Description Lukas Svaty 2017-12-07 16:28:30 UTC

Description of problem:
Once the metrics are deployed on the engine, it is not being provisioned again. We should be able to notify the admin of ovirt that in case he added new hosts to the datacenter and forgot to rerun metrics playbook, that some of the hosts are unconfigured. Preferably by a webadmin event.

Also, it might be good to check regularly fluentd/collectd is running on all hosts and engine.

Comment 1 Shirly Radco 2017-12-12 08:04:50 UTC

New hosts should be configured during host deploy.

To check regularly fluentd/collectd is running on all hosts and engine user can set cron job that will run the manage_services role and start the services if needed.


Yaniv, is documentation on how to do that is enough?

Should be good enough.

Comment 3 Yaniv Kaul 2018-02-26 12:32:24 UTC

Please add a small playbook that goes over all oVirt hosts and checks if they are already configured or not (lets check configuration and that services are up).

Comment 4 Sandro Bonazzola 2019-01-28 09:44:17 UTC

This bug has not been marked as blocker for oVirt 4.3.0.
Since we are releasing it tomorrow, January 29th, this bug has been re-targeted to 4.3.1.

Comment 8 Shirly Radco 2020-06-21 11:55:46 UTC

Step for testing:

1. Run the playbook 'manage-ovirt-metrics-services.yml' by running:

/usr/share/ovirt-engine-metrics/configure_ovirt_machines_for_metrics.sh --playbook=manage-ovirt-metrics-services.yml

2. Check file /etc/ovirt-engine-metrics/hosts_not_configured_for_metrics

Comment 9 Guilherme Santos 2020-07-11 13:27:40 UTC

Verified on:
ovirt-engine-4.4.1-0.1.el8ev.noarch
ovirt-engine-metrics-1.4.1.1-1.el8ev.noarch

Steps:
1. have metrics running and configured
2. logged in one of the hosts and deleted all collectd/ryslog data (as well stopping collectd service)
# rm -rf /etc/collectd.d/* && rm -rf /etc/rsyslog.d/* && systemctl stop collectd 
1. # /usr/share/ovirt-engine-metrics/configure_ovirt_machines_for_metrics.sh --playbook=manage-ovirt-metrics-services.yml
3. once above step concluded: # cat /etc/ovirt-engine-metrics/hosts_not_configured_for_metrics

Results:
File present, containing info about host the doesn't have metrics properly configured
