Java agent in IBM Websphere 8.5.5 not send events

fernandezsjanto · May 11, 2021, 11:50am

Kibana version:
7.10.1
Elasticsearch version:
7.10.1
APM Server version:
7.10.2
APM Agent language and version:
java 1.23.0
Browser version:

Original install method (e.g. download page, yum, deb, from source, etc.) and version:
download page
Fresh install or upgraded from other version?
Fresh install
Is there anything special in your setup? For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc.

Description of the problem including expected versus actual behavior. Please include screenshots (if relevant):
The agent is installed on an instance of websphere 8.5.5.19, running on an IBM java 1.8_64 virtual machine.

The agent configuration is as follows:
'''
-javaagent: L: \ path \ elastic-apm-agent.jar
-Delastic.apm.service_name = 18corporatives
-Delastic.apm.environment = DEVELOPMENT
-Delastic.apm.server_url = http: // url: 8200
-Delastic.apm. log_file = L: /path/elastic-apm-agent_18corporativas.log -Delastic.apm.application_packages = es.iam
'''
The agent does not send the instrumentation events to the server, the VM metrics if they arrive correctly.

The following entries appear in the agent log:
'''
WARN co.elastic.apm.agent.bci.bytebuddy.ErrorLoggingListener - org.apache.commons.discovery.jdk.PsuedoSystemClassLoader uses an unsupported class file version (pre Java 4}) and can't be instrumented. Consider updating to a newer version of that library.

Hi @fernandezsjanto ,

Can you provide the first lines of the agent log ?

Those lines should contain the non-default parameter values used by the agent, that allows to check for any difference (for example parsing error) with the values that you have set through configuration. Also, configuration could be set at multiple levels and overriden (see doc
)

Regarding those warning messages, they are related to trying to instrument very old java bytecode. Given that only slf4j seems impacted there should be no consequence here, unless you try to use log correlation, in which case the feature might not work (agent has to instrument logger library in order to inject current transaction/span ID into logs).
Upgrading to a newer version of slf4j library is the most straightforward way to deal with this for now.

What happens later?
Do you see any interesting Method match for instrumentation ... messages as well?
What happens even later when you invoke requests on your WAS? Anything gets logged then?

Hi @fernandezsjanto ,

From the logs samples that you sent, we don't see what could be wrong here

If I understand correctly:

you added the Java agent version 1.23.0 using the -javaagent JVM option
the application server starts, and the application works as expected
you get some metrics visible in Kibana, but nothing else

In order to double-check, could you do the following

truncate both agent log and Websphere logs for easier debugging
keep the log_level=debug configuration
Execute a few requests against the server, the agent should capture those as transactions, for example open the WAS admin console.
inspect the logs for any error, when log_level=debug is set, you should see some captured URLs in lines that contain endTransaction

Thanks !

Side note, there appear to be a docker image for that Websphere version if required : Docker Hub

Hi,
I have emptied the logs and activated the 'TRACE' level, in the agent.
The result is the same, I add some new traces:

The string "EndTransaction" does not appear in the log.

PS: I am using the websphere Network Deployment

Sylvain_Juge · May 19, 2021, 11:57am

@fernandezsjanto can you upload the whole log ? The string to search in log is endTransaction with a lowecase 'e' at begining.

I'm really not familiar with Websphere Network Deployment, what is the difference compared to a regular standalone setup ? Is there any kind of internal load-balancing/clustering setup ?

Elastic APM agent is only able to monitor supported frameworks, for example anything that relies on Servlets should be supported, do you know which frameworks are being used by your application to deal with HTTP requests & responses ?

Can you make HTTP requests to the specific node where you added the -javaagent option, or does it has to use the load-balancing/cluster feature ?
