apache-mod_heartbeat znver1 7fad5bef18f74f10eb2119abe46b5b8fe419d269cff0e9aa61bdfb2d51df64b2 sends messages with server status to frontend proxy mod_heartbeat sends multicast messages to a mod_heartmonitor listener that advertises the servers current connection count. Usually, mod_heartmonitor will be running on a proxy server with mod_lbmethod_heartbeat loaded, which allows ProxyPass to use the "heartbeat" lbmethod inside of ProxyPass. mod_heartbeat itself is loaded on the origin server(s) that serve requests through the proxy server(s). To use mod_heartbeat, mod_status and mod_watchdog must be either a static modules or, if a dynamic module, must be loaded before mod_heartbeat. bero <bero@lindev.ch> https://httpd.apache.org
