+mod_heartbeat
+
+Broadcasts the current Apache Connection status over multicast.
+
+Example Configuration:
+ HeartbeatAddress 239.0.0.1:27999
+
+Dependencies:
+ mod_status must be either a static module, or if a dynamic module, it must be
+ loaded before mod_heartbeat.
+
+
+Consuming:
+ Every 1 second, this module generates a single multicast UDP packet,
+ containing the number of busy and idle workers.
+
+ The packet is a simple ASCII format, similar to GET query parameters in UDP.
+
+ An Example packet:
+ v=1&ready=75&busy=0
+
+ Consumers should handle new variables besides busy and ready, separated by '&'
+ being added in the future.
+
+Misc:
+ The interval of 1 seconds is controlled by the HEARTBEAT_INTERVAL
+ compile time define. This is not currently tunable at run time. To make this
+ module send the status packet more often, you must add to the CFLAGS used to
+ compile the module to include:
+ -DHEARTBEAT_INTERVAL=3
+ Would cause the broadcasts to be sent every 3 seconds.

+Collects the Apache Connection status data over multicast.

+Example Configuration:
+ # First parameter is the interface to listen on
+ HeartbeatListen 239.0.0.1:27999
+ # Absolute path, or relative path to ServerRoot
+ HeartbeatStorage logs/hb.dat
+
+Dependencies:
+ Due to a bug in APR's apr_socket_recvfrom, version 1.2.12 or newer must be
+ used:
+ <http://svn.apache.org/viewvc?view=rev&revision=467600>
+
+Consuming:
+ This module atomically writes to the configured path, a list of servers,
+ along with metadata about them.
+
+ Included data about each server:
+ - IP Address
+ - Busy Slots
+ - Open Slots
+ - Last Seen
+
+ Every 5 seconds, this file will be updated with the current status of the
+ cluster.
