    hwmonitor

    Show server load-average chart and run pre-define command remotely

    I'm a HW Support and used cacti, zabbix, but they are too "strong", sometimes I just want to know server "worked fine", and show me a basicly load-average chart, that's enough. And the other hand, I need run command (like: "top", "iostat", "date" etc.) remotely and show it out to the webpage. The hwmonitor(writen in C) is a simple daemon, you can define some command-name(like: show_top= top -b -n1), telnet to this daemon and input your def-command(like: show_top), hwmonitor will return the info. And hwclient(include in this project, writen in C) connect to hwmonitor, input a define command-name to get server load-average and IO-idle each 60 seconds(you can change it) into a text file. hwgraphic (include in this project, writen in PHP) read the text file(generated by hwclient) and show the load-average chart and IO-idle chart.
