I'm using Cloud Instance and all the version are the latest. NOTE: This is a trail version hosted on AWS. We are using external application --\>Gerrit and we would like to know how to use the Elastic APM to monitor the application which is not built by us. Can elastic run APM on applications which are not developed by the company and only hosted by us???? The documentation states the following but when i do it it simpley fails to start the application [https://prodtest.kb.europe-west3.gcp.cloud.es.io:9243/app/home#/tutorial/apm](https://prodtest.kb.europe-west3.gcp.cloud.es.io:9243/app/home#/tutorial/apm) ```auto ************* [root@awsmblx108as602 bin]# java -javaagent:/tmp/elastic-apm-agent-1.26.0.jar \ > -Delastic.apm.service_name=gerrit \ > -Delastic.apm.server_urls=https://e8544a56748c4b109e421b4b5da78319.apm.europe-west3.gcp.cloud.es.io:443 \ > -Delastic.apm.secret_token=kN8ZVOd99TDcRMSWqm \ > -Delastic.apm.environment=production \ > -Delastic.apm.application_packages=org.example \ > -jar /data/gerrit/bin/gerrit.war WARNING: sun.reflect.Reflection.getCallerClass is not supported.

from the look of the error you pasted there, you are failing to add an argument to the gerrit startup, ie it is saying that your startup command needs to be java -javagent... ... -jar /data/gerrit/bin/gerrit.war COMMAND where you need to replace COMMAND with one of those gerrit commands listed (like `daemon`). Gerrit is terminating because you haven't given it an argument. Please reset your secret token, as this a public forum so the token you've pasted is now public ---

We start and stop gerrit as a service.............How do we use that to monitor gerrit using elastic and APM??? Also some of our applications are docker based so how do we use that to integrate elastic APM with docker...........For ex: docker compose up and docker compose down??? ---

systemctl stop gerrit.service systemctl start gerrit.service Also, does it inject anything. Manually if we were to start gerrit we simply run the below command. /data/gerrit/bin/gerrit.sh start /data/gerrit/bin/gerrit.sh stop ---

In this case, you have several options, for example - edit your `gerrit.sh` script so that the command line running the app (`... -jar /data/gerrit/bin/gerrit.war COMMAND`) includes those additional command line arguments (`javaagent` and the config options provided as system properties like the `-Delastic.apm.XXX` ones in your example above). - edit your `Dockerfile` so that the agent and configs are provided as environment variables: - Use `ENV JAVA_TOOL_OPTIONS=-javaagent:/path/to/elastic-apm-gent.jar` for the agent attachment - Use `ENV ELASTIC_APM_XXX=` for config options, e.g. `ENV ELASTIC_APM_SERVER_URLS=https://e8544a56748c4b109e421b4b5da78319.apm.europe-west3.gcp.cloud.es.io:443` Either way, you will have to edit your Dockerfile so that it downloads the agent from maven central (e.g. [Central Repository: co/elastic/apm/elastic-apm-agent/1.26.0](https://repo1.maven.org/maven2/co/elastic/apm/elastic-apm-agent/1.26.0/)) and store it in your Docker image so that your `-javaagent` argument refers to a local location within the container. Lastly, you will have to setup your container so that the APM Server is accessible to it. I hope this helps. Good luck! ---
