Revision:	1.37
Committed:	Fri Feb 11 14:05:29 2005 UTC (19 years, 8 months ago) by tdb
Branch:	MAIN
Changes since 1.36:	+11 -0 lines
Log Message:	Updates from skel (Daniel Piddock): - Fix overflow in disk inodes on PHP page. - Added code to get passed in variables from the $_GET variable. Makes things work under a pretty default Debian apache2/php4 set up. - Graphs displays "Network IO" in the drop down list, not "Network usage" for consistency with everything else. - Display Swap, memory and disk usage in MB rather than bytes in latest view. - Display uptime in a pretty days/hours/minutes/seconds rather than just seconds, in latest view - Include file system type under Disks in latest view Thanks Daniel!
