|

# Plugin to monitor the amavis mail filter for Debian
|
||||
# (based upon a plugin authored by Geoffroy Desvernay)
|
||||
#
|
||||
# This plugin is built and tested on Debian Etch using:
|
||||
# munin 1.2.5-1
|
||||
# amavisd-new 2.4.2-6.1
|
||||
#
|
||||
# With some minor modification it should also work on non-debian systems
|
||||
# This, however, is up to you
|
||||
#
|
||||
# Munin graph will sum up: Passed CLEAN, Blocked VIRUS, Blocked SPAM, Other
|
||||
#
|
||||
# Parameters understood:

||||
# config (required)
|
||||
# autoconf (optional)

#

# Config variables:
|
||||
# AMAVIS_LOG - file where amavis logs are written
|

# STATEFILE - file which is needed to keep track of AMAVIS_LOG
|
||||
# LOGTAIL - location of logtail
|
||||
# BC - location of bc
|
||||
#
|
||||
# Enjoy!

# Plugin to monitor amavisd-new statistics. Values are retrieved by querying
|
||||
# the BerkeleyDB database 'snmp.db', in which amavisd-new stores its
|
||||
# statistics.
|
||||
#
|
||||
# The plugin requires the Perl module BerkeleyDB.
|
||||
#
|
||||
# To use, setup /etc/munin/plugin-conf.d/amavis e.g. as follows:
|
||||
#
|
||||
# [amavis_*]
|
||||
# env.amavis_db_home /var/lib/amavis/db
|
||||
# user amavis
|
||||
#
|
||||
# Where env.amavis_db_home is the path to the amavisd-new BerkeleyDB files
|
||||
# (/var/amavis/db by default).
|
||||
#
|
||||
# Then create symlinks in the Munin plugin directory named "amavis_time",
|
||||
# "amavis_cache" and "amavis_content", or use munin-node-configure.
|
||||
#
|
