NTP behavior explained
Description of NTP daemon behavior and configuration.
Product: Flowmon OS
How often is Flowmon polling NTP servers?
|Steps to Reproduce:|
Flowmon OS uses NTP daemon ntpd. The polling interval of NTP servers is 64 seconds. Intervals shorter than 64 seconds should generally not be used with public servers on the Internet because it might be considered abuse. It might also take some time to restart the NTP daemon, poll the NTP server, and choose the primary one.
NTP daemon automatically chooses the primary NTP server to synchronize with. The algorithm is described in RFC 5905.
NTP configuration can be verified via CLI with the following commands:
