pmgraph v0.2 released

[Andreas Östling <andreaso () it su se>]

Hello,

pmgraph v0.2 has been released, get it from 
http://people.su.se/~andreaso/perfmon-graph/

pmgraph is a simple Perl script to create some graphs from Snort's 
perfmonitor preprocessor by using RRDtool. Example output can be found 
on the homepage.

Changes since v0.1:

- Fix so it works correctly on SMP machines

- Clicking on the graphs now take you to a page showing graphs for the
last 12 hours (edit %options in pmgrah.pl to change it) counted from the 
time of generation. Click again to go back to the main page showing 
graphs for the entire perfmon file.

- A warning message will be printed on the HTML page if the last entry 
in the perfmon file is older than an hour at the time of the graph 
generation.

- Print more stuff in the frag graph

- Added contrib/CreateIDSGraphs.sh by Rickard Cedergren.
"CreateIDSGraphs.sh is a wrapper for pmgraph.pl. It's designed for a 
single webserver and a snort multisensor environment."

- By default, the end time in the graphs is now the current time when
the graphs are being generated. Previously, it was the last timestamp
in the perfmonitor file. This is usually no big difference but it makes 
it easier to see if the last perfmonitor entry is old or recent. You 
can edit %options to change to the previous behaviour, which may be 
useful if you're creating graphs from some older perfmonitor file.

- A bunch other small cleanups and fixes


Thanks to Rickard Cedergren, sekure at gmail and Christian Svensson
for their feedback.
