NetApp Harvest and Grafana dashboards

Hello. I have some questions regarding Harvest and Grafana. Right now I 'm running version 1.4 and want to upgrade to version 1.4.2. I saw in the release notes that new dashboards for Grafana have been implemented.

 

Will re-importing the dashboards cause duplicates? Documentation says that existing dashboards of the same name will be overwritten. What happens with the data collected so far for those dashboards?

 

Thanks,

G

Re: NetApp Harvest and Grafana dashboards

Hello G,

 

The upgrade of Harvest is pretty safe for existing data.

 

First of all, regarding the actual performance data, this all happens in Graphite,a nd Harvest isn't touching, except to add new metrics, so a Harvest upgrade will never remove performance and capacity data.

 

Regarding your dashboards, you might have noticed that Harvest dahboards have special tags on it :

Only dashboards having these tags will be deleted and replaced (again, without touching the actual data), so if you have any dashboards of your own without these tags, they are safe as well.

 

Hope this helps.

Thanks Yann. I 'll give it a go and report back. My Harvest host is a VM anyway so I can snapshot it before the update.

Re: NetApp Harvest and Grafana dashboards

Oh, one other question that is not strictly related to Harvest, but it's more about Grafana. Any idea why for certain dashboards when I select anything different to All, I see no data? For example see below screenshot:

2019-05-01 17_42_22-Grafana - NetApp Dashboard_ Cluster.png

But when all clusters are selected then no problems at all:

Thanks,

Re: NetApp Harvest and Grafana dashboards

I think I figured it out. At least two resources need to be selected. Meh...

Re: NetApp Harvest and Grafana dashboards

That shouldn’t be the case, you should be able to select a single cluster in this dashboard

Re: NetApp Harvest and Grafana dashboards

Try a single cluster, but use one of those that are visible in the stat tables when using "All".

That specific one you just tried (not showing any data) might not have any statistics collected.

 

Re: NetApp Harvest and Grafana dashboards

Hi bkamil. That's not the case. And as I said I have noticed that behaviour with some of the other dashboards, eg the one for volumes. May be that's a Grafana bug. I have to update the host anyway to get new versions of all the software components. I 'll see how that goes and report back. Thanks

Re: NetApp Harvest and Grafana dashboards

The upgrade went well including (re-)importing (and adding) the (new) dashboards, however I still have the issue described in one of my previous posts when selecting a single resource in a Grafana dashboard. I 'll take that with the Grafana community, unless if somebody else has seen that behaviour before and found a solution. Thanks for the help all Smiley Happy

Re: NetApp Harvest and Grafana dashboards

I'm afraid the Grafana community won't be able to help, it has to be related to the data.

 

Can you share another screenshot of a cluster that displays data in "All", but nothing when selected ?
