Is there anything special in your setup? nothing, separate indexes for transactions, spans, metrics, errors etc made on apm server, also we drop unsampled transactions via processors on apm server to lower throughput
Description of the problem including expected versus actual behavior. Please include screenshots (if relevant):
We are having a weird issue with transaction count. We have several services (tomcat apps mostly) which connect to each other via various endpoints. Somehow we noticed that spans from transaction on service A affect transactions count on service B. If we change sample rate for service A 0.01>0.001 we will see the drop of transactions for service A, but also we will see the drop for service B.
Also in some cases the drop for the service is not equal to sample rate setting change (example we change frame rate 1 > 0.1 and see 40000tpm > 25000tpm change which is not relevant)
We believe that this happens because transactions from "related" services are somehow summed up.
Please clarify this situation, because right now we cannot know for sure how much tpm exactly we get for each app.
Steps to reproduce:
Errors in browser console (if relevant):
