Disk Latency Calculation Logic

Team , Do any one know how Dyntrace defines the standard threshold for Disk Latency. I saw instances where disk latency is less than 1 ms but still its saying its a problem however instances where more than 4 ms is also fine. Not able to understand the logic behind calculation. Can someone please explain . Thanks

Hello Adarsh,

The threshhold is basline based and out of the box breaches if disk read time and write time is higher than baselined ms in 3 out of 5 samples.

You can change this in Settings > Anomally Detection > Infrastructure. There you can find the settings for latency thresholds, verify your settings and set your custom values if the threshold is met for more than 3 samples it will raise a new problem alert.

Also you can set other rules specific to some disks:
