Licencing - Memory Alert

[kasdev]

Hello.

I've recently figured out that my hosts' memory size increased which caused my licence consumption increased. Normally hosts' memory sizes were 16gb but somehow it increased up to 128gb. I will share with you a visual.

above you see a conclusion of a script which shows us HU before and after hosts' memory size changed so HU changed.

My question is:

Is there a way that i can create an alert when hosts memory size increased which causes my HU increased?

Hi,

You can create a metric event when that metric is higher than X value.

Best regards

You can easily find them using the delta transformation in Data Explorer:

builtin:host.mem.total:splitBy("dt.entity.host"):auto:delta:filter(series(auto,gt(0)))

like this? 

i think this dashboard gives me host memories. but it does not give me alerts if hosts' memory sizes change or cross the limits i can create. 

i am still confused how can i create alert on this dashboard.

[Julius_Loman]

Please paste the metric selector I provided into advanced mode. :delta transformation is the important point.

hello again.

i did what you said end now i see:

but i am still not sure if this dashboard gives me ALERTS if hosts' memory sizes change.

how can i create alerts if a host's memory changes?

@kasdev,

You can create a "Metric Event" for it. Select an appropriate Event type, and then alert on it.

@kasdev , to create the metric event, you can use the following fields

Thank you very much. But i've last question 🙂

do you have an idea if this solution consumes DDU ? 

[Julius_Loman]

@kasdev No, it does not. It's based on the built-in metrics.

[AntonioSousa]

It doesn't even consume DDUs per custom Davis events, as it doesn't meet the requirements explained in https://docs.dynatrace.com/docs/manage/subscriptions-and-licensing/monitoring-consumption-classic/da...
