Linux system monitoring with Twitter.

Tag: — tepezcuintle @ 19:58

Here is a little script I wrote to update twitter with server status infomation.
this is not trying to replace Nagios or more advanced server monitoring tools, but if you want to track your own personal server and want a cool hack you can use this script and tweak it.

Please if you do some cool updates could you email it to imrobotmaker@yahoo.com

Thanks
