# You may set it to undef to prevent calling Sys::Syslog::setlogsock at all

# Plugins
# Plugins extend NfSen for the purpose of:
# Periodic data processing, alerting-condition and alerting-action
# For data processing a plugin may run for any profile or for a specific profile only.
# Syntax: [ 'profile list', 'module' ]
# profile list: ',' separated list of profiles ( 'profilegroup/profilename' ),
# or '*' for any profile, '!' for no profile
# module: Perl Module name, equal to plugin name
# The profile list '!' make sense for plugins, which only provide alerting functions
#
# The module follows the standard Perl module conventions, with at least one
# function: Init(). See demoplugin.pm for a simple template.
#
# A file with the same name in the FRONTEND_PLUGINDIR and .php extension is automatically
# recongized as frontend plugin.

# Plugins are installed under
# $BACKEND_PLUGINDIR and $FRONTEND_PLUGINDIR

# For the NfSen simulator include the section below.

######################################################
#
# Nfsen Simulator
# The simulator requires, that you have already installed
# and configured NfSen. The simulation is based on already
# pre-colleted data, which you may get from another live
# NfSen system.
#
# Steps to setup the NfSen simulator:
# 1. Configure the sources of the live profile with the
# same names of the NfSen system, you take netflow data
# for the simulation. Set the port for each netflow source
# to 0 to prevent a collector to be started.
# Install NfSen with this config in a seperate directory
# 2. Copy the pre-collected data into the appropriate
# netflow directory of the live profile.
# 3. Configure the simulator using the parameters below
# Enable Simulation mode => $SIMmode = 1
# Configure the time window of the pre-collected data.
# tstart => Start of time window. yyyymmddhhmm
# tbegin => Optional parameter. Start of simulation
# profile exists already between tstart - tbegin
# tend => End of time window. yyyymmddhhmm
# cycletime => simulation time in seconds of a 5min slot
# Setting cycletime = 0 processes the cycles as fast as
# possible. Please note, if you test plugings, your
# cycletime needs to be at least the time required to
# process all plugins.
# 4. Start nfsen: ../nfsen start
# Simulation starts
#
# The simulator runs from tstart to tend and stops when tend
# is reached. You may stop the simulation at any given time
# using ./nfsen stop. To continue the simulation start NfSen
# again: ./nfsen start. You may reset the simulator at any
# given time using ./nfsen abort-reset. This stops the sumulation
# and rolls back to tstart. All profiles/alerts are deleted,
# so you may start from scratch again.
#
# Configure simulator parameters
#
# $SIMmode = 1;
# %sim = (
# 'tstart' => '200707100000', # Simulation data available from July 10th 2007 00:00
# 'tbegin' => '200707110000', # Simulation begins at July 11th 2007 00:00
# 'tend' => '200707112355', # Simulation ends at July 11th 2007 23:55
# 'cycletime' => '30', # 30s per 5min slot
# );
