Arch Linux

Description:

I kept the default munin configuration after 2.0.4 was pushed to [extra], and I noticed that it now produces a huge munin-graph.log file and a bigger than necessary munin-html.log file.

More specifically:

munin-graph.log
---------------

Previously it would log about 36 lines per run; now it's sticking 2642 lines into the log file each time it runs.

For each graph it would output something like this:

2012/08/19 03:15:08 [INFO] Graphed service [host identifier]:uptime (0.11 sec)

But now:

2012/08/25 02:45:22 Request path is /host/path/uptime-year.png
2012/08/25 02:45:22 asked for (host, path, uptime, year)
2012/08/25 02:45:22 Starting munin-graph
2012/08/25 02:45:22 [INFO] Looking into drawing /usr/share/munin/www/host/path/uptime-year.png
2012/08/25 02:45:22 [INFO] Graphed service host;path:uptime (0.03 sec for 1 graphs)
2012/08/25 02:45:22 Munin-graph finished (0.03 sec)
2012/08/25 02:45:22 X-Munin-Request: 240/0

(the above repeats 7 more times; for uptime-month.png, uptime-week.png, uptime-day.png -- for some reason, along with uptime-year.png, these appear twice in the same run)

The amount of log information generated is about 50MB/day with 33 plugins enabled and a total of 132 generated graph images. Rotated weekly, this goes up to ~350MB. (More plugins enabled would mean even bigger log files.)

munin-html.log
--------------

This one went from storing 4 lines of text per run to about 171. The extra lines repeat the following two warnings:

[PERL WARNING] Use of uninitialized value in string eq at /usr/share/perl5/vendor_perl/Munin/Master/HTMLConfig.pm line 461.
[PERL WARNING] Use of uninitialized value in string eq at /usr/share/perl5/vendor_perl/Munin/Master/HTMLConfig.pm line 488.

Line 461 in that file is -> if ($config->{'graph_strategy'} eq "cgi") {
Line 488 in that file is -> next if ($config->{'graph_strategy'} eq "cgi");

I guess, in both cases, it doesn't appreciate having graph_strategy commented out in munin.conf.

Additional info:
* package version(s): munin{,-node} 2.0.4-1
* config and/or log files etc. -> default munin.conf with one host added


Steps to reproduce:

- Leave html_strategy cgi commented
- Watch /var/log/munin/munin-graph.log grow larger and larger
