Monitoring Your Cloud Storage Gateway

The cloud storage gateway comes with the following monitoring tools:

• Status dashboard. See below.

• Front-panel LEDs.

• S.M.A.R.T. drive testing. See Testing Hard Drives.

• Drive diagnostics. See Checking Drive Diagnostics.

• SNMP monitoring. See Using SNMP Monitoring.

• Cloud Storage Gateway logs. See Configuring Logging.

The Cloud Storage Gateway dashboard provides an overview of the gateway's current status, including the following:

• Disk drive and volume information

• Resource utilization information

• Fan activity and the CPU temperature for C-Series Cloud Storage Gateways

• Information regarding scheduled backups

In addition, it provides shortcuts to configuring arrays, drives, and volumes.

• In the Configuration tab, select Main > Dashboard.

All disk drives installed on the cloud storage gateway. For each drive:

• The disk type. Click this link to view additional information about the drive. For further information, see Checking Drive Diagnostics.

• The disk size in GB. Note that you may notice a discrepancy between the disk capacity stated on the disk's packaging and the disk capacity displayed in the cloud storage gateway Dashboard. This difference is due to the fact that vendors define 1 GB as 1 billion (109) bytes, while computers define 1 GB as 230 bytes.

• 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.

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.

Rebuilding – This drive is in an array that is currently being rebuilt.

All arrays defined on the cloud storage gateway. For each array:

• The array name and, for a C-Series gateway, the RAID type. You can click this link to edit the array. See Modifying Arrays for more details.)

• The array size in GB.

• The array status:

Degraded – The array is accessible and there is no data loss; however, a disk is failed or missing and, for a C-Series gateway, the array type is RAID1 (Mirroring). Performance and reliability may be reduced. Replace the failed drive as soon as possible.

Recovering – A degraded array is being repaired. The cloud storage gateway is currently synchronizing out-of-sync members of the array, and performance of the cloud storage gateway may be reduced. Once the recovery is finished, the array will return to optimal state.

All volumes defined on the cloud storage gateway. For each volume:

• The volume name.

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

• The volume's status in the format: Mode [Status]. The mode can be Online or Offline. The status can be:

Read only – The file system is incompatible with current firmware.

Recovering – The file system is being recovered after a non-clean shutdown.

Mounting – Routine cleanup is being performed after a non-clean shutdown.

Converting – The volume is being converted (from EXT3 to NEXT3, or the opposite).

Checking Quota – The volume's storage quotas are being recalculated.

• A bar representing of the percentage of the volume currently in use, followed by the volume size in GB, followed by the percentage of the volume currently in use.

• CPU fan activity, reported as a percentage of the fan’s maximum RPM capability.
