Can I control the hostname of agents inside a docker container?

[Chris Milazzo]

I dont want to see a random hostname each time.  

 

 

 

#caheadband

Hi Chris,

This is Guenter's example of how to configure it

GitHub - CA-APM/ca-apm-example-docker-tomcat: This example shows how to install a CA APM Java agent in a Tomcat Docker c… 

 

It mentions being able to control the agent hostname through an environment variable

Optional: set the environment variable AGENT_HOSTNAME to a persistent hostname (e.g. the container name) that will be used instead of the container id for identifying the CA APM agent.

 

I'm not sure of anything more clever yet, like being able to actually derive the host it is really running on.

 

Thanks,

David

Thanks.

 

i think I did set ENV HOSTNAME which is docker variable..   Ill try AGENT_HOSTNAME next thanks.

[Chris Milazzo]

ENV AGENT_HOSTNAME="flintstone."
ENV HOSTNAME="flinststone"

Did you consult with your Docker captain?

Hi,

We set the following attribute in our agent profile:-

 

introscope.agent.hostName=OSEV3-PROD

 

Thanks,

thank you Andrew 

 

added the following to init_agent.sh which was from Guenters example

 

sed -i -e "\$aintroscope.agent.hostName=caheadband" $WILY_HOME/core/config/IntroscopeAgent.profile
