=head1 NAME |
| 5 |
|
| 6 |
if - Multigraph plugin to monitor network wired and wireless interfaces |
| 7 |
|
| 8 |
=head1 INTERPRETATION |
| 9 |
|
| 10 |
In the general graphs made key fields for each interface, a subsidiary graphs for each interface there are detailed |
| 11 |
|
| 12 |
This plugin displays the following charts: |
| 13 |
Traffic, bytes |
| 14 |
Traffic, packets |
| 15 |
Average packet size |
| 16 |
Interface errors |
| 17 |
WiFi interface errors |
| 18 |
WiFi interface signal and noise |
| 19 |
WiFi interface link quality |
| 20 |
Interface utilisation |
| 21 |
|
| 22 |
Virtual interface names prefixes with '~' |
| 23 |
|
| 24 |
=head1 CONFIGURATION |
| 25 |
|
| 26 |
This plugin is configurable environment variables. |
| 27 |
env.exclude - Removing interfaces from graphs, default empty |
| 28 |
env.include - Includes interfaces into graphs, default empty |
| 29 |
env.if_max_bps - Maximum interface bps. Avialable suffixes: k, M, G, default empty |
| 30 |
env.protexct_peaks - Protect graph peaks, default 'no' |
| 31 |
env.min_packet_size - Minimal network packet size, default 20 |
| 32 |
Example: |
| 33 |
[if] |
| 34 |
env.exclude lo |
| 35 |
env.include wlan0 tun0 |
| 36 |
env.wlan0_max_bps 54M |
| 37 |
env.eth0_max_bps 1G |
| 38 |
env.protect_peaks yes |
| 39 |
|
| 40 |
Protect peak: |
| 41 |
1. Protect wifi signal and noise values, all values > 0 print as NaN |
| 42 |
2. protect all percent values. All values > 100 print as NaN |
| 43 |
3. Protect bps values. env.if_max_bps must be set. All values > max_bps prints as 0 |
| 44 |
4. protect pps values. env.if_max_bps must be set. All values > max_bps/minimal packet size, prints as 0 |
