[ovirt-users] Re: data flow for statistics for hosts and vms
Hi Peter,
The dwh views do not change, we support legacy views fro 3.6, so we
recommend using DWH to get the statistics you want.
It is possible to connect grafana directly with DWH if that interest you.
Also, We have a new feature called "oVirt metrics store" that collectd many
statistics using and logs using fluentd to a central Elasticsearch and
Kibana.
I can elaborate on that if you want.
Best,

Hi,
I'm trying to understand the flow how the stats from the VM and HOSTS
are imported into the engine.
On each host there is VDSM. Using the vsdm-client I'm able to get HOST
and VM stats
vdsm-client Host getAllVmStats
vdsm-client Host getStats
Are the hosts pushing the data to the engine or vice versa? On the
engine side there is java based vdsm-jsonrpc client so I guess the
data are pulled from the hosts to the engine database.
Yes. Engine pulls the stats from the hosts every 15 seconds.
And of course the question is which component on engine side is
getting/requesting the data.
I'm trying to get the stat less painless as query the API.
Maybe the engine/dwh database could help but the scheme could change
between releases, isn't it. or the engine DB.
regards
Peter
