/config/app/health/monitor//serverDown

The nodes below this one perform the functions described in this function overview.

Criteria to move a server from up to down.

Use

Use to determine when a server that is up should be marked as down, because the specified number of health probes has failed. The values in the threshold and window nodes become a ratio. The ratio should take into account network and other transient conditions that may cause health probes to fail, but which you want to disregard.

For example, if you enter 8 (threshold) and 10 (window), the 8/10 ratio sets the threshold for marking the server as down to the failure of 8 out the last 10 health probes. If the health probe fails 8 out of the last 10 times, the system takes the server offline.

When the system takes a server offline, the system no longer sends traffic to that server.
