Missing data from harvest after Data ONTAP upgrade

[fede_melaccio]

Hi,

after upgrading Data ONTAP from version 8.2.3 to 8.3.2, the Protocol Backend IOPs and the Disk MB/s charts in Grafana stopped showing the nfs_ops and the disk_data* metrics previously available. Looking at the harvest logs, the following messages started appearing right after the upgrade:

[2016-04-29 00:12:06] [WARNING] [wafl_hya_sizer] update of instance_list cache failed with reason: Object "wafl_hya_sizer" was not found.
[2016-04-29 00:12:06] [WARNING] [wafl_hya_sizer] instance-list update failed.
[2016-04-29 00:12:07] [WARNING] [disk] update of instance_list cache failed with reason: Object "disk" was not found.
[2016-04-29 00:12:07] [WARNING] [disk] instance-list update failed.
[2016-04-29 00:14:12] [WARNING] [system] update of data cache failed with reason: Object "system" was not found.
[2016-04-29 00:14:12] [WARNING] [system] data-list update failed.

and they are still logged. It looks like some relevant harvest objects changed name. How can we fix this? Thanks.

Best

Hi @fede_melaccio

When Harvest starts it determines the best collection template to use.  So if you update Data ONTAP between major releases [when there are likely template changes] you should restart Harvest so it will start using the new best template.

Hi Chris,

thanks for your prompt reply. By "harvest" do you mean the pollers?

Hi @fede_melaccio

Yes, Harvest is the project name for the poller software.

You can restart all pollers using:

/opt/netapp-harvest/netapp-manager -restart

Or, just the one cluster that you upgraded if you know the poller name like this:

[root@sdt-poller netapp-harvest]# ./netapp-manager -status
STATUS          POLLER               SITE
############### #################### ##################
[RUNNING]       blob1                nl
[RUNNING]       blob2                nl

[root@sdt-poller netapp-harvest]# ./netapp-manager -restart -poller blob1
STATUS          POLLER               SITE
############### #################### ##################
[STOPPED]       blob1                nl
[STARTED]       blob1                nl
