=head1 NAME
|
||
|
||
multibandwidth - Plugin to monitor the bandwidth between localhost and serveral hosts.
|
||
|
||
=head1 APPLICABLE SYSTEMS
|
||
|
||
All systems with “bash”, and “munin”
|
||
|
||
=head1 REQUIREMENTS
|
||
|
||
bing installed.
|
||
|
||
You can install bing by using (Ubuntu/Debian): apt-get install bing
|
||
|
||
=head1 CONFIGURATION
|
||
|
||
The following is the default configuration
|
||
|
||
[multibandwidth]
|
||
user root
|
||
env.hosts example.org example2.org example3.org
|
||
env.samples 10
|
||
env.small_packet_size 44
|
||
env.big_packet_size 108
|
||
|
||
- env.hosts explanation: hostname or IP of the hosts to calculate the bandwidth.
|
||
|
||
- env.samples explanation: Reset stats after sending samples ECHO_REQUEST packets.
|
||
|
||
- env.small_packet_size explanation: Specifies the number of data bytes to be sent in the small
|
||
packets. The default and minimum value is 44.
|
||
|
||
- env.big_packet_size explanation: Specifies the number of data bytes to be sent in the big
|
||
packets. The default is 108. The size should be chosen so that big packet roundtrip times
|
||
are long enough to be accurately measured.
