Have you filed a ticket with support? Based on a quick glance at the exception here, I suspect that this results from an agent issue that is fixed in 21.5 of the agent, but a more detailed support investigation would be required to be sure. Where is this exception logged to?

Peter_Holditch · ‎02-09-2021

Machindra, The facility to allow OpenTelemetry traces to be imported into AppDynamics is currently under development (I am product manager for this effort) It would be extremely useful for me to have additional context around your request, please can you tell me (either via the IDEA thread, or in a direct message if you prefer) 1. What is the application that produces traces and metrics? It it home-grown or some 3rd party product? 2. What use cases do you want to enable by ingesting trace data? 2a. Monitoring & Alerting on application response time 2b. Troubleshooting application behaviour based on analysis of traces 2c. Other (please give details) 3. What is the relative importance of these use cases to you? 4. Does the application that produces traces communicate with applications or systems that you already have instrumented with ApDynamics agents? What are these systems? Would you value end to end troubleshooting? Warm regards, Peter

Ahmed, Transaction analytics does not sample data gathered by MIDCs, but should collect a value for every invocation. Things to check: Are you sure that the method your MIDC is placed on is called for absolutely every transaction invocation? Do you see any messages in the agent log indicating there may be problems collecting the data? For troubleshooting beyond that, I would advise you to work with customer support via a help ticket. Warm regards, Peter

Gabor, My bad, I missed the local-to-the-try-catch-block constructed Transaction object when I looked at your code. From your latest comments, it sounds as if this is working as expected. The 1st time your entry is called within a new process, the BT will register with the controller. Once that is done, subsequent invocations handled in the same process will be measured, and as those measurements are reported by the agent (once per minute) the data will become visible in the controller. I suspect you eventually amassed enough post-registration invocations and elapsed time for that to happen. Warm regards, Peter

Peter_Holditch · ‎01-04-2021

Hm, OK. Your code does. not show you calling endTransaction, but you do mention that in the subject. Are you certain your code is calling endTransaction? Also, how many times in the transaction you have instrumented being executed? Do you see it referenced if you remove the (default) filter for Transactions with performance data?

Peter_Holditch · ‎01-04-2021

2 thing to check: Are there any error or informational messages written in the agent log? Have you hit the node or application level BT limit? Warm regards, Peter

Peter_Holditch · ‎12-09-2020

Ahmed, Business transactions are identified by BT name and originating tier, so you will get one transaction per name per tier. What is your underlying motivation for splitting the nodes into different tiers? How do the loads differ? Warm regards, Peter

Peter_Holditch · ‎06-02-2020

The issue here is that "feed" is a valid hexadecimal number... If you're sure that your application never needs to interpret 'feed' as anything other than the word feed, you should be able to manage this situation with rule priorities. The higher priority rule should match "ends with hendelser/feed" and the lower priority one should be your regex match. That way, exact feed matches will never hit the second rule. The documentation shows you how to set rule priorites. Warm regards, Peter

Do you have any output at all from the glassfish startup? When you say "the agent /opt/appdynamics/appagent/javaagent.jar is unzipped inside the container where glassfish is running" do you mean that the only file in the container is javaagent.jar? If so, that is the root cause of your issue. You need the entire agent directory structure as contained in the agent zip for the agent to function.

Peter_Holditch · ‎05-05-2020

Steven, A high level explanation is provided in the documentation: https://docs.appdynamics.com/display/PRO45/Java+Agent+Directory+Structure Warm regards, Peter

Peter_Holditch · ‎03-25-2020

Is the server hosted in a container? If so, you may have trouble with entropy. Try putting -Dappdynamics.low.entropy=true on the JVM command line. If that does not help, can you post a thread dump taken from the JVM during startup? Warm regards, Peter

Peter_Holditch · ‎03-17-2020

Rohde, Can I ask what kind of server-side projects you are developing using kotlin, and which frameworks you are using? Warm regards, Peter

Peter_Holditch · ‎03-10-2020

Mudassir, I will file a ticket to improve the documentation in this regard; the analytics agent requires java 1.8 or higher to run, as is mentioned here. (if a java application agent is reporting the data, the application JVM that sends the data to the analytics agent for processing can be any version supported by the java agent) Warm regards, Peter

Peter_Holditch · ‎03-10-2020

Kjell-Einar, It's at least implied in the documentation here Warm regards, Peter

Peter_Holditch · ‎03-09-2020

The exclusion will be actioned on the agent side, so the agent will ignore the excluded activity.

Peter_Holditch · ‎03-05-2020

Catherine, I'm delighted that got you going. If you have any suggestions as to how we could make this easier to find in the documentation, please let me know. From the inside, it's easy to take too much for granted. What search terms did you try to use to find this? Where would you expect to see it? Warm, regards, Peter

Peter_Holditch · ‎03-03-2020

John, You are correct that this is the method used to calculate this metric. The net result is that it measures the CPU consumption as a percentage of the resources that the JVM user declared were allocated to the JVM, a measure that is useful to some customers, so just changing the way it is calculated is problematic. It is possible to track the process CPU consumption vs the resources of the entire machine using the SIM agent Does this latter method address your needs? Warm regards, Peter

Peter_Holditch · ‎03-03-2020

Catherine, You should create an exit call object and obtain the outgoing correlation header from that, as shown in the code sample in the documentation here: https://docs.appdynamics.com/display/PRO45/.Manual+Tracer+Instrumentation+v4.5.x#id-.ManualTracerInstrumentationv4.5.x-exit I pasted the relevant section below: //Define the createExitCall method to obtain an exitCall object. ExitCall exitCall = transaction.createExitCall(callType, identifyingProperties); outgoingHeader = exitCall.getCorrelationHeader(); exitCall.start(); try { // Tracer.APPDYNAMICS_TRANSACTION_CORRELATION_HEADER_KEY is the name of the header that should be set if (outgoingHeader != null) { conn.setRequestProperty(Tracer.APPDYNAMICS_TRANSACTION_CORRELATION_HEADER_KEY, outgoingHeader); // set the correlation header on an HttpURLConnection } // Make the exit call here } finally { exitCall.stop(); } }

Peter_Holditch · ‎02-27-2020

Catherine, It appears that the value of the correlation header you are trying to consume on input is "com.appdynamics.serverless.tracers.aws.correlation.CorrelationHeader" That is definitely not a valid header, where did you obtain it from? To give you an idea of what you should be expecting to see, an example of a valid header is: appId=4113*ctrlguid=1539290818*acctguid=e2c8a068-be66-46a4-a0d3-aeff5f18ecc9*btid=532007*guid=efbe5515-1e93-496c-9f53-47c1640069e73*ts=34869499416608*cidfrom=7500*unresolvedexitid=139411*exitguid=40*cidto={[UNRESOLVED][139411]}*etypeorder=HTTP You should get a string of that form returned to you when you call getCorrelationHeader() on the ExitCall object you created in the upstream lambda. Warm regards, Peter

Peter_Holditch · ‎02-26-2020

That is odd. Can you post your JVM command line from ps -ef? Do you see any output from the agent written into the console window of the JVM as it starts?

Peter_Holditch · ‎02-24-2020

Anand, Business Transactions represent the end to end flow through an application architecture. They are named on entry and end to end timings are collected from each tier as they flow through. If I understand your question correctly, you are interested in the performance of the individual tiers as services, rather than (or maybe as well as?) the response time of the end to end BT, is that right? If so, you can use service endpoints to track the response times at a tier level, or (as you pointed out) split the services into separate AppDynamics applications and use cross BT correlation to get timing for each service. If this does not give you the information you seek, it would be very useful to understand more about what you are trying to achieve; there may be other ways to get what you want. Warm regards, Peter

Peter_Holditch · ‎02-14-2020

Kenn, As you suspect, the "Sun or JRockit" agent will work with any OpenJDK. Warm regards, Peter

Peter_Holditch · ‎02-13-2020

The 0% in that column indicates that the controller has not had any data reported to it from the agent represented by that row of the table for the whole of the selected time period. If you believe that agent was active during that time, you should check the agent logs to see if it is having trouble communicating with the controller. Warm regards, Peter

Peter_Holditch · ‎02-11-2020

Chris, The upgrade should proceed as documented. There should be no risk to the integrity of the historical data held in the controller. Warm regards, Peter
