Enable APM for springboot running on windows

Elastic Observability APM
1

Hello ,

I want to enable APM for java application running on tomcat server(windows). I’ve followed the steps mentioned in the setup-tomcat-windows . I have restarted the tomcat service running on windows but it was not working. I don’t know how to configure the environment variables in windows . I know we can set up these variables in tomcat9w.exe file but i don’t want to touch the any .exe file . Below is the output of setenv.bat present in C:/tomcat9/bin/

set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:C:\APM\elastic-apm-agent.jar
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.service_name=my-cool-service
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.server_url=https://apm-url
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.environment=Development
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.secret_token=secret_token

How can we load the environment variable by creating .bat file in tomcat ?

Hi !

First I would suggest to add quotes to be sure that the values are the ones we expect, you should also be able to use / instead of \ for file path to prevent any unexpected escape sequence.

set CATALINA_OPTS=""
set CATALINA_OPTS="%CATALINA_OPTS% -javaagent:C:/APM/lastic-apm-agent.jar"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.service_name=my-cool-service"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.server_url=https://apm-url"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.environment=Development"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.secret_token=secret_token"

Then, when tomcat starts, you should have some or all of those values printed in the tomcat log, do you have anything there ?

Also, if the `-javaagent` argument does not point to a valid instrumentation agent, the JVM will fail to start with an explicit log message.

Hi @Sylvain_Juge ,

I have modified setenv.bat , but still i am not able to get the data.


set CATALINA_OPTS=""
set CATALINA_OPTS="%CATALINA_OPTS% -javaagent:C:/APM/elastic-apm-agent.jar"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.service_name=my-cool-service"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.server_url=https://apm-server:443"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.environment=Development"
set CATALINA_OPTS="%CATALINA_OPTS% -Delastic.apm.secret_token=secret_token"

The first thing to check is that the JVM options like `-javaagent` are properly passed to the JVM.

To do that, the simplest solution is to use `jps -lv` with CLI, or to use `jconsole`, then look at the parameters of the running JVMs.

Then, once you are sure the parameters are properly added to the JVM arguments, in CLI you should try to run tomcat with `bin/catalina.bat run` , if everything is setup properly the `Starting Elastic APM` message will be visible in the logs on the standard output, with the agent version.

If everything is working as expected, the next step is to trigger a few HTTP requests on your application/tomcat server, then wait for the data to be sent to the APM backend. If there are any communication issues this should be visible in the standard output as well.

Hi @Sylvain_Juge ,

I run jps -lv command on cmd and below is the output

C:\Program Files\Java\jdk-25\bin>jps.exe -lv
880 jdk.jcmd/sun.tools.jps.Jps -Dapplication.home=C:\Program Files\Java\jdk-25 -Xms8m -Djdk.module.main=jdk.jcmd

I don’t know why it is not setting environment variables properly

Hello @Aniket_Pant

As per the documentation we do not see the quotes can that be causing issue? also in your output we do see the error :

Error: Could not find or load main class """ -javaagent:C:.APM.elastic-apm-agent.jar
Caused by: java.lang.ClassNotFoundException: """ -javaagent:C:.APM.elastic-apm-agent.jar

Could you please try without the quotes?

set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:C:/path/to/elastic-apm-agent-<version>.jar
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.service_name=my-cool-service
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.application_packages=org.example,org.another.example
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.server_url=http://127.0.0.1:8200

I think like below and see what is the error ?

set CATALINA_OPTS=
set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:C:/APM/elastic-apm-agent.jar
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.service_name=my-cool-service
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.server_url=https://50657be900ce43f2bd5c58af83ae4733.centralindia.azure.elastic-cloud.com:443
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.environment=Development
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.secret_token=gJYP5lxGQx0tnIniMH

Thanks!!

Hi @Tortoise ,

Now i am using below environment variable.

set CATALINA_OPTS=
set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:C:\APM\elastic-apm-agent.jar
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.service_name=Login_UI
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.server_url=https://50657be900ce43f2bd5c58af83ae4733.centralindia.azure.elastic-cloud.com:443
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.environment=Development
set CATALINA_OPTS=%CATALINA_OPTS% -Delastic.apm.secret_token=gJYP5lxGQx0tnIniMH

After that i run catalina.bat run and i got my application performance metrics.

Next i do close the terminal and run the tomcat as service from service.msc then it is not working and in the logs no apm related logs are showing and even apm variable is not there.

Hello @Aniket_Pant

As Sylvian suggested now you are able to see the below message in the log which means the configuration is correct :

2025-11-22 13:00:39,314 [main] INFO  co.elastic.apm.agent.configuration.StartupInfo - Starting Elastic APM 1.54.0 as Login_UI on Java 25.0.1 Runtime version: 25.0.1+8-LTS-27 VM version: 25.0.1+8-LTS-27 (Oracle Corporation) Windows 10 10.0

Next maybe you should try below :

If everything is working as expected, the next step is to trigger a few HTTP requests on your application/tomcat server, then wait for the data to be sent to the APM backend. If there are any communication issues this should be visible in the standard output as well.

Thanks!!

Hi @Tortoise

It is working when i am running tomcat by using startup.bat and catalina.bat , however if i run tomcat as tomcat9 service then it is not working. The service file is not taking up the environment variable. I have pasted the logs below for your reference.

Hello @Aniket_Pant

From the below post i believe the location of setenv.bat can be causing issue ?

In your case we see below :

As per the logs shared it should be available in path C:\apache-tomcat-9\bin :

22-Nov-2025 18:55:22.288 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log CATALINA_BASE:         C:\apache-tomcat-9
22-Nov-2025 18:55:22.288 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log CATALINA_HOME:         C:\apache-tomcat-9

Thanks!!

Sorry i mentioned wrong path.

setenv.bat is present only in C:\apache-tomcat-9\bin

When running as a Windows service, it is likely that the environment variables set through the usual `setenv.bat` are ignored, you should use the `tomcat9w` executable to edit the service configuration: Apache Tomcat 9 (9.0.112) - Windows Service How-To

@Sylvain_Juge yesterday i research on this that when tomcat is running as service on windows(don’t know about linux) it won’t read setenv.bat file , we have to configure in tomcat9w.exe . I did it.
I think elastic has to document below advise also .

I am sorry i am asking another question . Whatever i did is testing one java app (running on tomcat) on my system. I want to test in client system , so i have javaagent parameter , restart the tomcat service and on kibana service inventory i was able to see the service name but not getting transactions data .

16

In this case this is probably because the client application is not using one for the supported technologies.

In this case, you should try with the EDOT Java agent instead, as it has broader support.

17

Hi @Sylvain_Juge ,

How can we get to know the client app is using this java technology not this. The application team told me that they are using java and tomcat.

18

Now in tomcat9w.ext i have otel parameters.

-Dotel.exporter.otlp.endpoint=https://50657be900ce43f2bd5c58af83ae4733.centralindia.azure.elastic-cloud.com:443
-Dotel.resource.attributes=service.name=Login_UI,deployment.environment=Development
-Dotel.exporter.otlp.headers=Authorization=Bearer <token>
-Dotel.metric.exporter=otlp
-Dotel.logs.exporter=otlp

But in transactions i am getting weird APIs.POST /* , GET /**

These are fallback names when the instrumentation can’t find a more useful name. Your application is now instrumented and producing transactions. One thing you should do is remove or redact your otel.exporter.otlp.headers line above, as this is a public forum

I was using elastic cloud free trail. It is expired already.

As i mentioned earlier, in kibana > observability> Services. I am able to see app service name and infra metrics(cpu,memory,heap etc).

I have restarted the app and in tomcatstdout . I found below warnings.

This app is COTS product and this app is used for scheduling the jobs.

I wanted to know if i set `elastic.apm.instrument_ancient_bytecode=true` , will this work ? or it impact app performance ?
