I came across an issue with Apache 2.2 on freebsd 8.2 where munin wasn’t graphing the Apache data. (apache_accesses, apache_processes and apache_volume )
When I tailed the munin error log I found this error.
[www@itkylin.com~]#tail /var/log/munin/munin-node.log
munin UserAgent not found at apache_volume line 86.
With some researching on google I found this nice munin command to tell me more about how to setup munin. IE what we can install on freebsd.
/usr/local/sbin/munin-node-configure –suggest
The output gave us “LWP::UserAgent not found”. which means, install Perl’s libwww.
To fix this error we install p5-libwww
[www@itkylin.com~]#cd /usr/ports/www/p5-libwww/
[www@itkylin.com~]#make install clean
Restart munin and everything should now work.
[www@itkylin.com~]# ./usr/local/etc/rc.d/munin-node restart
