You can view diagnostic information about NTP servers and pools in a network template and on a Kaspersky NGFW device:
To view diagnostic information in a network template, select the Network templates tab in the menu, click a network template, and select the NTP section.
To view diagnostic information on a Kaspersky NGFW device, go to the Devices menu section, click a Kaspersky NGFW device, and select the NTP section.
The NTP server or pool with which the time on the device is synchronized is displayed in the Synchronized with line.
The time of the last date and time update request to all configured NTP servers is displayed in the Update requested line. The time of the last date and time update received from all configured NTP servers is displayed in the Update received line.
The following information is displayed in the table:
MS is the state of the NTP server. The following values are possible:
CurrentBest indicates the NTP server or pool that is currently considered the best available time source among all configured NTP servers. The NTP client uses this server for time synchronization.
Combined indicates an NTP server or pool whose data has been successfully combined with data from other servers to get more accurate time.
NotCombined indicates an NTP server or pool whose data has not been combined with data from other servers. This may be due to the fact that the server is considered unreliable, its latency is too high, or its time is significantly different from the time of other servers.
MayBeInError indicates an NTP server or pool that may transmit an incorrect time value and is not used until more information is received.
TooVariable indicates a server with a delay or variability that is too great.
Unusable indicates an NTP server or server pool that cannot be used for time synchronization. Such a server may be, for example, unavailable or experiencing connectivity problems.
Preferred is the server or pool that is the device's first choice for getting time data from.
Pool or server is the IP address or domain name of the NTP server or pool.
Stratum indicates how far removed the NTP server is in terms of hierarchy tiers from the reference time source.
Poll is the interval at which the device contacts the NTP server or pool for synchronization.
Reach is an octal value that indicates the success or failure of the eight latest attempts to synchronize with the NTP server.
Last RX is the time in seconds elapsed since the last packet with time information was received from the NTP server or pool.
Last sample is the time of the last successful measurement of the difference between the local time and the NTP server time.
