Re: How to use curl to check if service is down?

[Anthony Ettinger]

One thing I'm not sure about is how monit knows which systemd service to restart. I haven't specified it anywhere.

Hello Anthony,
as long as you are sure the http status is 200, you can use this.

Unfortunately, in general you will get some other status codes too, but
this depends to your application.
I use an addition "... with timeout 30 seconds retry 5 then" to prevent
restart problems. And for "ssl" connections you can use "... and
certificate valid > 30 days ..." too.

if failed
   port 443 protocol http and request "/api/1" method GET
   status != 200
   with timeout 30 seconds retry 5
   then restart

See https://mmonit.com/monit/documentation/monit.html#HTTP
