Description 

Author

Gianluca Zanferrari

This class can display graphs of machine usage in real time.

It can generate HTML and JavaScript code that will use AJAX requests to update the usage of resources of the machine on which PHP is running.

Currently it can display containers with information about the machine memory usage, number of threads, number of users, and used disk space.

Prize: One downloadable copy of Komodo IDE		 Some times it is useful to view information of the state of server resources like for instance CPU, memory or disk usage. However, server resource information varies a lot over time.

This class provides a solution to display the server machine usage using graphs that are updated in real time.

$mon->set_interval(5000); // I set the time interval of measurement to 5 secs

$mon->draw(); // shows the graph in browser

$mon->new_container('used_space'); // initiates the used_space graph

$mon->set_interval(10000); // I set the time interval of measurement to 10 secs

$data = $mon->draw(FALSE); // I store the data in a var for showing it as last graph (usefull for placing graphs in a templete)

$mon->new_container('num_threads'); // initiates the num_threads graph

$mon->set_interval(7000); // I set the time interval of measurement to 7 secs

$mon->draw(); // shows the graph in browser

$mon->new_container('num_users'); // initiates the num_users graph

$mon->set_interval(15000); // I set the time interval of measurement to 15 secs

$mon->draw(); // shows the graph in browser

echo($data); // I show here the 'used_space' graph
