The monitor issues a status check every 1200 seconds. If a status check does not get an OK response within 16 seconds, it will be marked down.

 

If the first check attempt fails to get a response before the timeout period (16 seconds), the member is marked down.

 

The next check will be 1184 (1200-16) seconds after the pool is marked down. If the pool member responds within 16 seconds, then the member will be marked up and will stay marked up until the next check 1200 seconds later.
