Incorrect CPU utilized Metric

AnasKanaan

Hi All,

 

We have recently installed a new fresh installation of arcgis monitor 2025.1 with the latest agent version 2025.1.1 in a brand new windows server 2025 data center edition. we have added a plenty of machines without having any issue. We have just now a problem with one of the machines in monitor as it seems that monitor collecting wrong cpu metrics. 

this is how it looks like in the machine 

and this is what Monitor reports 

as mentioned this Server has been created with the same settings and image as the other machines so it should not be a settings/rights issue

one more thing to mention that there was no issue with this machine when we had monitor 2024.1 version
Thanks in advance

Hello! I just had the pleasure of debugging this oddity in our server.
This happens because of the scheduled observers. The observer that grabs the system metrics is "Metrics - Host Windows". This (for us) is scheduled to occur every 1 minute. Other observers were also scheduled to occur every 1 minute.

In other words, the CPU Utilization is the exact CPU Usage % of when the "Metrics - Host Windows" observer runs. Since other observers run at this exact same time, it causes a brief CPU spike.

If you measure the CPU Spike from Performance Monitor, it exactly matches what Monitor Displays. 

Setting "Metrics - Host Windows" to check every 1 minute, and others at other times, creates a much more accurate chart. An example is below. 

In below example, system metrics are recorded every 1 minute while all other observers run every 5 minutes. You can see the dramatic spike that happens every 5 minutes.

 

 

To be honest, it's a pretty serious configuration flaw with observer scheduling. ESRI should include an option to where we can stagger the observer run times. Example, start running at "00:00:30" with a repeat interval of 1 minute. This would perfectly fix this problem!
