With open source packages like
nagios
and
cacti
monitoring your systems, an administrator can have graphs and up to the
minute
reports of CPU usage, memory usage, disk usage, load average, and any
other system variable. We can also integrate these programs with your
applications to provide accounting and reporting for any variable
(users connected, page views, etc.).
We deploy open-source log processing utilities like
webalizer
to generate continually updated charts and graphs from webserver access
logs.
