APM Java Agent - manual setup

Jurilz · December 14, 2020, 1:55pm

Kibana version : 7.10.0

Elasticsearch version : 7.10.0

APM Server version : 7.10.1

APM Agent language and version : Java - elastic-apm-agent-1.19.0.jar

Browser version : Firefox 83.0

Original install method (e.g. download page, yum, deb, from source, etc.) and version :

docker for elasticsearch, kibana, logstash and apm-server
apt-get for tomcat9

Good day,

I'm trying to monitore an apache tomcat9, which I set up locally under Ubuntu and can successfully reach under http://localhost:8080

So I naturally followed these instructions: https://www.elastic.co/guide/en/apm/agent/java/current/setup-javaagent.html

for the manuel setup with -javaagent flag.

I downloaded the elastic-apm-agent-1.19.0.jar from maven central.

Then I created bin/setenv.sh with the content:

export CATALINA_OPTS="$CATALINA_OPTS -javaagent:<path-to-my-elastic-apm-agent>.jar"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.service_name=my-cool-service"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.application_packages=org.example,org.another.example"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.server_urls=http://localhost:8200"

Afterwards I made the setenv.sh executable with

chmod +x bin/setenv.sh

I executed the setenv.sh with sh setenv.sh and restarted the tomcat server with

sudo service tomcat9 restart

But Kibana still tells me that: No data has been received from agents yet. The apm-server is reachable under http://apm-server:8200.

apm-server. yml:

apm-server:
  host: "0.0.0.0:8200"

output.elasticsearch:
  hosts: ["https://es01:9200"]
  username: "elastic"
  password: <my_pw>
  ssl.certificate_authorities: ["/usr/share/elasticsearch/config/certificates/ca/ca.crt"]

The apm-server logs:

I not sure where my error lies, therefore I looking forward to any help.

Hi and thanks for your questions.

Could you please upload the debug logs of the agent? See also https://www.elastic.co/guide/en/apm/agent/java/current/trouble-shooting.html for more details. By default, the logs should be in catalina.out but you can customize the location by setting log_file.

Thanks for your support. The catalina.out logs are:

I tried to change the log_level in the setenv.sh to:

export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.log_level=DEBUG"

But I'm not sure if it's working.

Sylvain_Juge · December 14, 2020, 3:57pm

I'm not sure about it, but where did you created the setenv.sh file ? Is it in $CATALINA_BASE/bin/setenv.sh or $CATALINA_HOME/bin/setenv.sh

org.apache.catalina.startup.VersionLoggerListener.log CATALINA_BASE:         /var/lib/tomcat9
org.apache.catalina.startup.VersionLoggerListener.log CATALINA_HOME:         /usr/share/tomcat9

Jurilz · December 14, 2020, 4:29pm

I feel a littlbe bit stupid, because I created the setenv.sh in /bin not in /usr/share/tomcat9/bin.

After I corrected this mistake and set up the kibana host, there seems to be a successfull start of the apm-agent and a connection to the apm-server.

Unfortunately Kibana tells me that the Agent Status is: No data has been received from agents yet

Jurilz · December 15, 2020, 11:41am

My current

amp-server.yml:

apm-server:
  host: "0.0.0.0:8200"

  kibana:
    host: "https://kib01:5601"
    username: "elastic"
    password: <my-pw>
    ssl.enabled: true
    ssl.certificate_authorities: ["/usr/share/elasticsearch/config/certificates/ca/ca.crt"]

output.elasticsearch:
  hosts: ["https://es01:9200"]
  username: "elastic"
  password: <my-pw>
  ssl.certificate_authorities: ["/usr/share/elasticsearch/config/certificates/ca/ca.crt"]

And the current /usr/share/tomcat9/bin/setenv.sh:

export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/<path-to-my>/elastic-apm-agent-1.19.0.jar"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.service_name=my-cool-service"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.application_packages=org.example,org.another.example"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.server_urls=http://localhost:8200"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.log_level=DEBUG"

Although according to Kibana the agent status is "No data has been received from agents yet", I can load Kibana objects and launch an APM Dashboard in Kibana, with some information about requests per minute. I don't know how much it matters that my tomcat9 is currently "blank", i.e. that nothing happened to it after the install.

Hi @Jurilz,

Have you checked the apm-* indices in Kibana/Elasticsearch ?
When the app is running (but without any transactions), metrics are collected (about every minute by default if I remember correctly).

From the last line of server logs, we can see that the agent seem able to connect:

INFO	[request]	middleware/log_middleware.go:101	request accepted	{"request_id": "55d83265-22ad-4a15-95e0-fa654a81e161", "method": "POST", "URL": "/intake/v2/events", "content_length": -1, "remote_address": "172.22.0.1", "user-agent": "elasticapm-java/1.19.0", "event.duration": 10019554918, "response_code": 202}

Jurilz · December 17, 2020, 9:59am

The apm-* indices, especially the apm-7.10.1-metric-000001 look just fine.

I'm irritated by Kibana's saying that agent status is "No data has been received from agents yet".

Apart from that everything seems to work fine so far. Of course I will know more about the status, when I'm using the apm agent on a tomcat server, that is really used.

Sylvain_Juge · December 18, 2020, 3:42pm

I don't know about the heuristic that is used to detect if any data has been captured here, did this message still appears once you have executed a few transactions ?

If you started your application metrics will be collected even if there is no traffic on the app, unlike transactions and spans which are only captured passively when there is some requests made to the server (in your case tomcat).

Jurilz · December 21, 2020, 4:47pm

I just checked and this message appears even after a lot of transcation.

Apart from the message the APm agent and server seem to work fine.
