Process detection and Data Explorer

[deni]

I have the following case:

I have 2 nodes with one agent on each of them. I have 1 process that runs on node 1, but if node 1 is restarted it will run on node 2. Dynatrace detects this process like 2 processes in 1 process group and if I want to see the process availability % in Data explorer it shows 50% availability.  I wait about 3 hours and this didn't change.

Is there some timeout after which the process will not be monitored anymore? Is there some configuration about this? I saw that the process disappears from Hosts view after about 5 minutes inactivity.

Hi,

Do you have some screenshot for undestanding better?

Hi,

and this is the same split by process

In the Technologies and Processes it shows 1 process instance.

I stopped the process on ariel and started it on earth about 3 hours ago. And all views are for the last 10  minutes.

Hi,

Do you need to create some alert or which is target goal?

Best regards

Hi,
No, for now I'm trying to understand how Data Explorer works. I expected that if I want to check the process availability % in last 10 minutes, since there is only one process in this process group in the last 10 minutes to see 100% availability. Instead of that I see 50% availability, because the Data Explorer still "remember" that a long time ago (3-4-5 hours) there was a process with the same name on some other host. So I want to understand where is the mistake in my logic?

Thanks!

Regards, Deni

Hi @deni , how are you? 🙂
Did you maybe solve this issue?

Hi @GosiaMurawska ,

No, it still stays opened ...

I see the same behavior on the demo environment.  Since the metric used is:builtin:pgi.availability, my best guess is that by default the 72 hours is used that also applies for the smartscape topology. But perhaps we can get someone from dynatrace to confirm this.

I’ll test it, but it would be great if this could also be added to the official documentation.

Thanks 🙂

I'll contact the doc team 🙂
