# 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).
