=head1 NAME
if - Multigraph plugin to monitor network wired and wireless interfaces
=head1 INTERPRETATION
In the general graphs made key fields for each interface, a subsidiary graphs for each interface there are detailed
This plugin displays the following charts:
2013-06-18 14:59:53 +02:00
Traffic, bit
2010-07-08 19:33:14 +02:00
Traffic, packets
Average packet size
Interface errors
WiFi interface errors
WiFi interface signal and noise
WiFi interface link quality
Interface utilisation
2010-07-16 11:28:13 +02:00
Virtual interface names prefixes with '~'
2010-07-08 19:33:14 +02:00
=head1 CONFIGURATION
This plugin is configurable environment variables.
env.exclude - Removing interfaces from graphs, default empty
env.include - Includes interfaces into graphs, default empty
env.if_max_bps - Maximum interface bps. Avialable suffixes: k, M, G, default empty
env.protexct_peaks - Protect graph peaks, default 'no'
env.min_packet_size - Minimal network packet size, default 20
Example:
[if]
env.exclude lo
env.include wlan0 tun0
env.wlan0_max_bps 54M
env.eth0_max_bps 1G
env.protect_peaks yes
Protect peak:
2010-07-16 11:28:13 +02:00
1. Protect wifi signal and noise values, all values > 0 print as NaN
2. protect all percent values. All values > 100 print as NaN
2010-07-08 19:33:14 +02:00
3. Protect bps values. env.if_max_bps must be set. All values > max_bps prints as 0
4. protect pps values. env.if_max_bps must be set. All values > max_bps/minimal packet size, prints as 0
