Using Graphite (or Grafana) to show statistics over whole install base (aggregated)

[marcinlubojanski]

Hello,
I'm trying to get some statistics that are global for my whole install base, f.e. average/median amount of iops per LUN/volume. 

We are using nabox appliance for Graphite, Grafana & Harvest. 

I haven't used Graphite before.I was trying to edit Graphite dashboard like this:

[
  {
  "target": [
    &target=aggregate(netapp.perf.OW*.svm.*.vol.*.total_ops, "median")
  ]
  }
]

 It doesn't display any error but also doesn't work. I believe I'm doing some simple mistake here. Can someone point me into the right direction ?

Hi,

there is a very good online documentation about all the available graphite functions: https://graphite.readthedocs.io/en/1.0.2/functions.html

In the Standard Edit Mode of Grafana you don't have to deal with the syntax and you get suggestions for the available functions.

I think "averageSeries" will do what you want.
