Useful RedHat commands for administering apache/mysql webserver?

[Ragnarak]

I'm looking for any useful commands for monitoriing the performance of a webserver.

/etc/init.d/httpd restart

/etc/init.d/mysqld restart

mysqladmin -u root -p variables

/etc/init.d/mysqld status

mysqladmin -u root -p status

view active connections
netstat -an | grep :80 | grep EST

number of active connections
netstat -an | grep :80 | grep EST | wc -l

The above are all the ones i've found at the minute.

I'd also be interested in a command that shows how the hardware is handling. How much ram is free, how much ram there is in total, what the cpu speed is, etc.

Thanks for any help guys.
