I'm using elastic cloud with two environments. On the test environment firewall rules are more liberal than on the production
we have integrated APM with C# application. I receive metrics only from test environment although I see in prod env registered service in APM dashboard but there is non in Transaction Type, Latency, Throughput and Failed transaction rate.
Both environments has open traffic to azure or google cloud endpoint on port 443.
But is 443 enough? Maybe I'm missing some additional port to open?
