Verify the OpenContrail status¶

To ensure that OpenContrail is up and running, verify the status of all the OpenContrail-related services. If any service fails, restart it as described in Restart the OpenContrail services.

For OpenContrail 4.x

1. Log in to the Salt Master node.

2. Apply one of the following states depending on the Build ID of your MCP cluster:

   • For MCP Build ID 2018.11.0 or later:

     salt -C 'ntw* or nal*' state.sls opencontrail.upgrade.verify
     

     If the state is applied successfully, it means that all OpenContrail services are up and running.

   • For MCP Build ID 2018.8.0 or 2018.8.0-milestone1:

     salt -C 'ntw* or nal*' cmd.run 'doctrail all contrail-status'
     

     In the output, all services must be either in active or backup (for example, for contrail-schema, contrail-svc-monitor, contrail-device-manager services) state.

For OpenContrail 3.2

Eventually, all services should be active except for contrail-device-manager, contrail-schema, and contrail-svc-monitor. These services are in the active state at only one OpenContrail controller ntw node in the cluster switching dynamically between the nodes in case of a failure. On two other OpenContrail controller nodes, these services are in the backup state.

To verify the OpenContrail services status, apply the following state for the OpenContrail ntw and nal nodes from the Salt Master node:

salt -C 'ntw* or nal*' cmd.run 'contrail-status'
