Munin contributed plugins

#!/usr/bin/env python

# Version 0.1 alpha (a.k.a. it has been known to work at least once)

# Get stats from your i2p server ( https://geti2p.net/en/ )

# Create links to this plugin and name them

# - i2p_bps

# - i2p_uptime (not implemented yet)

# Requires BeautifulSoup 4

# Should probably use I2PControl for this instead

# https://geti2p.net/en/docs/api/i2pcontrol
