Web LinksUse this property page to view or edit the transmit frequency and tolerance settings for all nodes in the cluster, including the master node. The master node is generally the first node brought online in the cluster, but if that node fails, any of the other nodes in the cluster can become master.
Heartbeat (seconds)
The amount of time between transmits for all nodes in the cluster except the master. For example, if you set this value to 1, non-master nodes in the cluster will send a signal that they are alive to the master node every second.
Tolerance (seconds)
The amount of time the master node gives all other nodes in the cluster to signal that they are alive. For example, setting this value to 4 means that if the master node does not receive an "I'm alive" signal from a node in the cluster within four seconds, that node will be removed from the cluster.
Master Watchdog (seconds)
The amount of time between transmits for the master node in the cluster. For example, if you set this value to 1, the master node in the cluster will transmit an "I'm alive" signal to all the other nodes in the cluster every second.
Slave Watchdog (seconds)
The amount of time the master node has to signal that it is alive. For example, setting this value to 5 means that if the non-master nodes in the cluster do not receive an "I'm alive" signal from the master node within five seconds, the master node will be removed from the cluster and one of the other nodes will become the master node.
