Alternative to diagnostic_aggregator and robot_monitor?

edit

Firstly, my first post, hello everyone!

I have been working with /diagnostics topic recently. Mostly for urg_node and mavros. I was wondering if there is any reasonable, maintained alternative to diagnostic_aggregator and robot_monitor? Basically I need a very simile GUI or terminal app that will consume /diagnostics topic, check names/keys/values against provided template and display overall status information. I know about rqt_runtime_monitor but it doesn't quite do what I need, it just displays whatever comes in.

Thanks Marcin
