5.3.4.2 Kernel Info
The “Kernel Info” overview shows the current error values of the internal embedded Linux
clock. Both values are internally updated every second.
This screenshot shows a maximum kernel clock error of 23.081 msec (milliseconds). The
estimated error value is 32
μs (microseconds).
The values indicated here are based on the calculation of the NTP service and have no
significance for the accuracy of the Sync Source.
5.3.4.3 Peers
The “Peers summary” is used to track the performance of the configured NTP server/driver
and the NTP algorithm itself.
The information displayed is identical with the information available via NTPQ or NTPDC
programs.
Each NTP server/driver that has been set up in the NTP server configuration is displayed in
the peer information.
The connection status is displayed in the reachability column (not reachable, bad, medium,
and reachable).
The upper picture shows the external NTP server (192.168.180.107) used for synchronization.
A short explanation and definition of the displayed values can be found in Chapter 9.5
Accuracy & NTP Basic Principles
.
The character in the first column on the left presents the current status of the NTP association
in the NTP selection algorithm. A list and description of possible characters can be found in
the Glossary (see
Chapter 9.2 Tally Codes (NTP-specific) ).
