Counter definitions
Name Key Description Version Granularity Type Level Number of message buffer reallocations DCSStats.numOfReallocs Number of message buffer reallocations due to inadequate buffer size. If this number is larger than 20 percent of the number of sent messages, you may want to contact IBM Support 6.0 and above Per DCS stack CountStatistic Medium Outgoing message size DCSStats.outgoingMessageSize Minimal, maximal, and average size (in bytes) of the messages that were sent through the DCS stack 6.0 and above Per DCS stack AverageStatistic High Number of sent messages DCSStats.outgoingMessageCounter Number of messages sent through the DCS stack 6.0 and above Per DCS stack CountStatistic High Incoming message size DCSStats.incomingMessageSize Minimal, maximal and average size (in bytes) of the messages that were received by the DCS stack 6.0 and above Per DCS stack AverageStatistic High Number of received messages DCSStats.incomingMessageCounter Number of messages received by the DCS stack 6.0 and above Per DCS stack CountStatistic High Amount of time needed for the synchronization procedure to complete DCSStats.vsCompleteCurrentTime Amount of time needed to guarantee that all view members are synchronized. 6.0 and above Per DCS stack TimeStatistic High Number of messages retransmitted by local member during the view change DCSStats.numOfVSCompletionMessages Number of messages that were retransmitted during the view change to ensure synchronization with other members. 6.0 and above Per DCS stack AverageStatistic High Number of times that the synchronization procedure timed out DCSStats.vsTimetoutExpiredCounter Number of times that the synchronization procedure timed out. 6.0 and above Per DCS stack CountStatistic Medium Number of times that a high severity congestion event for outgoing messages was raised DCSStats.transmitterCongestedCounter Number of times that a high severity congestion event for outgoing messages was raised. 6.0 and above Per DCS stack CountStatistic Medium Coalesce Time DCSStats.coalesceTime Measures the amount of time it actually takes to coalesce a view. 6.0 and above Per DCS stack TimeStatistic Medium Join View Change Time DCSStats.mergeTime Measures the time to do a merge view change. The DCS stack is blocked during this time. 6.0 and above Per DCS stack TimeStatistic High Remove View Change Time DCSStats.splitTime Measures the time to do a split view change.The DCS stack is blocked during this time. 6.0 and above Per DCS stack TimeStatistic High Number of suspicions DCSStats.suspectCounter Measures the number of times that the local member suspected other members. 6.0 and above Per DCS stack CountStatistic High Number of view changes DCSStats.viewCounter Number of times that this member underwent view changes. 6.0 and above Per DCS stack CountStatistic Medium View group size DCSStats.groupSize Measures the size of the group the local member belongs to. 6.0 and above Per DCS stack AverageStatistic Medium
