ArcGIS Monitor is unable to receive metrics from ArcGIS Server despite successful registration

Description

In some instances, after successfully registering ArcGIS Server as a component in ArcGIS Monitor, no metric data displays for the associated component in ArcGIS Monitor. The ArcGIS Server component appears correctly in the ArcGIS Monitor interface, services are listed, and the observer status is nominal. However, the elements show a "No data available" message, indicating that metric collection is not functioning as expected.

Additionally, when running the ArcGIS Server metric observer in ArcGIS Monitor, the process fails and returns the following error message:

Error:
Failed to read ArcGIS Server usage report

Cause

The ArcGIS Server usage report takes longer than the default request timeout of 30 seconds to generate, causing the metrics observer to fail.
