Monitoring WhatsUp Gold server disk usage

WhatsUp Gold must be set to monitor its own disk usage to avoid disk exhaustion. Over time, accumulated log files and other data can fill up a disk. Disk exhaustion causes services to run slowly and eventually fail in which case, WhatsUp Gold may drop incoming device data and log messages.

You can avoid this condition by creating and adding a performance monitor for the systems (the devices) hosting the WhatsUp Gold components. This includes primary and secondary WhatsUp Gold servers, additional pollers, and the WhatsUp Gold database server system if it is on a machine that is separate from the WhatsUp Gold secondary machine.

You must also create an Alert Center threshold to notify a Windows administrator who can intervene and offload older collected data to an archive database.

To monitor and alert when disk utilization exceeds 90%:

Establish SNMPv3 credentials to interact with each of the WhatsUp Gold server machines.
Create the following Alert Center thresholds as applicable:
- WhatsUp Gold Primary Server Disk Utilization Exceeds 90%
- WhatsUp Gold Secondary Server Disk Utilization Exceeds 90%
- WhatsUp Gold Database Server Disk Utilization Exceeds 90%
  For more information, see Configuring Alert Center thresholds.
Add the Global Disk Utilization Monitor to each system in your WhatsUp Gold deployment. This monitor is available in the performance monitor section of device properties when you right-click the device in the device list. For more information, see Working with Performance Monitors.

Nightly rollups of log files and collected device data for each day facilitate offloading the oldest data to an archive for safekeeping. For more information, see Program Options - Report Data. If you receive an alert that a WhatsUp Gold server is exceeding the 90% disk usage threshold, offload some of the oldest data to an archive for safekeeping.
