Yes, that's true, and if you are doing HA you have to be using a networking
backed storage. That's a good point !
It never happened to us

I imagine, yes. We don't use this at all, we don't mix HA and non HA VMs on the

It would be nice to have a unified view with all nodes ressources.
I was thinknig of doing this with an external metric server (graphite/grafana.)
Imho it is not relevant to aggregate ressources of the whole cluster, because
there is no mechanism of load balancing.
So you could have for ex : some

No, I mean for the cluster. Would be great to have those values
(cpu, ram, maybe IO ..) for the whole cluster monitored, I think.
Monitoring each node individually is nice, but that doesn't tell
you that you are almost out of ram on the cluster for

Why average on not total? If this is supposed to be a cluster wide
dashboard average gives no mening.

i agree, but with cpu usage it is not so easy
for exam

Looks good, it would be great to be able to get each values separatly

Hi all,
i am currently working on a cluster dashboard,
and wanted to get feedback from you all.
please be aware that this is a mockup only, no functionality yet,
so no patches for now
i will also post it on the forum (maybe tomorrow) to get
additional feedback
please discuss :)
ps: for clarif
