Christian Haudum, aka 'Haudi', is one of Crate.io's integration engineers. During the recent Snow Sprint, amongst other things, Haudi decided to create ctop, a process monitoring tool for Crate.
Getting ctop
ctop is built in Python, so clone the repository and use buildout to get the tool onto your system and ready for use.
git clone https://github.com/chaudum/crate-top.git
cd crate-top
python3.4 bootstrap.py
bin/buildout -N
Using ctop
bin/ctop --hosts SERVER_IP:4200
Where SERVER_IP is a comma separated list of Crate instances you wish to connect to, with the Crate transport port appended.
Haudi hopes to add more functionality to the project over the coming months, so keep an eye on it's GitHub repo if you like what you see.
