One of our host in unhealthy. Details shown in DT is 'The memory health of host 'xxxxxxxx' is not ok. During the last 15 minutes this host reported 90% (or less) and 14 GB (or less) memory available'

Page faults per second is also very less. How to identify the reason for the host being unhealthy?

Hi Shobana,

This is difficult to analyze without a bit more specific information around what you are seeing. I can say that this is being marked as unhealthy due to Host anomaly detection settings in Dynatrace - this is set to open a problem is memory usage is 90% or above on windows, and 80% or above on Linux by default.

I recommend that you open a support ticket at a low severity level as this is an ask for additional assistance. You can open a support ticket here: https://www.dynatrace.com/support/

HTH,

Hayden
