Monitoring the CTERA Edge Filer and CTERA Edge Filer Logs

The CTERA Edge Filer dashboard provides an overview of the CTERA Edge Filer's current status, including the following:

• Disk drive and volume information
• Resource utilization information
• Recent logged events
  In addition, it provides shortcuts to configuring arrays, drives, and volumes.

To view the Status Dashboard:

• In the Configuration view, select Main > Dashboard in the navigation pane.
  

The dashboard displays the following information:
Hard Disk Drives – All disk drives installed on the CTERA Edge Filer. For each drive:

• The disk type. Click this link to view additional information about the drive.
• The disk size.
• The array to which the disk is assigned.
• The disk status:
  Synchronized – This drive is in an array and is in optimal condition.
  OK – The drive is not in an array and is in optimal condition.
  FAIL – The drive has failed.
  Unrecognized – The drive contains unrecognized data. You must format the drive before it can be used.
  Inactive – This drive is in an array, but is currently not in use.

  Degraded – The array is accessible and there is no data loss; however, a disk has failed or is missing. Performance and reliability may be reduced. Replace the failed drive as soon as possible.
  Fail – The array is not accessible.
  Recovering – A degraded array is being repaired. The CTERA Edge Filer is currently synchronizing out-of-sync members of the array, and performance of the CTERA Edge Filer may be reduced. Once the recovery is finished, the array will return to optimal state.

Volumes – All volumes defined on the CTERA Edge Filer. For each volume:

• The volume name.

• The storage device on which the volume is located. Click on this link to edit the volume. See Managing Volumes for further details.
