Openshift shipping lower version of hawkular
{"MetricsService": "STARTED","Implementation-Version":
"0.21.7.Final-redhat-1","Built-From-Git-SHA1":
"0ed89b2dbd78208177f39a7ac880f5cec3eda8f8"}
is there any way it can be bumped up latest to take advantage of tag language?

Patric
Thanks for pointing Grafant plug-in for Hawkuarl. We already invested effort
and time on TICK setup where metrics are collected via telegraf, InfluxDB and
Grafant. This plug-in is nice on top of our Grafana setup. However, telegraf
Docker plugin is much more advanced and have more metrics then Hawkular metrics.
Also, I noticed tags not working. Searching by name is pathetic and pretty
slow. Only gauge working . Other 2 metrics types like count, and availability
not working. Not sure why…
Even Hawkular also not showing any information regarding PVC or PV.

The system that would track this is Heapster but it doesn't appear to. There
are a few open issues:
https://github.com/kubernetes/heapster/issues/885
https://github.com/kubernetes/heapster/issues/1270
The other option would be Hawkular Openshift Agent:
https://github.com/hawkular/hawkular-openshift-agent
This means that the pod mounting your PVC needs to have some sort of agent that
reports filesystem usage. Sometimes this makes sense. For instance I am using
https://github.com/wrouesnel/postgres_exporter to export other PostgresSQL
stats and one of those is filesystem usage. In other cases it may not make as
much sense.
Both of these are a little odd since they would track pod volume usage, not
necessarily a specific PVC. It would be nice to somehow monitor usage of a PVC
directly but that is hard since the PVC is not always mounted on any node.
Lastly if you want to be able to display the stats generated by Heapster or
Hawkular Openshift Agent you can set up
https://github.com/hawkular/hawkular-grafana-datasource.

Does Openshift has any mechanism to track PV/PVC usage? PV/PVC are getting
filled but there is no mechanism for us or our clients to track what is current
utilization? One way to check is , platform teams or clients has to check
usage by mounting the PV somewhere and check by using OS commands like du etc.
wondering any better way to track each PVC usage and alert if they reach 90 %
threshold etc. Our monitoring systems can handle alerts but looking for a API
call or better simple way to check PVC usage
Don’t’ want to use OS commands to check or track usage.
