I am trying to use APM, configured APM server and Java agent in the same machine as shown in the documentation. apm-server.yml apm-server: host: "localhost:8200" output.elasticsearch: hosts: ["server-1:9200"] indices: - index: "apm-%{[beat.version]}-sourcemap" when.contains: processor.event: "sourcemap" - index: "apm-%{[beat.version]}-error-%{+yyyy.MM.dd}" when.contains: processor.event: "error" - index: "apm-%{[beat.version]}-transaction-%{+yyyy.MM.dd}" when.contains: processor.event: "transaction" - index: "apm-%{[beat.version]}-span-%{+yyyy.MM.dd}" when.contains: processor.event: "span" - index: "apm-%{[beat.version]}-metric-%{+yyyy.MM.dd}" when.contains: processor.event: "metric" - index: "apm-%{[beat.version]}-onboarding-%{+yyyy.MM.dd}" when.contains: processor.event: "onboarding" I have installed Java agent in the same machine and created a sample helloworld project using servlets and tomacat. setenv.sh export CATALINA\_OPTS="$CATALINA\_OPTS -javaagent:/root/elastic-apm-agent-1.1.0.jar" export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.service\_name=my-service" export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.application\_packages=org.example" export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.server\_urls=http://localhost:8200" export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.active=true" export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.capture\_body=all" export CATALINA\_OPTS="$CATALINA\_OPTS -Delastic.apm.log\_level=DEBUG" When I start the tomcat server I can see a log entry in APM server as following 2018-11-29T10:09:35.913-0500 INFO template/load.go:82 Loading template for Elasticsearch version: 6.4.1 2018-11-29T10:09:36.159-0500 INFO template/load.go:145 Elasticsearch template with name 'apm-6.5.1' loaded 2018-11-29T10:09:36.159-0500 INFO pipeline/output.go:105 Connection to backoff(elasticsearch([http://server-1:9200](http://server-1:9200))) established 2018-11-29T10:18:31.520-0500 INFO [request] beater/common\_handlers.go:272 handled request {"request\_id": "ba321c65-9b2c-4f85-b944-45cda49de6c3", "method": "GET", "URL": "/", "content\_length": 0, "remote\_address": "127.0.0.1", "user-agent": "Java/1.8.0\_191", "response\_code": 200} 2018-11-29T10:32:57.186-0500 INFO [request] beater/common\_handlers.go:272 handled request {"request\_id": "6ec62ab7-5d17-40a4-ab13-ead9c6ef5300", "method": "GET", "URL": "/", "content\_length": 0, "remote\_address": "127.0.0.1", "user-agent": "Java/1.8.0\_191", "response\_code": 200} 2018-11-29T15:02:48.719-0500 INFO [request] But why can't I see the service name in APM UI and dashboards ![image](https://us1.discourse-cdn.com/elastic/original/3X/a/e/ae964c3053f8ffd9d09d0af1622cbb20f11501be.png) ![image](https://us1.discourse-cdn.com/elastic/original/3X/4/4/441474c99d89fd09dac51f7120c13405bba14fbd.png) ---

Hi, Thanks for trying out Elastic APM! > [@shiv94](#): > > {"request\_id": "6ec62ab7-5d17-40a4-ab13-ead9c6ef5300", "method": "GET", "URL": "/", "content\_length": 0, "remote\_address": "127.0.0.1", "user-agent": "Java/1.8.0\_191", "response\_code": 200} That is only a log for the healthcheck and it seems like no actual data has made it to the server, that would go to the URL `/v2/events`. > [@shiv94](#): > > I have installed Java agent in the same machine and created a sample helloworld project using servlets and tomacat. The agent currently only supports `HttpServlet`s, this is something to be aware of. If you have used `HttpServlet`s and it's still not working, please enable debug logging for the agent and upload the whole agent log here. Cheers, Felix ---

Thanks for the response. I have used HttpServlets, there was a problem with tomcat server. your information helped me to find a solution. Thanks 🙂 ---

If you could take the time, it would be great if you could describe your solution as it might help others with similar problems 🙂 ---

yeah sure. Tomcat server was running already and I tried to start the tomcat server again it showed me the output as Using CATALINA\_BASE: /opt/apache-tomcat-8.5.35 Using CATALINA\_HOME: /opt/apache-tomcat-8.5.35 Using CATALINA\_TMPDIR: /opt/apache-tomcat-8.5.35/temp Using JRE\_HOME: /usr Using CLASSPATH: /opt/apache-tomcat-8.5.35/bin/bootstrap.jar:/opt/apache-tomcat-8.5.35/bin/tomcat-juli.jar Tomcat started. But, in the logs I found Caused by: org.apache.catalina.LifecycleException: Protocol handler initialization failed at org.apache.catalina.connector.Connector.initInternal(Connector.java:995) at org.apache.catalina.util.LifecycleBase.init(LifecycleBase.java:107) ... 12 more Caused by: java.net.BindException: Address already in use I killed the existing process and started the tomcat server again then in the logs I can see the transactions. ---
