[Perfparse-announce] New Version 0.104.7

[Ben C. <be...@cl...>]

Dear Users.

We are delighted to release next version, 0.104.7.  This contains mostly 
fixes.  Including the CGI 'Error 500' to which some of you have 
reported.  A fix to a compilation bug on Solaris and a runtime bug for 
those who were already using any perfparse-log2* executable reading from 
a socket connected to perfparsed.

Full Changelog is shown at end of posting.

Please report any problems back to us, we will endeavour to fix your 
problems before adding new features :)

An important new feature, explained by Yves:

With perfparse-0.104.7 comes a very exciting feature : the new storage 
module for gnuplot allows you to easily make csv data files that gnuplot 
understands. With this module, you will be able to make multi-line 
graphs. Many were dreaming of such a feature!

You only need to run perfparsed with the file_output storage module enabled.

However, that module is a quick hack to show what perfparse can do with 
gnuplot and without database support. There are a lot of things to 
improve here, like for example to run gnuplot from the module instead of 
you running interactively.  If you want to help, the gnuplot module is 
150 lines of code only (without the comments). Last thing: nothing is 
documented on this feature. Yves will try to write things, but there is 
a lot to do in the documentation. If you think you can help, please drop 
us a mail !

This option will be available for users using MySQL in the near future.

There will be some discussion in the future about whether to use the 
excellent GnuPlot tool as an extra, or even replacement, for the current 
graph drawing code.  If you have an opinion on this tool, please let us 
know your feelings.

Finally a new tool, which at the moment installs into the 'bin' directory:

check_perfparse_version

This will check your perfparse database version is correct, in Nagios 
plugin format.  Although this version only changes on new installations, 
forgetting to run the 'upgrade' may result in permanent loss of data. 
Therefore this is a fail-safe check mechanism.  You may consider 
embedding this as an hourly check in Nagios.
