Heart Beats Configuration

Item

Description

Keep alive time

The keep alive directive sets the interval between heartbeat

packets. It is specified according to the Heartbeat time syntax.

Dead time

The dead ping directive is used to specify how quickly Heartbeat

should decide that a ping node in a cluster is dead. Setting this

value too low will cause the system to falsely declare the ping

node dead. Setting it too high will delay detection of

communication failure.

This feature has been replaced by the more flexible ping

resource agent in Pacemaker, and should no longer be used.

Warning time

The warn time directive is used to specify how quickly Heartbeat

should issue a "late heartbeat" warning.

Initial dead time

The initial dead parameter is used to set the time that it takes to

declare a cluster node dead when Heartbeat is first started. This

parameter generally needs to be set to a higher value, because

experience suggests that it sometimes takes operating systems

many seconds for their communication systems before they

operate correctly.

UDP port

The udp port directive specifies which port Heartbeat will use

for its UDP intra-cluster communication. The default value for

this parameter is UDP 694 port.
