23.2. Sending metrics to a remote instance of Elasticsearch

Note

Red Hat does not own or maintain Elasticsearch. You need to have a working familiarity with Elasticsearch setup and maintenance to deploy this option.

You can configure the Red Hat Virtualization Manager and hosts to send metrics data to your existing Elasticsearch instance.

To do this, run the Ansible role that configures collectd and rsyslog on the Manager and all hosts to collect engine.log, vdsm.log and collectd metrics, and send them to your Elasticsearch instance.

23.2.1. Installing collectd and rsyslog

Deploy collectd and rsyslog on the hosts to collect logs and metrics.

Note

You do not need to repeat this procedure for new hosts. Every new host that is added is automatically configured by the Manager to send the data to Elasticsearch during host-deploy.

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. Add the following variables: 

    use_omelasticsearch_cert: false
viaq_metrics_store: false
rsyslog_elasticsearch_usehttps_metrics: !!str off
rsyslog_elasticsearch_usehttps_logs: !!str off

  4. Deploy collectd and rsyslog on the hosts: 

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