Error in APM agent during startup

Elastic Observability APM
1

Kibana version: 7.6.2

Elasticsearch version: 7.6.2

APM Server version: 7.6.2

APM Agent language and version: Java 1.12.0

Browser version:

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

Fresh install or upgraded from other version?

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.

NO

Description of the problem including expected versus actual behavior. Please include screenshots (if relevant):

I have a java APM agent attached to a springBoot application. I can see the application listed in APM server but none of the transactions are getting reflected in APM dashboard. This is the issue I'm facing.

I could see the JVM related information in APM dashboard. But the problem is transactions are not getting reflected, even after I send multiple transaction in my application.

Below are the log, in which you can see one error and thereafter same set of statements are repeatedly printed.

Hi @jibitgeorge,

The 1.12.0 version is a bit old, could you try to update to the latest version 1.17.0 to see if there is still an issue ?

Also, which version of Spring boot are you using ? Does the application is servlet-based or relies on another framework like Webflux (not yet supported) ?

For the exception we can see in the partial logs you provided, it should be possible to disable spring-service-name instrumentation by setting disable_instrumentations=spring-service-name, and that would also require to set service_name explicitly as it won't be detected automatically from Spring configuration.

@Sylvain_Juge Thanks for the reply

I will try by upgrading the agent version.

To answer your question, I'm using Sprint Boot 2.0.1
