Adding Java Agent Arguments in Message Processor StartUp

Google Cloud Apigee

Hi All,

We would like to add a third party monitoring agent in our message processor (Elastic APM). We are trying to add the below arguments as part of the jvm startup.

  • -javaagent:/tmp/agent/elastic-apm-agent-1.3.0.jar
  • -Delastic.apm.service_name=apigee
  • -Delastic.apm.application_packages=com.package
  • -Delastic.apm.server_urls=http://[host-ip]:8200

We are getting below behavior when we added/updated the arguments in the following:

  1. When doing the apigee messageprocessor startup/restart, we are expecting the value to be like below when the server started but, we notice that setenv.sh ext_jvm_opts returns to “” which was its initial value before the update.

/opt/apigee/edge-message-processor-4.18.05-0.0.1580/bin/setenv.sh

Expected:

ext_jvm_opts=“$ext_jvm_opts -javaagent:/tmp/agent/elastic-apm-agent-1.3.0.jar -Delastic.apm.service_name=apigee -Delastic.apm.application_packages=com.package -Delastic.apm.server_urls=http://[host-ip]:8200”

Actual Value after restart:

ext_jvm_opts=

  1. apigee message processor won’t start and going to dead status.

/opt/apigee/edge-message-processor-4.18.05-0.0.1580/bin/start

custom_jvm_opts=“-javaagent:/tmp/agent/elastic-apm-agent-1.3.0.jar -Delastic.apm.service_name=apigee -Delastic.apm.application_packages=com.package -Delastic.apm.server_urls=http://[host-ip]:8200”

Launching java

exec $JAVA -classpath “$classpath” -Xms$min_mem -Xmx$max_mem $xx_opts -Djava.security.auth.login.config=$conf_path/jaas.config -Dinstallation.dir=$install_dir $sys_props -Dconf.dir=$conf_path -Ddata.dir=$data_dir $custom_jvm_opts $ext_jvm_opts $* $debug_options com.apigee.kernel.MicroKernel

Note: We deliberately use [host-ip] to substitute/hide the real host-ip we are using for this post.

The issue for running the agent is solved. The folder and file location was not owned by apigee which causes MPR not to startup.
