-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi SHIRLY, first why zabbix. Zabbix is our primary monitoring tool. Zabbix have native implementation for VmWare monitoring, which we of course use. The idea was to use the same monitoring system, alerting for our NOC. The performance problem is due the how zabbix works, especially zabbix agent. You could return only one value each query, to to get stat for VM you have to do about 10-15 queries. Zabbix agent needs to for the process ... So overhead is twice, to get the data using api and forking process. I see the grafana integration, https://www.ovirt.org/blog/2018/01/ovirt-report-using-grafana/. This seems to be dependent on oVirt version, as I see the table names. So my next steps are: a) I took look at the ovirt metrics, looks good. Is it stable on 4.2? b) take a look on zabbix sender, but this have another sets of issues. For example how to send data olny for some VM/Hosts, not for all if I do not want to monitor while platform. Data could be collected from API or DWH c) try to do the oVirt poller into zabbix ?? Generally what we need is monitoring and alerting system. - alert if Vm is down - alert if VM CPU usage is high for period of time - alert if there is storage problem /latency, usage, .../ Peter On 29/03/2018 08:41, Shirly Radco wrote:
Hi Peter,
Using the oVirt API will add load on the engine and may affect the engine performance. We have the DWH that collectd metrics and configuration data about the hosts and vms and can be used along with Grafana.
We also added the oVirt metrics store that collects the metrics directly from the host about the hosts and vms and from the engine about the machine itself and postgres db. This was done in order to lower the load on the engine. We also collect the engine.log and vdsm.log.
The metrics are collected to Elasticsearch and can be visualised in Kibana and Grafana and are collected in 10 sec interval that give you almost real time view. I would love to hear why you prefer using Zabbix for collecting the metrics data.
Best regards,

I have working proof-of-concept. There still could be bug in templates and not all parameters are monitored, but HOST and VM discovery is working.
I will try to share it on github. At this moment I have some performance issues, since it's using the zabbix-agent which needs to for a new process for each query ;(

Yes, template and python
at this moment I understand oVirt API. I needed to write own small SDK, since the oVirt SDK is using SSO for login, that means it do some additional requests for login process. There is no option to use Basic Auth. The SESSION reuse could be useful, but I do no want to add more
First I need to understand some basics from Zabbix Discovery Rules / Host Prototypes. I would like to have VM as separate hosts in Zabbix, like VMWare does. The other stuff is quite easy.
There plugin for nagios/icinga if someone using this monitoring tool https://github.com/ovido/check_rhev3 <https://github.com/ovido/check_rhev3>

Hi Peter,
This is interesting. Is it going to be a template with an external python script?

Hi Terry,
I started to work on ZABBIX integration based on oVirt API. Basically it should be like VmWare integration in ZABBIX with full hosts/vms discovery and statistic gathering.
The API provides for each statistics service for NIC, VM as wall CPU and MEM utilization.
There is also solution based on reading data from VDSM to prometheus

Dear all,
Now, we can just read how many storage used, cpu usage on ovirt dashboard. But is there any monitoring tool for monitoring virtual machine time to time? If yes, could you guys give me the procedure?
