| <h3>Summary</h3> |
| |
| <p>lbmethod=heartbeat uses the services of <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> to balance between origin servers that are providing |
| heartbeat info via the <code class="module"><a href="../mod/mod_heartbeat module.html">mod_heartbeat module</a></code>.</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> |
