Hi all!
Good news, we have enabled health checks for all the webservices running on
toolforge.
There's no action required on your part, the next time you restart or
stop/start your webservice, it will have a tcp health check by default (just
making sure something is listening).
The most interesting feature though is being able to pass a url to use as HTTP
health check.
To do so you can pass `--health-check-url /path/to/health` to your `toolforge
webservice start` command, and toolforge will automatically restart your
webservice if it stops responding to that path (you can change the path to
whatever you want, ex. `/`).
Note that this url will be queried quite often, so try to avoid hitting a page
that uses many resources.
Also a reminder that you can find this and smaller user-facing updates about
the Toolforge platform features here:
