Agent Connectivity Problems
We have our windows based web site hosted on 4 servers. Although we can see on the monitoring/infrastructure dashboard details and basic performance metrics about the servers only one of the four machines is showing us purepaths/transactions. Looking closer at the agent status we see the message:
The Agent is not correctly working because there's a shared memory related problem (details see logs)
Although the agent is connected we are not getting transactions captured when checking the purepaths. Any advice on this status message will be great. Where do we see the correct logs, is it within the System Information>System Profile>app profile log
Thanks
no, you have to look into the agent log files, which are located in the system information dashlet under:
<server_name> - "connected systems" - <collector_name> - "connected systems" - <agent_name>

Thank you Christian, I can see the agent logs now. I think I opened the correct log and see the details below similar to the general memory problem I saw on the UI. Any additional advice on the details below will be greatly appreciated.

mhm, it's interesting why the shared memory file should be "F:\Program Files (x86)\dynaTrace2\dynaTrace Agent 5.5.0\agent\conf", which is usually just the config directory.
could you please check the following:
- look into the file "F:\Program Files (x86)\dynaTrace2\dynaTrace Agent 5.5.0\agent\conf\dtwsagent.ini". is there a value to "SharedMemoryFileName" or is it commented out?
- what are the permissions on the "F:\Program Files (x86)\dynaTrace2\dynaTrace Agent 5.5.0\agent\conf" folder? does the user which is running the web server processes have permissions to read files in this folder? it's best practice to set this folder and all files in it to be readable by all users.
HTH,
Christian
