Help with configuring APM elastic agent

Elastic Observability APM
1

hello,

I'm setting up APM for my single node ELK stack and unfamiliar with JAVA parameters . The apm-server has been set up correctly .

The instructions to set up were being followed from Kibana's APM tutorial . what am i doing wrong. ?

root@dev-elk-app01:~#  java -javaagent:/home/sn/elastic-apm-agent-1.26.0.jar      -Delastic.apm.service_name=apm-server      -Delastic.apm.server_urls=http://172.26.207.164:8200      -Delastic.apm.secret_token=      -Delastic.apm.application_packages=org.example      -jar apm-server.jar
Error: Unable to access jarfile apm-server.jar

APM version: 7.15
Kibana/Elasticsearch/Logstash version : 7.15

Have you tried putting both the java agent and jar file in the same directory oy using absolute paths ? Also file permissions?

These are the permissions

root@dev-elk-app01:/home/sn# ls -l elastic-apm-agent-1.26.0.jar 
-rwxr-xr-- 1 sn users 9320601 Sep 23 07:45 elastic-apm-agent-1.26.0.jar
root@dev-elk-app01:/home/sn#

Also what did you mean by placing both java agent and jar file in the same directory ? i thought javaagent was an argument to java

Following the opbeans example, this worked for me. The problem with yours looks like accessing what comes after

-jar

Seems to be where the issue is

java -javaagent:elastic-apm-agent-1.26.0.jar -Delastic.apm.service_name=opbeans-java -Delastic.apm.server_urls=https://my-apm.server.com -
Delastic.apm.environment=Development -Delastic.apm.application_packages=co.elastic.apm.opbeans -jar /home/pi/opbeans-java/opbeans/target/opbeans-0.0.1-SNAPSHOT.jar```

okay , that seemed to have worked

any suggestions on how i could fix this

Shouldn't you be pointing to your application and not the apm agent?

-jar apm-server.jar

i did try it , had the same error after specifying the absolute path .

root@dev-elk-app01:~# java -javaagent:/home/sn/elastic-apm-agent-1.26.0.jar -Delastic.apm.service_name=apm-server      -Delastic.apm.server_urls=http://172.26.207.164:8200      -Delastic.apm.secret_token=      -Delastic.apm.application_packages=org.example      -jar /home/sn/apm-server.jar
Error: Unable to access jarfile /home/sn/apm-server.jar

Your syntax is connect and you did get previously a response to saying you Elastic APM server was up and running. Could it be the application itself? Maybe try running a control test by following the opbeans tutorial ?
