<summary>
|
|
<p><code>lbmethod=heartbeat</code> uses the services of <module
|
|
>mod_heartmonitor</module> to balance between origin servers that are providing
|
|
heartbeat info via the <module>mod_heartbeat</module> module.</p>
|
|
|
|
<p> 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.</p>
