Munin contributed plugins

#!/usr/bin/env python3

# -*- python -*-

# This plugin graphs the rate of sent, received, ignored, and dropped

# NTP packets for an ntpd process. Similarly to the if_ plugins,

# received packets are graphed as negative values, and sent packets

# are graphed as positive values. Ignored and dropped packets are

# graphed as positive values.

#

# The values are retrieved using ntpq or ntpdc, depending on the

# version of the NTP distribution.

#

# Symlink this plugin into the node's plugins directory (like

# /etc/munin/plugins).
