ECS fargate PaaS agent host name detection

[thuang09]

Hi there,

I am running PaaS agent (runtime injection through /api/v1/deployment/installer/agent/unix/paas/latest) on ECS Fargate container. The hostname detected is reported as ip-1-2-3-4.ec2.internal and the host has property "Cloud=EC2" attached.

Based on the sample case provided on Dynatrace KB, the hostname is supposed to be detected as ECS task name.

Would you please advise what could be the problem?

Thanks!

@thuang09 do you have the KB Link? I'm curious if they forgot to include a step for a Host Rename action. You can set automatic rules to rename the hosts as you see fit.

@ChadTurner The root cause is on container "ReadOnlyRootFileSystem". Dynatrace agent requires R/W access to temporary folder for ECS meta data processing . Issue fixed by binding a R/W volume to the container for such access.

Thanks!
