No JVMs were found APM

User28 · November 4, 2022, 10:16am

Hi,
Elasticsearch - v7.17.4
Kibana - v7.17.4
APM Server - v7.17.4
Opentelemetry agent - v1.11.0

In Kibana APM JVM UI, it says No JVMs were found

service.node.name is also set

We have sending observability data from Opentelemetry collector to Elastic APM. We see all timelines, latency, logs, errors but not not JVM metrics

User28 · November 6, 2022, 5:18pm

Is this the limitation?

stephenb · November 6, 2022, 5:34pm

Perhaps this?

And / Or are you adding the correct modules to collect the JVM Metrics?

opentelemetry-java-contrib: Provides helpful libraries and standalone OpenTelemetry-based utilities that don’t fit the express scope of the OpenTelemetry Java or Java Instrumentation projects. For example, JMX metric gathering.

I am running 8.4.3 and do not see JVM but I have not added the contrib JMX so I am a little confused as well... I will try 8.5.0 and see what I see.... Nope I do not see in 8.5.0 as well...

Perhaps @alexander.wert can help both of us

Do we need something besides just the base Java OTEL Agent? here

Do we need to run the jmx contrib as a separate process?

Just for reference my start up looks like this .. I see traces transaction call to DB but no JVMs

export OTEL_RESOURCE_ATTRIBUTES=service.name=cardatabase-local-otel,service.version=1.1,deployment.environment=production
export OTEL_EXPORTER_OTLP_ENDPOINT=https://adsasfdsafd.apm.us-west2.gcp.elastic-cloud.com
export OTEL_EXPORTER_OTLP_HEADERS="Authorization=Bearer asdfasdfasdfasdfasdf"
export OTEL_METRICS_EXPORTER="otlp"
export OTEL_LOGS_EXPORTER="otlp"
java -javaagent:./opentelemetry-javaagent.jar \
     -jar target/cardatabase-0.0.1-SNAPSHOT.jar

I tried using the contrib, still confused whether I need this or not the Missing JVM Github issue above seems to lead me to think not.. but without contrib I get nothing.

Note this is on Elastic Stack 8.5.0

Now App Startup

export OTEL_RESOURCE_ATTRIBUTES=service.name=cardatabase-local-otel,service.version=1.1,deployment.environment=production
export OTEL_EXPORTER_OTLP_ENDPOINT=https://test.apm.us-west2.gcp.elastic-cloud.com
export OTEL_EXPORTER_OTLP_HEADERS="Authorization=Bearer fb6mQwEYrKe3KC4tiO"
export OTEL_METRICS_EXPORTER="otlp"
export OTEL_LOGS_EXPORTER="otlp"
java -javaagent:./opentelemetry-javaagent.jar \
    -Dcom.sun.management.jmxremote \
    -Dcom.sun.management.jmxremote.port=9010 \
    -Dcom.sun.management.jmxremote.local.only=false \
    -Dcom.sun.management.jmxremote.authenticate=false \
    -Dcom.sun.management.jmxremote.ssl=false \
    -Djava.rmi.server.hostname=localhost \
    -jar target/cardatabase-0.0.1-SNAPSHOT.jar

With contrib...

session.properties

otel.jmx.service.url = service:jmx:rmi:///jndi/rmi://localhost:9010/jmxrmi
otel.jmx.target.system = jvm
otel.jmx.interval.milliseconds = 5000
otel.metrics.exporter = otlp
otel.exporter.otlp.endpoint = https://sdgfsddsfg.apm.us-west2.gcp.elastic-cloud.com
otel.exporter.otlp.headers = "Authorization=Bearer sfgsdfgsdfg"

Run it .. get a few errors... then looks like it is shipping

But then in the Kibana UI

But it is shipping something

@User28

@alexander.wert Feel Free to correct me...

Turns out my Config Does Work.

Note I did use 8.5 so I have 7.17.4

To Gather JVM Metrics with OTEL you need to use the contrib package and collect via JMX.
Secondly you will need to build a couple visualizations as OTEL / JVM / JMX does not deliver the metrics in a compatible form with our Curated UI for JVM Metrics.

I did in fact validate I am gathering metrics and the metrics in the APM data View ...
So in the mean time you would need to build some visualizations on your own.
Stay Tuned.

Yup I can pretty much build the Viz... Here is the Heap

User28 · November 7, 2022, 5:08pm

@stephenb Thank you for sharing info

I managed to get memory metrics by just adding OTEL_METRICS_EXPORTER:otlp in the environment of the application

Note: I 'm using OTel collector as side car to monitor the application.

But somehow i don't see CPU usage and System memory usage

Otel Collector yaml :

apiVersion: opentelemetry.io/v1alpha1
kind: OpenTelemetryCollector

Hi @User28

2 Things

1st I am not an expert on sidecars etc but it looks to me you are not using the the JMX metrics gatherer, my understanding today that is the only way to get JVM metrics see here

2nd Even after you get that working Today, the JVM metrics that OTEL creates are not directly compatible with the fields in the Elastic APM App so you would need to build your own dashboards... Our APM Team is thinking about Compatibility for metrics but for the short term they are not. (I think you are getting the Heap / Non Heap Memory "By Coincidence")

Perhaps I could help with some viz dashboard at some point after you get the data

After you get the data in... you should be able to see it in Discover I suspect if you went to discover you would not see that data...

So get that data in... then we will take a look at Viz... If you have it already great!

User28 · November 9, 2022, 6:28pm

Hi @stephenb ,
I still didn't got JVM data.

Can you please share how you have used contrib to make it work. Did not find any example:

Thanks

stephenb · November 9, 2022, 9:02pm

Where are you looking for the Data? In Discover?

Also you are doing this in K8s I think I have no clue how to set JMX in K8s.

Here is my simple example btw I am bvader on github

git clone https://github.com/bvader/cardatabase.git

cd cardatabase

curl -O  https://repo1.maven.org/maven2/co/elastic/apm/elastic-apm-agent/${AGENT_VERSION}/elastic-apm-agent-1.34.0.jar

This seems pretty experimental at this point in my opinion.

if you run this several time it will create some transactions...

$ curl localhost:8080/api/cars

Then you should be able to see data as I showed Above this is with Elastic Stack 8.5
