Chapter 3. Deploying collectd and rsyslog

Procedure

1. Log in to the Manager machine using SSH.

2. Copy /etc/ovirt-engine-metrics/config.yml.example to create /etc/ovirt-engine-metrics/config.yml.d/config.yml:

   # cp /etc/ovirt-engine-metrics/config.yml.example /etc/ovirt-engine-metrics/config.yml.d/config.yml

3. Edit the ovirt_env_name and elasticsearch_host parameters in config.yml and save the file. These parameters are mandatory and are documented in the file.

   Note

   If you add a Manager or an Elasticsearch installation, copy the Manager’s public key to your Metrics Store virtual machine using the following commands:

   # mytemp=$(mktemp -d)
   # cp /etc/pki/ovirt-engine/keys/engine_id_rsa $mytemp
   # ssh-keygen -y -f $mytemp/engine_id_rsa > $mytemp/engine_id_rsa.pub
   # ssh-copy-id -i $mytemp/engine_id_rsa.pub root@{elasticsearch_host}
   # rm -rf $mytemp

4. Deploy collectd and rsyslog on the hosts:

   # /usr/share/ovirt-engine-metrics/setup/ansible/configure_ovirt_machines_for_metrics.sh
