[[introduction]]
== Introduction

Because NTP is a widely-used an well-established service, people
who write tools for system administrators frequently have
features and plugins designed to help you work with it. This
page collects some references that may be useful.

The https://www.wireshark.org/[Wireshark] protocol analyzer has
support for displaying NTP packets with the fields broken out
and interpreted.

[[nagios]]
== Nagios

The https://www.nagios.org/[Nagios] monitoring suite has native
support for querying NTP servers.  The 'check_ntp_peer' and
'check_ntp_time' programs may be of particular interest.

[[netdata]]
== Netdata

The https://github.com/firehol/netdata/wiki[Netdata] monitoring
solution has native support for realtime monitoring of ntpd,
among a vast number of other system metrics.
