OpenNTPD Monitoring

OpenNTPD is a Unix daemon that implements the Network Time Protocol to synchronize the local clock of a computer system with remote NTP servers. It can also act as an NTP server to NTP-compatible clients.

Why use the OpenNTPD Telegraf plugin?

The OpenNTPD collects clock synchronization data so you can configure any necessary offsets for your data.

Typically, machines synchronized over the Internet are accurate to within a few milliseconds; on a LAN, in tens of microseconds. With hardware timestamping, or a hardware reference clock, sub-microsecond accuracy may be possible and could be important when trying to determine the reason for particular issues.

How to monitor OpenNTPD using the Telegraf plugin

Determine the clock synchronization metrics that are critical for your use case. Configure the OpenNTPD plugin to collect those metrics and then point the plugin to InfluxDB to start collecting.

Key OpenNTPD Metrics to use for monitoring

Some of the important OpenNTPD metrics that you should proactively monitor include:

• Tags:
  • remote
  • stratum
• Fields:
  • delay
  • jitter
  • offset
  • poll
  • next
  • wt (weight)
  • tl (trust level)
