Healthcheck of Trilio

Trilio is composed of multiple services, which can be checked in case of any errors.

Verify the Trilio Appliance

Verify the services are up

Trilio is using 4 main services on the Trilio Appliance:

wlm-api
wlm-scheduler
wlm-workloads
wlm-cron

systemctl | grep wlm
  wlm-api.service          loaded active running   workloadmanager api service
  wlm-cron.service         loaded active running   Cluster Controlled wlm-cron
  wlm-scheduler.service    loaded active running   Cluster Controlled wlm-scheduler
  wlm-workloads.service    loaded active running   workloadmanager workloads service

Those can be verified to be up and running using the systemctl status command.

Check the Trilio pacemaker and nginx cluster

The second component to check the Trilio Appliance's health is the nginx and pacemaker cluster.

Verify API connectivity of the Trilio Appliance

Checking the availability of the Trilio API on the chosen endpoints is recommended.

The following example curl command lists the available workload-types and verifies that the connection is available and working:

curl http://10.10.2.34:8780/v1/8e16700ae3614da4ba80a4e57d60cdb9/workload_types/detail -X GET -H "X-Auth-Project-Id: admin" -H "User-Agent: python-workloadmgrclient" -H "Accept: application/json" -H "X-Auth-Token: gAAAAABe40NVFEtJeePpk1F9QGGh1LiGnHJVLlgZx9t0HRrK9rC5vqKZJRkpAcW1oPH6Q9K9peuHiQrBHEs1-g75Na4xOEESR0LmQJUZP6n37fLfDL_D-hlnjHJZ68iNisIP1fkm9FGSyoyt6IqjO9E7_YVRCTCqNLJ67ZkqHuJh1CXwShvjvjw

Please check the API guide for more commands and how to generate the X-Auth-Token.

On Red Hat OpenStack and TripleO

On controller node

Make sure the Trilio dmapi and horizon containers (shown below) are in a running state and no other Trilio container is deployed on controller nodes. If the containers are in restarting state or not listed by the following command then your deployment is not done correctly. Please note that the 'Horizon' container is replaced with the Trilio Horizon container. This container will have the latest OpenStack horizon + Trilio's horizon plugin.
