setup an entirely new instance on 2.5.1b and it still has the same issues. It is communicating over 443 to our OUCM instance it as performance data is being pulled in.
It seems like Harvest is getting late responses from your OCUM system. What you can do is change the default timeout parameter in Harvest and seek help from support for the OCUM API response time.
You can manually edit netapp-worker to change the default timeout setting. This file is usually located in the folder /opt/netapp-harvest/. You can use vim or nano to edit the file.
On line 612 you should see this:
$out = $s->set_timeout('60');
Change 60 to 180, save and restart Harvest. If it doesn't help, try again by setting it to 300.
I have exactly the same error. Can someone provide info for the fix. Communication between NAbox and OCUM via port 443 is working. Increasing timeout to 180 seconds didn't help.
