=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:
|
|
Traffic, bit
|
|
Traffic, packets
|
|
Average packet size
|
|
Interface errors
|
|
WiFi interface errors
|
|
WiFi interface signal and noise
|
|
WiFi interface link quality
|
|
Interface utilisation
|
|
|
|
Virtual interface names prefixes with '~'
|
|
|
|
=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:
|
|
1. Protect wifi signal and noise values, all values > 0 print as NaN
|
|
2. protect all percent values. All values > 100 print as NaN
|
|
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
