CC-SG Disk Monitoring

If CC-SG disk space exhaustion in one or more file systems occurs, it may negatively impact your operation and even results in the loss of some engineering data. Therefore, you should monitor the CC-SG disk usage and take corrective actions to prevent or resolve potential issues. You may perform the disk monitoring either via the Diagnostic Console or via the Web browser. If you are a sophisticated user, you may use the gkrellm Remote Monitoring.

Important: For CC-SG units in a cluster configuration, you must monitor both CC-SG units.

To monitor the disk space via the Diagnostic Console

1. Log into the Diagnostic Console and invoke the Disk Status screen.
2. Check the disk-related information and take actions when necessary.
   • Both RAID partitions should display as [UU] instead of [U_] or [_U]. Otherwise, a disk failure is indicated and you must contact Raritan Technical Support.
   • None of the file systems' Use% values (the fifth column on the screen) should be greater than 50%. Different file systems contain different data and corrective actions are also different.

     

     File system	Data	Corrective action
     /sg/DB	CC-SG database	Contact Raritan Technical Support
     /opt	CC-SG backups and snapshots	Save any new snapshot files on a remote client PC. See Take a System Snapshot for the retrieval procedure. Enter the System Snapshot menu. Select Pre-Clean-up SNAP area. Select Pre-Clean-up UPLOAD area. Deselect SNAP. Deselect Package & Export. Click or select Submit. If the space problem remains, use the Admin Client to connect to CC-SG, upload CC-SG backups to a client PC and then remove them from the CC-SG.
     /var	Log files and system upgrades	Contact Raritan Technical Support
     /tmp	Scratch area (used by snapshots)	Enter the System Snapshot menu. Deselect SNAP. Deselect Package & Export. Select Clean-up /tmp. Click or select Submit.

To monitor the disk space via web browser

This method applies only to CC-SG release 4.0 or later. You must enable Web Status Console-related options in Diagnostic Console before you can monitor the disk space using the web browser. See Access Status Console via Web Browser.

1. Using a supported Internet browser, type this URL: http(s)://<IP_address>/status/ where <IP_address> is the IP address of the CC-SG. Note the forward slash (/) following /status is mandatory. For example, https://10.20.3.30/status/.
2. A status page opens. This page contains the same information as the Status Console.
3. Click CC-SG Monitors under Evaluation at the bottom of the page.
4. Check the disk-related information and take actions when necessary. See the previous section for details.

Note: For file system problems that are not mentioned in this section, or when the corrective actions you take cannot resolve the problems, contact Raritan Technical Support for assistance.
