To solve issues related to your installation, you can do several actions to get information about what is going wrong.

Error logs

Main error logs are stored in the /opt/zou/gunicorn_error.log file. Errors can be explicit. They can tell what is going wrong.

Status route

To know if all the required services are up, you can connect to the following route:

You should see something like this:

    "version": "0.11.3",
    "event-stream-up": true,
    "database-up": true,
    "key-value-store-up": true,
    "name": "Zou"

If one of the service is set to false, it means that it is down or that Zou cannot connect to it. Zou cannot run properly in that case.

NB: Database refers to Posgres, Key Value Store refers to Redis and Event Stream refers to zou-events.
