Functionality

Provides plugins for checking and measuring Network Time Protocol (NTP) servers.

Usage

check-ntp.rb

Check the synchronization state of the local NTP server.

parameters:

  • warn: Maximum offset in ms for warning state (default: 10)
  • crit: Maximum offset in ms for critical state (default: 100)
  • stratum: Maximum stratum value (default: 15)
  • unsynced_status: Default status when unsynced (default: UNKNOWN)

metrics-ntpdate.rb

Get metrics from ntpdate.

parameters:

  • server: Comma separated list of NTP server(s) to measure (default: localhost)
  • scheme: Prefix for metrics (default: hostname)

values:

  • offset: Time difference between server and source (unit: ms)
  • delay: Roundtrip time from server to source (unit: ms)

metrics-ntpstats.rb

Get metrics from ntpstats.

parameters:

  • host: Target host (default: localhost)
  • scheme: Prefix for metrics (default: hostname)

values:
