Do I need to do anything else to install plugins in redmine 2 or write routes any other place. One more thing both the plugin is written in rails 2 so I change the routes file to rails 3 routes file.

Answer 1

Redmine Monitoring Controlling Plugin is ready to Redmine 2.0.

Check last commit on git repository: https://github.com/alexmonteiro/Redmine-Monitoring-Controlling

Answer 2

Plugins based on Redmine 1.x will break on 2.0

See the redmine2.0 release news --> http://www.redmine.org/news/66

The monitoring_controlling plugin is not Redmine2.0 compatible yet(unlilke advertised) and I have opened up an issue here --> https://github.com/alexmonteiro/Redmine-Monitoring-Controlling/issues/17#issuecomment-5806223

You need to change the Route files(one of the changes). More for understanding the general scope of writing future proof plugin, this discussion might be of some use -->
