The Disk Space Monitor, displays the amount of free disk space for recording and can send warnings when disk space goes below a certain threshold of days capacity.

To configure the Disk Space Monitor:

Navigate to Settings > Configuration > Maintenance > Disk Space Monitor.

  1. To send warnings:
    • By email select the Notify by email checkbox
    • By SNMP select the Notify by SNMP checkbox
     
  2. Type email addresses in the Email addresses field separated by commas.
  3. Type the number of days warning that the system gives before recording space runs out in the Warn when space will last (days). The system sends warning messages when it predicts that only this number of days are remaining at the present rate of consumption of disk space. For example:

"Warning: Volume /dev/sda1 (/mnt/disk1) is running out of space, estimated time remaining is 3.5 day(s)."

Volume /dev/sda1 (/mnt/disk1): 27.5 GB used, 4.5 GB free space."

  1. If Notify by SNMP is selected type a name for the SNMP trap destination
  2. If Notify by SNMP is selected, then select the SNMP version from the drop-down list
  3. Click Save configuration

Viewing Disk Usage in the Disk Space Monitor

To view Disk Usage in the Disk space monitor:

Navigate to Settings > Disk Usage.

The Disk space monitor displays the disk usage if there are more than twenty four hours of data available.

The disk monitor displays any writable disk partitions and calculates the estimated remaining time in days, based on the average daily usage of the last seven days. If the disk monitor has a full week of data then the estimate is more accurate than if the disk monitor only has a little data.
