Chapter 3. Deploying collectd and fluentd

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.

4. Optionally, if you need to connect an additional Red Hat Virtualization Manager or an additional elasticsearch installation, run the following commands to copy the engine public key to your Metrics Store virtual machine:

   # 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

5. Deploy collectd and fluentd on the hosts:

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