Finding distributed traces based on hostname

Hello!

Can we filter distributed traces based on the calling host?

You can filter by adding called by and then by the service instance:

It helps if you have your service instances properly named. Other solution could be use of request attributes in the request on the calling service if you have some which can help you identify the instance / host.

Thank you for your reply Julius.

Your advise is useful but mostly when you know what you are searching for. Currently, we are looking for a more generic search such as "List the requests originating from a specific host per service instance".

It would be helpful if this could be done on the multidimensional analysis tool but for now it is not an option. Any idea?

It depends. With traces in grail this is simple. For distributed traces classic or Dynatrace Managed this gets more challenging. I recommend having the service instances named and identified properly or look up the instance id and then using it in the filter. It's unfortunately not straightforward nor simple.

I recommend looking at the backtrace feature too. Maybe you can triage and filter from there?

Thanks @Julius_Loman

Just as expected, only the "called by" attribute can help at the moment. We are working with managed so no GRAIL at the moment.

Anyway, thank you for your instructions.
