Getting the Average Time Taken To Start CMM Services

To get the average time in seconds between nodes when starting the CMM, invoke the getAverageElectionDelay method. The getAverageElectionDelay method takes no parameters, and returns an int. This information can be used for tuning the election mechanism. This information is available on the master node only.

Getting the Number of Master Elections Performed on a Node

To get the number of elections processed on the platform, invoke the getElectionCount method. The getElectionCount method takes no parameters, and returns an int. This information is available on the master node only.

Getting the Maximum Time Taken to Elect a Master Node

To get the maximum time in seconds between nodes when starting the CMM, invoke the getMaxElectionDelay method. The getMaxElectionDelay method takes no parameters, and returns an int. This information can be used for tuning the election mechanism. This information is available on the master node only.

Getting the Minimum Time Taken to Elect a Master Node

To get the minimum time in seconds between nodes when starting the CMM, invoke the getMinElectionDelay method. The getMinElectionDelay method takes no parameters, and returns an int. This information can be used for tuning the election mechanism. This information is available on the master node only.

Getting the Number of Nodes Present

To get the number of nodes acknowledged by the master node as being present in the cluster, invoke the getPresentNodeCount method. The getPresentNodeCount method takes no parameters, and returns an int. This information is available on the master node only.

Getting the Number of Switchovers Performed

To get the number of switchovers performed, invoke the getSwitchOverCount method. The getSwitchOverCount method takes no parameters, and returns an int. This information is available on the master node only.

Getting the Number of Currently Connected CMM Clients

To get the number of CMM clients currently connected, invoke the getClientCount method. The getClientCount method takes no parameters, and returns an int. This information is available on all nodes.

Getting the Number of Outstanding Requests

To get the number of requests currently outstanding, invoke the getRequestCount method. The getRequestCount method takes no parameters, and returns an int. This information is available on all nodes.

Getting the Lifetime of the CMM on a Node

To get the lifetime of the CMM on this node, expressed in the number of seconds since boot, invoke the getCmmUpTime method. The getCmmUpTime method takes no parameters, and returns an int. This information is available on all nodes.
