If you are looking to help Hawkular and want to make a difference in monitoring solutions, here are a few ideas, contact us (in comment, message, twitter, hawkular-dev mailing list...) if you are interested. Anything below are just ideas, feel free to propose anything related or unrelated to this list

Mobile application

Being able to see how the servers are behaving from a phone or tablet is becoming the norm, not everyone sits in front of a computer all day.

Mobile push notifications

Related to the previous subject but could be a first step, integrating with Aerogear UPS would allow a user to receive alert notifications pushed to his phone.

Research work has been done in the past for the RHQ project: http://pilhuhn.blogspot.ch/2014/04/aerogear-ups-alert-plugin-for-rhq.html
