The command I typically use is top.  There is also htop, which is a more modern take on the features of top.

Other commands that can be useful include:

• vmstat
• free
• ps
• lsof

 

If you want monitoring, which typically means, graphing time series for performance issues, then there are a wide variety of options and ever changing landscape.  

Popular options like Nagios, Zabbix, Monit and Munin all have options for performance monitoring and graphing, and there are new tools popping up all the time, like monitorx and Graphite.
