Hi,

I need to configure Adaptive Thresholds based on time.

There are different policy types: Standard deviation, quantile, and range.

I need information about each of them and the best way for configuring them.

Can you help me please?
Thank you very much.

Hi... I'm in the middle of writing/publishing several multi-part blogs on ITSI alerting and thresholding best practices... I'll have a blog published (hopefully in the next couple of months) which specifically addresses adaptive thresholding, but in the meantime, I'd love to have you read the first of the series to see if some of your questions and needs are addressed...

alt textI was looking for some more info on this as well. Maybe a blog post from Splunk covering few scenarios in ITSI for adaptive thresholds and best practices?

I expect I will be doing a lot trial and error since there's not much documentation other than how to select from the dropdown.
http://docs.splunk.com/Documentation/ITSI/2.5.2/Configure/HowtocreateKPIsearches

From my brief testing on something like order count quantile and range gave me the same results whereas std deviation didn't seem suitable for something that could go to a zero value and still be ok.

I'm going to also test these 3 with other things like CPU where I think std deviation may work ok.

Some wikipedia info:

https://en.wikipedia.org/wiki/Standard_deviation
https://en.wikipedia.org/wiki/Range_(statistics)
