EVault - EVault System Plug-in - Feature List



The EVault System Plug-in is an add-on to EVault Remote Disaster Recovery, which monitors system performance. It monitors the critical hardware and operating system performance that could affect system availability.

More Information

Supported Versions of Microsoft Windows

x86 Platform (32-bit hardware)

  • Microsoft Windows 2000 SP4 & SR
  • Microsoft Windows 2003 SP1/SP2

x64 / Intel 64 Platform (64-bit hardware)

  • Microsoft Windows 2003 SP1/SP2

Note: The IA-64 Itanium Platform is not supported.


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

EVault Remote Disaster Recovery monitors the availability of a server by sending continuous heartbeat signals via the EVault 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 EVault Remote Disaster Recovery Management Client.

Application and Performance Monitoring

EVault Remote Disaster Recovery monitors general system performance via the EVault System Plug-in. The EVault 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. EVault 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.

Rules - The following Performance Monitoring 'Rules' are installed by the EVault System Plug-in:

  • DiskAvgSecsPerRead
  • DiskAvgSecsPerWrite
  • DiskIO
  • DiskQueueLength
  • DiskReadsPerSec
  • DiskWritesPerSec
  • DiskWriteable
  • FreeDiskSpace
  • FreeDiskSpaceOnDrive
  • MemoryCommittedBytes
  • MemoryCommittedBytesPercent

  • MemoryPagesPerSec
  • MemoryPagingFileUseage
  • PageFaultsPerSec
  • ProcessorIntsPerSec
  • ProcessorLoad
  • ProcessorQueueLength
  • RedirectorBytesTotalPerSec
  • RedirectorNetworkErrorsPerSec
  • ServerBytesTotalPerSec
  • ServerWorkItemShortages >= 3 (if the rule for server work item shortages is triggered, consult Microsoft documentation on setting the registry values for InitWorkItems or MaxWorkItems accordingly).
  • ServerWorkQueueLength
  • SystemContextSwitches

Tasks - There are no configurable 'Tasks' associated with this plug-in.
