Product: ArcGIS Monitor
Platform: Windows 2016 Standard
-> Site-> Collection-> Monitor Service-> Server-> Config-> [Sample Interval]
Function: Multiple Sample Intervals
Reason: Allow Servers to be monitored at Intervals appropriate to operational circumstances
Case: Monitor at - shorter intervals during production hours, shorter hours during maintenance hours
Example: 1 or 5 minute intervals during production. 15 or 30 or 60 minute intervals during maintenance.
Multiple Sample Intervals (at least two) allow monitoring to match operational circumstances and variable SLAs.
Good idea but I believe you can achieve the same results by adding two counters of the same ArcGIS Site and configure it accordingly.
