[CentOS] System and Server Status help ?

dear all,

i can't count the times that webmin came to my rescue.
whenever i face a dead end in doing something through CLI i always turn to webmin..
though at the moment i wanna learn how to do things through cli instead of relying on webmin as i said..
especially "System and Server Status"
theres a module that supports such a thing where i can set monitors that checks specific services or directories or... and reports the output..
so i wanna do this through command line.. any help ? 
i've checked crontab -l and it doesnt list anything that i've set in webmin
so where is it and how to do it through cli ?
