Answer by Tensibai for Health monitoring of web pages without using GET check

I see two way to solve this problem:

1. Check your logs often and ensure there was an access with code 200 in the last N seconds/minutes and no code 5xx meaning there's a server side error. (the often should be coherent with how long you are ok with no entries)

2. Keep an active check but:

   • use a HEAD request (so there's less data to return by the server)
   • use a custom user agent for the check
   • configure your log exporter to ignore this user agent.
   • take a larger check interval, 1 second is probably over obsessive

Depending on how often your sites are called you may wish to mix both methods to have a proper check even if there's no traffic from real clients.
