I was recently introduced to htop – it generates a really nice UI to. see what’s going on.
- Install htop
yum install htop -y ... Transaction test succeeded Running transaction Installing : htop-2.2.0-3.el7.x86_64 1/1 Verifying : htop-2.2.0-3.el7.x86_64 1/1 Installed: htop.x86_64 0:2.2.0-3.el7 Complete!
2 – Type htop, and start diagnosing (iostats also helps)
