Ipswitch WhatsUp Gold User Guide
Reducing performance monitors
This option examines the number of performance monitors applied to devices in WhatsUp
Gold. There are several issues that can arise if you have too many performance monitors
assigned to your WhatsUp Gold devices.
More database space is needed to store the monitor configuration as well as the data
collected from polling.
Increased CPU and memory usage from both the WhatsUp Gold and SQL processes
during polling.
Increased network resource usage during polling, increasing the change for packet
loss and latency issues.
Polling delays; for example, devices not being polled on schedule because there are
other monitors in the task queue.
Consider reducing the number of Performance Monitors applied to your WhatsUp devices or
increasing the polling interval for less-critical performance monitors.
WhatsUp discovery service is down
If the WhatsUp Health Threshold reports that the WhatsUp discovery service is down, you
need to restart the Ipswitch Discovery service. This service must be running at all times to
allow devices to be discovered and for scheduled discoveries run. If this service has stopped
unexpectedly, it may have crashed. To assist Technical Support in locating the source of the
failure, please perform the following task:
1 Open the Windows Event Viewer from Administrative Tools or the Computer
Management console.
2 Locate an Error entry with DiscoveryService.exe listed as the Source.
3 Use the Technical Support request form on the WhatsUp Gold web site
(http://www.whatsupgold.com/support/technical-support.aspx)
(http://www.whatsupgold.com/support/technical-support.aspx) to submit the details of
this error, along with the version of Windows installed on the WhatsUp computer,
including any service pack and CPU architecture (32-bit or 64-bit). Please also include
the version of WhatsUp Gold installed. You can find version information on the WhatsUp
Gold About box (on the WhatsUp Gold console at Help > About).
WhatsUp web service SQL queries exceed threshold
If the WhatsUp Health Threshold reports that the WhatsUp web service SQL queries have
exceeded the threshold number, there are several steps you can take to resolve the problem,
dependent on the SQL database you are using.
