Dear Dynatrace Gurus, before you say move to the new dasboards with DQL, I would like t keep the old classical dashboards for now. I have a couple of questions, I hope someone can help me? 1. I need to modify this classical dashboard query to display two important metrics (see below), In this I use tech.generic.cpu.usage builtin:tech.generic.cpu.usage:filter(eq(“dt.entity.process\_group\_instance”,PROCESS\_GROUP\_INSTANCE-2F6198CAE881F38A)):splitBy(“dt.entity.process\_group\_instance”):max 1. Process Group → Tecnology Specific Metrics → GC Time 2. Process Group → Tecnology Specific Metrics → GC Time Where can I find the documentation for tech.generic.?.? (use to obtain more out of the box metrics) 2. I have a dashboard that uses the same query above, but if the process is down it says no data is available and you would see an empty no name chart. How can I show on the same dashboard to say process is down and not available and may be show as red - like Availability button. Can someone help? I appreciate your support. Marwan… ---

Correction: 2. Process Group → Tecnology Specific Metrics → Response Time ---

The doc for the tech generic metrics is here: [Built-in classic metrics — Dynatrace Docs](https://docs.dynatrace.com/docs/observe-and-explore/metrics/built-in-metrics#generic) You can use the metric builtin:tech.generic.count to show if your process is Up (\>1) or down (0). Try the single value visualization and mark 0 as red, \>1 as green. ---

I used this for the CPU of that process like this builtin:tech.generic.cpu.usage:filter(eq("dt.entity.process\_group\_ins tance",PROCESS\_GROUP\_INSTANCE-98CB935943677AB7)):splitBy(“dt.entity.process\_group\_instance”):max Then If I use the single count with the metric that you recomened builtin:tech.generic.count:filter(eq(“dt.entity.process\_group\_instance”,PROCESS\_GROUP\_INSTANCE-98CB935943677AB7)):splitBy(“dt.entity.process\_group\_instance”) I get this error The dimension key `dt.entity.process_group_instance` has been referenced, but the metric has no such key. If I remove the split builtin:tech.generic.count:filter(eq(“dt.entity.process\_group\_instance”,PROCESS\_GROUP\_INSTANCE-98CB935943677AB7)) I get this error The dimension key `dt.entity.process_group_instance` has been referenced, but the metric has no such key. I need to monior availability this particular process instance PROCESS\_GROUP\_INSTANCE-98CB935943677AB7 Thanks for any feedback ---

How many Process Instances you do have for this process Process Group? This metric will look for Process Instances in your Process Group. The Process Group Instance is not a valid dimension for this metric. You should use the Process Group as filter/split by. ---

There are two instances one each host and the code above works like a charm. I filter by host and technology to find availability of each process in one dashboard. Do you another way to do this?
