=head1 NAME
|
|
|
|
vhost_requests_ - Wildcard-plugin to monitor http requests by response status code
|
|
to a particular virtual host.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
Example configuration follows.
|
|
|
|
[vhost_requests_*]
|
|
user root
|
|
|
|
Or you can just give read access to munin.
|
|
|
|
An example way to create links for all logfiles (remove the \ from the \$s):
|
|
for f in \$(ls /var/log/apache2/*access_log) ; do ln -s /usr/share/munin/plugins/vhost_requests_ vhost_requests_\$(basename \$f); done
|
|
|
|
Also refer to max_lines, logdir, date_format and status_column below if you have any issue, if
|
|
you're on fedora you'll need to change at least logdir.
|
|
|
|
=head2 ENVIRONMENT VARIABLES
|
|
|
|
This plugin does not use environment variables
|
|
|
|
=head2 WILDCARD PLUGIN
|
|
|
|
This is a wildcard plugin. To show requests by response status code
|
|
on a particular virtual host, link vhost_requests_<desired_access_log_filename> to this file.
|
|
|
|
E.g.
|
|
|
|
# ln -s /usr/share/munin/plugins/vhost_requests_ \
|
|
/etc/munin/plugins/vhost_requests_host.org-access_log
|

|

|
|
# This is the format that date will use to generate access_log like entries
|
|
date_format='+%d/%b/%Y:%R'
|
|
# This is where apache stores logfiles
|
|
logdir=/var/log/apache2
|
|
|
|
# By default process the whole logfile, but you can set a value different than 0 to limit the lines to process.
|
|
# This is useful if the plugin is hurting your performance, a way to calculate this could be:
|
|
# The expected requests in five minutes (you can grab this from the maximum value in the y legend)
|
|
# / 5 * 6 (Because we left the last minute to the next round)
|
|
# times how high can an unexpected peak be (Example 3 times)
|
|
# So, if we have 1000 requests every five minutes max_lines could be:
|
|
# 1000 / 5 * 6 * 3 = 3600
|
|
# It should improve performance because at 1000 requests per 5 minutes you have 288000 per day but it will only read 3600 each time.
|
|
max_lines=0
|
|
# If your http status code comes in a different column, you can change it here: (Assuming ' ' is the column separator)
|
|
status_column=9
