Healthcheck of TrilioVault

TrilioVault is composed of multiple services, which can be checked in case of any errors.
Verify the TrilioVault Appliance
Verify the services are up
TrilioVault is using 4 main services on the TrilioVault 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.

Verify API connectivity of the TrilioVault Appliance
Checking the availability of the TrilioVault 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 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 + TrilioVault's horizon plugin.
