Issues Capturing ArcGIS Server Service in Trends on Geocortex Analytics

We are experiencing issues capturing ArcGIS Server Service in the server trends for CPU time and Disk IO. It was being captured for a time but has since stopped. I don't believe we have made any changes to the configuration or settings on our end that would have caused issues. When reviewing the logs to identify any issues, I found in Analytics Resource Collector an error related to the server, it appears every hour. I am not entirely sure if this error correlates to the information not being captured in analytics trends.

I have check that the log files are being generated on the server and have ran tests with different time intervals to query the logs on ArcGIS manager/admin sites, the logs are returned within a few seconds with no issues. This is our production server so there is more activity. Log settings are set to verbose. Also to note, this server is being monitored in analytics through remote monitoring (agentless).

Any ideas on what might be causing this error and if it is associated with analytics server trends not capturing the ArcGIS Server Service information?

Geocortex Analytics version 1.7 and ArcGIS Server version 10.4.1

We know Geocortex Analytics is deprecated and are making plans to migrate our environment to newer versions, but any help is appreciated.

Thanks.
