As stated above, this usually indicates there is a network problem of some kind that is preventing the agent from connecting to the controller. You need to inspect the agent logs to diagnose the underlying issue.

From an AppDynamics perspective, the agent is fine with or without the presence of tomcat provided it gets the needed configuration. There is some documentation that talks about setting the agent up in a docker environment, which also points to the dockerfiles for some images we have created ourselves as examples. I hope this helps you arrive at the optimal configuration for your scenario.

Anjana, You should follow the instructions here. Spring boot appications are simply "standalone JVMs" from the perspective of AppDynamics configuration Warm regards, Peter

Kafka is only detected as a back-end with in-built agent configuration for its publish/subscribe mode (and that support was introduced in v4.4, so agent versions prior to that will not detect it without custom configuration) To detect its streaming mode, or to detect it in agent versions older than 4.4, you would need to create a custom exit point detection rule to match the API your application code is using.

Can you confirm: is your WebLogic server is running fine do you have any agent logs written under C:\AppServerAgent\ver4.x.y.z\logs? (these will be in a directory named after the AppD node name) Is there anything relating to the AppDynamics agent in the WebLogic boot log? I also note this is your WebLogic admin server you have instrumented. You are likely to get more interesting results from one of the managed servers where your app is running (unless this is a single server installation), although there is no reason that instrumenting the admin server should not work.

Can you try putting the -javaagent option at the start of the java options, rather than at the end?

Peter.Holditch

I had already included observations about point 2, but I did not make that very clear. I have updated my initial reply to make it clearer

Peter.Holditch

If the agent is reporting, it posts a value of 1 to its Availability metric (shown below in the metric browser for a node called WEB1_NODE in the ECommerce-Services tier of the ECommerce application) You can build health rules and alert on this at the node level, to get notification when a node is not reporting, or a the tier level to ensure each tier always has a certain minimum number of nodes. so if you see a 1 posted in that metric, you know the agent reported. For your cases 1 and 3, this wil be 0. For case 2, it is extremely unlikely that this metric would be 1 and absolutely no other data would be reported from the agent. That said, if it is 1 but you do not see Business Transaction activity that you expect within the instrumented node, then it is likely you are missing necessary entry points because your application is not running within a framework for which there is out of the box configuration. Warm regards, Peter

Brad, You need to mark the nodes as historical when they shutdown, using the agent property, or alternatively, there is a controller API you can call to mark nodes as historical. Once marked as historical, nodes are automatically purged Warm regards, Peter

Adrien, One of the new features of the 4.5 agent is the ability for it to work with controllers v4.4.1 or higher, so you will actually be fine in this scenario. Warm regards, Peter.
