#
|
||||||
|
# Usage
|
||||||
|
# -----
|
||||||
|
#
|
||||||
|
# The plugin supports two methods for collecting network connection statistics
|
||||||
|
# for the Flash Media Server:
|
||||||
|
#
|
||||||
|
# a.) Using the getServerStats() call of the HTTP API of Flash Media
|
||||||
|
# Administration Server. (This is the default.)
|
||||||
|
#
|
||||||
|
# b.) Using the "netstat" command (available on all sorts of Linux/Unix
|
||||||
|
# operating systems).
|
||||||
|
#
|
||||||
|
# You can configure the plugin to use the latter method by adding the
|
||||||
|
# "use_netstat" variable to the [fms] section in the Munin node plugin config
|
||||||
|
# file.
|
||||||
|
# Eg.
|
||||||
|
# [fms]
|
||||||
|
# env.use_netstat yes
|
||||||
|
#
|
||||||
|
# IMHO the netstat method provides a lot more realistic number for FMS
|
||||||
|
# connections, but I kept the FMS Admin stat method as default since that's
|
||||||
|
# the "Adobe supported" way.
|
||||||
|
#
|
||||||
|
# Moreover you can use the plugin with autoconfiguration or by manually
|
||||||
|
# supplying the required parameters (as variables in the Munin node plugin
|
||||||
|
# config file).
|
||||||
|
#
|
||||||
|
# To use autoconfiguration, you've to run the plugin with root privileges, thus
|
||||||
|
# specify the user in the Munin node plugin config file.
|
||||||
|
# So the least you've to do to make this work is to create an [fms] section
|
||||||
|
# in the node plugin config and add "user root".
|
||||||
|
# Eg.
|
||||||
|
# [fms]
|
||||||
|
# user root
|
||||||
|
#
|
||||||
|
# For autoconfiguration you'll also need the following Perl module:
|
||||||
|
#
|
||||||
|
# Proc::ProcessTable - Perl extension to access the unix process table
|
||||||
|
# http://search.cpan.org/perldoc?Proc::ProcessTable
|
||||||
|
#
|
||||||
|
# On a Debian/Ubuntu system you can install this with the following command
|
||||||
|
# (if APT is configured properly):
|
||||||
|
# apt-get install libproc-process-perl
|
||||||
|
#
|
||||||
|
# In Ubuntu and recent Debian (Lenny and later) versions this is renamed to
|
||||||
|
# libproc-processtable-perl, but for now (at the time of writing)
|
||||||
|
# libproc-process-perl still exists as a dummy package to provide backward
|
||||||
|
# compatibility.
|
||||||
|
#
|
||||||
|
# If you're using the default statistic fetching method (the call to the FMS
|
||||||
|
# Admin Server HTTP API), then you'll also need the following Perl module:
|
||||||
|
#
|
||||||
|
# LWP - The World-Wide Web library for Perl
|
||||||
|
# Used modules: HTTP::Request, LWP::Simple, LWP::UserAgent
|
||||||
|
# http://search.cpan.org/perldoc?LWP
|
||||||
|
#
|
||||||
|
# On a Debian/Ubuntu system you can install this with the following command
|
||||||
|
# (if APT is configured properly):
|
||||||
|
# apt-get install libwww-perl
|
||||||
|
#
|
||||||
|
# For access to the FMS Admin HTTP API you've to publish the "getServerStats()"
|
||||||
|
# call. This means that you've to set "USERS.HTTPCOMMAND_ALLOW" to "true" in
|
||||||
|
# ${FMS_DIR}/conf/fms.ini and in ${FMS_DIR}/conf/Users.xml set the value of the
|
||||||
|
# node "Root/AdminServer/HTTPCommands/Allow" to contain "getServerStats" too
|
||||||
|
# (by default it allows only "ping").
|
||||||
|
#
|
||||||
|
# That's all you've to know about the default (autoconfiguration) method of
|
||||||
|
# running this plugin.
|
||||||
|
#
|
||||||
|
#
|
||||||
|
# As for manual configuration ...
|
||||||
|
#
|
||||||
|
# Follow this example plugin entry in the Munin node plugin config to specify
|
||||||
|
# the FMS Admin server parameters:
|
||||||
|
# [fms]
|
||||||
|
# env.fms_admin_host localhost
|
||||||
|
# env.fms_admin_port 1111
|
||||||
|
# env.fms_admin_username admin
|
||||||
|
# env.fms_admin_password the_admin_password
|
||||||
|
#
|
||||||
|
# Usually fms_admin_host will be localhost (since most people want to monitor
|
||||||
|
# a local instance of FMS), but of course you can set it to any hostname.
|
||||||
|
#
|
||||||
|
# It is strongly advised that you restrict access to the Munin node plugin
|
||||||
|
# config file. It should be readable only by the Munin node daemon since your
|
||||||
|
# FMS admin password should not be accessible by any other user.
|
||||||
|
# In case of Debian/Ubuntu the /etc/munin/plugin-conf.d/munin-node file is
|
||||||
|
# owned by root and the munin-node process runs with root privileges, so the
|
||||||
|
# correct permission is to have the file readable only by root.
|
||||||
|
#
|
||||||
|
# Manual configuration of the netstat method requires the following Munin node
|
||||||
|
# plugin config:
|
||||||
|
# [fms]
|
||||||
|
# env.use_netstat yes
|
||||||
|
# env.fms_host 192.168.0.1
|
||||||
|
# env.fms_port 1935
|
||||||
|
#
|
||||||
|
# The fms_host variable can be skipped if your FMS server listens on all IPs
|
||||||
|
# and not just a single IP.
|
||||||
|
# The fms_port variable must contain a comma-separated list of TCP ports that
|
||||||
|
# your FMS server listens on for incoming connections.
|
||||||
|
# In a default FMS installation this is the 1935 TCP port, but it can be
|
||||||
|
# an arbitrary list (eg. 1935,80,443).
|
||||||
|
#
|
||||||
|
#
|
||||||
|
# Note: autoconfiguration works by going through the list of running processes
|
||||||
|
# and looking for the "fmsadmin" process. If found, we check for the
|
||||||
|
# existence of the "conf/fms.ini" file in the current working directory
|
||||||
|
# of the process. This works fine for all tested FMS versions.
|
||||||
|
# However it is possible that this method is not "universal" enough
|
||||||
|
# (and it requires the plugin to be run as root too) so using the manual
|
||||||
|
# configuration is always there as a backup solution.
|
||||||
|
# The manual config method does not require root privileges for the plugin
|
||||||
|
# to work.
|
||||||
|
#
|
||||||
|
# In case something "bad" happens (eg. plugin is run as non-root and
|
||||||
|
# autoconfiguration is used) the plugin writes some informative message
|
||||||
|
# to stderr to make debugging easier. This should not affect the normal
|
||||||
|
# operation of munin-node since only the stdout of the plugins is used
|
||||||
|
# and that's always kept as munin-node expects.
