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.
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

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,

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.

Hi Shirly,
I know about the grafana integration with the DWH.
I know about oVirt Metrics, I saw the video with you presenting this
product and read the docs. I also tried to install the Metrics store.
You could find some mail in in this mailing list about that. I was not
able to run it successfully. You were included in that communication.
I could try it again, but this is too big for or needs ;(
The basic idea is to integrate it into zabbix, which is our primary
monitoring system for whole datacenter, infrastructure, VmWare, .. I
do not want to add new screen for our NOC to watch on.
Generally I was interested in data flow how the data are collected
from HOSTS to ENGINE database.
The flow for metrics I guess is
libirt or vdsm(host) <- collectd (host) -> log files?? (host) <-
fluend (host) -> elk (metrics).
This is really nice example how to glue the components together. ;)
