After the installation and configuration of Trilio for Openstack did succeed the following steps can be done to verify that the Trilio installation is healthy.
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.
systemctl status wlm-api

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:
Run the following command on “nova-api” nodes and make sure “triliovault_datamover_api” container is in started state.
[root@controller ~]# docker ps | grep triliovault_datamover_api
3f979c15cedc trilio/centos-binary-trilio-datamover-api:4.2.50-victoria "dumb-init --single-…" 3 days ago Up 3 days triliovault_datamover_api
Datamover service (tvault-contego)
Run the following command on "nova-compute" nodes and make sure the container is in a started state.
[root@compute1 ~]# docker ps | grep triliovault_datamover
2f1ece820a59 trilio/centos-binary-trilio-datamover:4.2.50-victoria "dumb-init --single-…" 3 days ago Up 3 days triliovault_datamover
Trilio Horizon integration
Run the following command on horizon nodes and make sure the container is in a started state.
[root@controller ~]# docker ps | grep horizon
4a004c786d47 trilio/centos-binary-trilio-horizon-plugin:4.2.50-victoria "dumb-init --single-…" 3 days ago Up 3 days (unhealthy) horizon
On Canonical OpenStack
Run the following command on MAAS nodes and make sure all trilio units like trilio-data-mover, trilio-dm-api, trilio-horizon-plugin, trilio-wlmare in active state
root@jujumaas:~# juju status | grep trilio
trilio-data-mover 4.2.51 active 3 trilio-data-mover jujucharms 9 ubuntu

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.
