Summary

-
This document is still under development.
+

+mod_heartmonitor listens for server status messages generated +by mod_heartbeat enabled origin servers and makes their status +available to mod_lbmethod_heartbeat. This allows +ProxyPass to use the "heartbeat" +lbmethod inside of ProxyPass. +

+ +

This module uses the services of mod_slotmem_shm when +available instead of flat-file storage. No configuration is required to +use mod_slotmem_shm.

+ +
+ To use mod_heartmonitor, + mod_status and mod_watchdog + must be either a static modules or, if a dynamic module, it must + be loaded before mod_heartmonitor. +
