Monitoring

Monitoring the environment can be broadly categorized as:

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

Active Server and Service Availability Monitoring

Neverfail monitors the availability of a server by sending continuous heartbeat signals via the Neverfail 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 Neverfail Management Client.

Application and Performance Monitoring

Neverfail for File Server relies on the 'System' plug-in for monitoring general system performance. The Neverfail 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. Neverfail 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 Rules are available by default:

  • Logon/Sec
  • Files Open
  • Server Sessions
  • Mean Response Time

To create/modify user defined 'Rules' follow the steps below:

  1. Using the Management Client, click on Application: Rules .
  2. Select the desired 'Rule'.
  3. Click on the Edit button at the top of the Rules pane.
  4. Configure/modify the desired fields (listed below).
    • Condition: (the condition being evaluated)
    • Duration: (the length of time the condition exists)
    • First Failure: (action to take upon first failure) Note: The default is set to Alert .
    • Second Failure: (action to take upon second failure) Note: The default is set to Alert .
    • Third Failure: (action to take upon third failure) Note: The default is set to Alert .
  5. Click OK to save the changes.

Note: This dialog is also used to Enable/Disable the selected 'Rule'.

Tasks - There are no configurable 'Tasks' associated with this plug-in. Custom User defined 'Tasks' can be defined by following the steps below.

To configure a new 'Task', follow the steps below:

  1. Using the Management Client, click on Applications: Tasks .
  2. Click on the Add button at the top of the 'Tasks'  pane.
  3. Enter the appropriate information completing all fields in the dialog.
  4. Click OK to save the changes.

Note: This dialog is also used to Enable/Disable the selected 'Task'.

Disk Quotas

Neverfail for File Server Plug-in supports protection of Disk Quotas (see limitations in the Unsupported Components and Features below). To enable Disk Quota protection:

Note: After creating a shadow copy and then modifying the Disk Quota limits, if a rollback is performed, the previous Disk Quota limits will not be restored (Ref - 14289).

Important: When configuring protection of Disk Quotas, Orphaned File Deletion must be enabled.

  1. Using the Neverfail Heartbeat Management Client, navigate to Applications: Plug-ins .
  2. Select the Neverfail for File Server Plug-in .
  3. Click Edit .
  4. Select the ProtectQuotas to enable the option and click OK .
  5. Navigate to Application: Rules .
  6. Select both the ProtectDiskQuotas and ProtectQuotaSettings rules and select Edit .
  7. Select to enable both rules and click OK .
  8. Select the ProtectDiskQuotas and ProtectQuotaSettings rules and click Check Now.
  9. Run (or wait for) File Filter Discovery to complete. To run File Filter Discovery, navigate to Applications: Tasks . Select FileServer, right click File Filter Discovery and click Run Now.
