The script below lists files in the current directory, which are mrtg
html and image output files. The directory listing is parsed for the
host name and a row for each host is rendered with traffic, cpu, and
uptime html and image files on the corresponding row.
Prior to upgrading from 4.0.6 to 4.2.2 the following script produced
correct output. After upgrading, multiple rows for each host are
output in no specific order. Here's the broken application:
http://tempe.dedserius.com/mrtg/
I took the application to an i386 server configured identically and
tested it and it worked fine:
http://winslow.dedserius.com/mrtg/
