Monitoring

Monitoring the system environment can be broadly categorized as:

  • Active Server and Service Availability Monitoring
  • Application and Performance Monitoring

Active Server and Service Availability Monitoring

Continuous Availability 2011 monitors the availability of a server by sending continuous heartbeat signals via the Symantec Channel to the other server in the pair. The “Yes I am alive” response ensures that not only is the other server powered-up, but also that it is available if needed. The heartbeat signal interval is configurable from the Continuous Availability 2011 Management Client.

Application and Performance Monitoring

Continuous Availability 2011 monitors general system performance via the Symantec System Plug-in. The Symantec System Plug-in performs this operation by checking select WMI counters at predetermined intervals to ensure that results of the check are within defined parameters. Symantec System Plug-in uses 'Rules' to take action should a check reveal results outside of the defined parameters.

NOTE: Many of the rules listed below are provided in the disabled state because default values cannot be provided as these values depend upon the server and application load.

  • DiskAvgSecsPerRead
  • DiskAvgSecsPerWrite
  • DiskIO
  • DiskQueueLength
