2 bwmon: Application-level bandwidth monitoring
3 ---------------------------------------------
5 bwmon is an open bandwidth monitoring solution for monitoring per-application
6 bandwidth usage. This can be utilized to better manage and monitor multiple
7 applications running on a single cloud host or a single application running
8 on multiple cloud hosts.
12 * Uses ip_conntrack to track connections
13 * Alternative, cross-platform "pipe" traffic monitor
14 * Easily customizable: Written in Python
15 * Combination of conntrack+pipe monitors possible
16 * Open Framework: Create new monitoring methods
17 * Support for SLA parameter input (bandwidth allocation)
18 * Support for SLA violation notification to external services
19 * Fully documented source code and user manual
23 November 2012 (Version 1.1):
24 In recent kernels, there's no "ip_conntrack" kernel module. As
25 a replacement, bwmon now supports the "conntrack" command-line
26 utility from the "conntrack-utils" package.
28 Make sure to run this command to enable accounting for conntrack
29 (otherwise you might get a "KeyError: 'bytes'" traceback):
31 sysctl -w net.netfilter.nf_conntrack_acct=1
33 Sometimes you have to wait a bit after setting this option to
34 make sure old connections are removed from conntrack's output.
