The error message "Hierarchy filter is not supported as filter" indicates that the filtering method you are trying to use in Dynatrace is not supported for creating the metric in the way you are attempting.
To count the number of exceptions from a request to a specific service in Dynatrace, you can use other filtering options or alternative approaches:
1. **Service Filter:**
- Instead of using a hierarchy filter, try using a service filter. You can filter the requests by the specific service you're interested in, and then count the exceptions associated with that service.
2. **Custom Metric:**
- Create a custom metric for exceptions specific to the service. You can use Dynatrace's custom metric capabilities to instrument your code to capture exceptions and increment a counter metric whenever an exception occurs in the context of the service you're interested in.
3. **Alerting Rules:**
- You can create alerting rules in Dynatrace based on exceptions. Define alerting rules to trigger notifications or actions when exceptions exceed a certain threshold for the specific service.
4. **Custom Scripting and API:**
- If the built-in metric creation options do not meet your requirements, you can also consider using custom scripting and Dynatrace's API to extract and count exceptions from the service in a more customized way.
5. **Dynatrace Support:**
- If you're still facing difficulties or if your use case is complex, consider reaching out to Dynatrace support for specific guidance on how to achieve your metric counting goals.
The exact approach you choose will depend on your specific use case and requirements. If you can provide more details about your setup and requirements, I can offer more specific guidance on which approach might be most suitable for your situation.
