DataStax’s OpsCenter is pretty, but sometimes you don’t want to chop holes in your firewall for the server and agents.
So I wrote cass_top. It works like top, but colorizes the output of nodetool status. It also lets you build nodetool commands using menus, run and log the output.
What’s especially nice is that it uses bash (no python required), and uses minimal screen real estate, so you can view all your clusters on one monitor using eterms.
$ cass_top 10.0.1.140
