Using OSGI to display information about the Liberty configurations. Useful commands

This post gives some of the commands you can issue to OSGI in Liberty.

I set up access to Liberty OSGi using

<featureManager>
 <feature>osgiConsole-1.0</feature> 
</featureManager>

osgi.console=10.1.3.10:5471. in bootstrap.properties file, and restarted Liberty.

Once it was active I used

telnet 10.1.3.10 5471 |tee -i osgi.log

to issue commands to OSGI and save the output in the osgi.log file.

A subset of the display commands
