Unable to get module info for expression

Question

Hi,

I'm getting below exception in logs for DotNet agent

info [native] Unable to get module info for expression_host_b00fa49823a048e68b75a01fe7cbeac3.dll. This is expected behavior on dynamic assemblies.
info [native] Profiler::ModuleLoadStarted(): Cannot process assembly expression_host_b00fa49823a048e68b75a01fe7cbeac3.dll. This is expected behavior on dynamic assemblies.

As I'm not PP for this agent.

Please suggest.

I have also observed below messages in Server logs

"Received events for agent (agentId: 7db5b561) that is not registered on server. Skipping events. Suppressing this warning for another 60000 ms."

Please suggest.

The second message indicates that you have an agent that is not known by the server. check your agents overview and dashlet and check if the agent is listed and if everything is "green". Try restarting that application and try again.

The "info" message you posted in the beginning is probably not related with you not seeing purepaths - it is the second message that indicates that all events from that agent are simply ignored because the server "doesnt know" this agent

So that means you get PurePaths in the beginning and then they stop? If that is the case I suggest you open a support ticket so that our engineers can have a look at it

hi Amol,

those INFO log messages do not indicate an error, just the fact that dynaTrace is currently not able to instrument dynamically in-memory-built assemblies, because there is no assembly on disk to be instrumented.

the WARNING log messages in the server log, however, should be investigated. so as Andi said, a support ticket with the server and agent logs would be best.

best, Christian
