Hi,

So I am working on an extension that sends an alert based on the result of a powershell script. Now, if I wanted to create object/classes and then bind the alert to those, how would I go about doing that? For example, I run a powershell script that checks something on an sql server, is there a way to identify that sql server that isn’t through the entity selector?

Thanks,

Benji\_Dynatrace

Hi,

If you use [metric scripting integration](https://docs.dynatrace.com/docs/shortlink/pipe-metric-ingestion) it is comes with OneAgent, already pointing to your host.

Best regards

You can use metric line enrichment for this.

Option 1: If you know the process id of the process and you add, for example,&nbsp;`dt.process.pid=12345` to the metric line it will automatically be exchanged for `dt.entity.process_group_instance=PROCESS_GROUP_INSTANCE-D337020E5CAE4F0F,dt.entity.process_group=PROCESS_GROUP-D337020E5CAE4F0D`.

Option 2: If you know the tech rule of the process ([Process group detection — Dynatrace Docs](https://docs.dynatrace.com/docs/platform-modules/infrastructure-monitoring/process-groups/configuration/pg-detection)) and you add, for example,&nbsp;`dt.techrule.id=zoomtech` as a dimension, it will automatically be exchanged for the above entity dimensions.
