I'm looking for tools to monitor the linux system. I would like to know what are the best/ most used monitoring tools for linux, preferably command-line or with the possibility to be used from the command line too.
I am aware that are a lot of individual tools for monitoring a specific resource, but I want to know if there is a "all in one" system monitoring tool that can be used.
It will depend on what you pretend to do with it, if is just want to read some info from your system from time to time, there are lots of commands like top (cpu process usage), ps -le (process status), lm-sensors give you a bit more info. Then you have other ones that give you info constantly on your desktop like gkrellm or conky. googling you will find a lot more options..
To monitor your Linux system's performance locally I would suggest you to read http://www.tecmint.com/command-line-tools-to-monitor-linux-performance/ and http://www.cyberciti.biz/tips/top-linux-monitoring-tools.html
