Apache Module mod_lbmethod_heartbeat

Available Languages:  en  |  fr 

Description:Heartbeat Traffic Counting load balancer scheduler algorithm for mod_proxy_balancer
Status:Experimental
Module Identifier:lbmethod_heartbeat_module
Source File:mod_lbmethod_heartbeat.c
Compatibility:Available in version 2.3 and later

Summary

lbmethod=heartbeat uses the services of mod_heartmonitor to balance between origin servers that are providing heartbeat info via the mod_heartbeat module.

This modules load balancing algorithm favors servers with more ready (idle) capacity over time, but does not select the server with the most ready capacity every time. Servers that have 0 active clients are penalized, with the assumption that they are not fully initialized.

Support Apache!
