The conn_logd_intval directive specifies the time (in seconds) heartbeat will reconnect to the logging daemon if the connection between heartbeat and the logging daemon is broken.
conn_logd_intval <time in seconds>
Default is 60 (seconds)
Note: heartbeat will not automatically reconnect to the logging daemon. It only tries to reconnect when it needs to log a message and conn_logd_intval seconds have passed since the last attempt to connect.
