API availability - Database connection

[hughpearse]

We need a way to check if the model databases are online.

According to the following page:

https://docs.looker.com/setup-and-management/on-prem-install/monitoring-instance

There are two simple ways to validate that your Looker instance is running.

1. Append /alive to your Looker instance’s URL like this:

   https://instance_name.looker.com/alive

   If your instance is able to respond to a web request you’ll receive a 200 OK HTTP status code.

2. Append /availability to your Looker instance’s URL like this:

   https://instance_name.looker.com/availability

   This URL performs a more complete check of several underlying subsystems and will also respond with a 200 OK HTTP status code if all is well.

What does “/availability ” do? Which underlying subsystems does it check?

Does Looker reflect a model database outage in its “/availability ” endpoint?

If models are unable to load due to a DB connection issue, but the looker application is online, is there a way to check the health of all the models?
