Description of problem: the rpm installed agent uses "service jon-agent start" command to startup. but there is no procedure to configure the agent, it cannot connect to the server. Version-Release number of selected component (if applicable): 3.1.0-el6 How reproducible: 100% Steps to Reproduce: 1. freshly install the agent through rpm installation 2. start the agent by "service jon-agent start" command 3. wait, and look at the server side. Actual results: no procedure to configure the agent to connect to a specific server, the agent cannot connect to the server. Expected results: A prompt should be shown to configure the agent for the first time running. After configuring the server's ip address and other parameters, the agent should be able to connect to the server. Additional info:
discussed with stefan_n and zjin. this is a solid BZ. the mechanism for the agent to connect with the appropriate JON server is config file updates. the question is how to do this through the RPM process. possibilities: 1) documentation? 2) manual config file updates after the RPM install? assigning to stefan. this will require conversations with crouch, asantos, and loleary to define requirements here ... and determine what approach is best or acceptable for customers.
The agent can be configured post RPM installation with the help of the configuration file ({agent-folder}/conf/agent-configuration.xml). There are several settings that can be updated to point to the correct server and port. The process would be: 1) Install RPM 2) Update the configuration file 3) Restart the agent service However, this might not desirable for cases where users try to provision multiple machines with automated installation scripts. Will need to further identify user needs and usage patterns to derive requirements and a solution.
documentation. and the jon agent rpm demo by alexksandar bridges the gap on this. bz triage by asantos, mfoley, zjin, armine, loleary, viet.
service rhqagent config ..... <<<<---this is a development activity that could be added ... stefan ... could you add this? bz triage by loleary, asantos, armine, zjin, foley, viet
There are two ways to improve the user experience with regards to agent configuration: 1) Update the documentation to clarify all the possible ways available to configure the agent (config files, environment variables, service options) 2) Add an option to the service script to allow the user to configure the agent. To get the typical interactive prompt for the rhq-agent the user would use the command "service jon-agent config" which in turn would call "rhq-agent.sh --setup --nostart"
Suggestion 2 cannot be implemented without changes to the agent and the wrapper script. So this suggestion would require changes to JON and a full build of JON in brew. I recommend adding this functionality as part of JON 3.1.1. Suggestion 1 should be sufficient because it is related to functionality delivered with the regular agent today. Suggestion 2 is just an improvement over the functionality currently delivered with regular agent installations.
This bz is for implementing option 2 as part of jon311
@Stefan, could you please put this bug as ON_QA so that we could mark it as verified (for case 2 as Charles described). Actually it's verified already. service jon-agent config works and makes correct configuration, which leads to correct agent/server cooperation.
JON 3.1.1 ER1 build is available. Moving to ON_QA. https://brewweb.devel.redhat.com/buildinfo?buildID=226942
Moving back to ON_DEV. This should not have been moved to ON_QA as incorrectly noted in comment 9.
verified since comment #8.
