Monitoring Interprocess Communication in Cluster Configurations

The Cluster Interconnect window provides information about interprocess communication in a cluster configuration.

The Cluster Interconnect window provides detailed interprocess communication information for each instance of the cluster.

  1. In the Perspective Resources view, select a shared-disk cluster, click the drop-down arrow and click Monitor.
  2. To show the Cluster Interconnect screen, select Cluster Interconnect from the left pane.
    The Cluster Interconnect window displays information pertaining to each cluster instance, including instance name, count of received, transmitted, multicast and retransmitted messages, and count of successful and failed switches. Additional tabs show more information about CIPC (cluster interprocess communication) links, messages, channels, and endpoints.
  3. (Optional) Click a tab at the top of the screen to display more CIPC information on individual instances. By default, the CIPC tab is selected.
    • CIPC – displays the current status for each CIPC link. Status information for each instance includes the instance name, count of received, transmitted, multicast and retransmitted messages, and count of successful and failed switches.
    • CIPC Links – displays the current status for each CIPC link. Status information for each instance includes the ID, local and remote interfaces, passive and active states, and ages of passive and active states.
    • CIPC Mesh – displays cluster instance name, channel name, far-end cluster instance, received and transmitted message counts, and dropped, re-sent and retried messages. There is a Message Send Queue summary with send queue and sent queue information. The send queue includes current messages waiting to be sent to the instance, while the sent queue includes sent messages whose notification has not been processed.
    • CIPC EndPoints – displays cluster instance name, endpoint name, received and transmitted message counts, and received and transmitted byte counts. There is also a Message Received Summary with received queue and done queue information. The received queue includes messages queued for this logical endpoint. The done queue includes messages for this logical endpoint that have been processed, and await further action.
