Free MegaBytes (LDldFreeMegabytes)


Displays the amount of unused space on the disk drive in megabytes (MB).

Note

The Free MegaBytes attribute in BMC ProactiveNet Performance Management is referred as the LDldFreeMegabytes parameter in BMC PATROL.

If the /PSX_P4WinSrvs/PWK_PKMforMSWinOS_config/LogicalDiskMonitoring/NonAggregateParamValue variable is set to 1, this parameter will not take the value of the mount points on that particular drive instance.

Applications that write to drives with limited space can cause operating system stress and possible failures. By default, PATROL takes no action when this parameter displays an alarm or warning.

Recommendations

For drives larger than 1 GB: If this parameter falls below the number of megabytes that you have chosen for your system, you should take some action to provide more free disk space.
To provide more free disk space:

  • Delete or move duplicate or unneeded files from the drive. Consider archiving the data before taking these actions.
  • Back up the files on the drive, replace the drive with a larger capacity drive, and restore the files to the new drive.

For drives that are 1 gigabyte (GB) or smaller: Consider using the LDldFreeSpacePercent (percentage of free space on the logical disk) parameter rather than the LdldFreeMegabytes parameter. The LdldFreeSpacePercent parameter notifies you when its value falls below 10% (warning) and 5% (alarm).

Thresholds for alarms and warnings

No default thresholds have been set for this parameter. The Baselining Overview topic may help you determine appropriate settings for your system.
