Ie, poll 10 is 2^10 sec=1024 seconds. >interval ? What are the unit of measurement? which output will be >useful for monitoring potential problems? Probably offset. But if the system is being polled, ntp is probably working. Ie, if you see the time between entries to become longer than hours, then there are problems. >thanks for the help _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
