I want to create a custom dashboard web app thing for the purpose of learning and to make it avalaible for selfhosted servers.

The plan is to use existing linux cli tools as much as possible… Which of them do you think are appropriate for that purpose?

There is a nice list in this blogpost but I dont have any experience with any of them: https://www.brendangregg.com/blog/2024-03-24/linux-crisis-tools.html
