NAME
       ntp_decode - ntpd Event Messages and Status Words


INTRODUCTION
       This  page  lists  the  status  words, event messages and error codes used for ntpd
       reporting and monitoring. Status words are used to display the  current  status  of
       the  running  program.  There  is one system status word and a peer status word for
       each association. There is a clock status word for each association that supports a
       reference  clock.  There  is  a  flash code for each association which shows errors
       found in the last packet received (pkt)  and  during  protocol  processing  (peer).
       These are commonly viewed using the ntpq program.

       Significant  changes  in  program state are reported as events. There is one set of
       system events and a set of peer events for each association. In addition, there  is
       a  set of clock events for each association that supports a reference clock. Events
       are normally reported to the protostats monitoring file and optionally to the  sys-
       tem log. In addition, if the trap facility is configured, events can be reported to
       a remote program that can page an administrator.

       This page also includes a description of the error messages produced by the Autokey
       protocol. These messages are normally sent to the cryptostats monitoring file.

       In the following tables the Code Field is the status or event code assigned and the
       Message Field a short string used for display and event reporting. The  Description
       field  contains  a longer explanation of the status or event. Some messages include
       additional information useful for error diagnosis and performance assessment.


SYSTEM STATUS WORD
       The system status word consists of four fields LI (0-1), Source (2-7), Count (8-11)
       and  Code  (12-15).  It is reported in the first line of the rv display produced by
       the ntpq program.

       The Count Field displays the number of events since the last time the code changed.

PEER STATUS WORD
       The  peer  status  word  consists of four fields: Status (0-4), Select (5-7), Count
       (8-11) and Code (12-15). It is reported in the first line of the rv associd display
       produced by the ntpq program.


       +--------------------+---------------------+---------------------+-----------------+
       |     Status         |      Select         |       Count         |       Code      |
       +--------------------+---------------------+---------------------+-----------------+
       The  Status Field displays the peer status code bits in hexadecimal; each bit is an
       independent flag. (Note this field is 5 bits wide, and combines with the the 3-bit-
       wide Select Field to create the first full byte of the peer status word.) The mean-
       ing of each bit in the Status Field is listed in the following table:


       +---------------+--------------------+----------------------------------+----------+
       |    Code       |      Message       |      Description                 |          |

       +---------------+--------------------+----------------------------------+----------+
       The Select Field displays the current selection status. (The T Field in the follow-
       ing  table gives the corresponding tally codes used in the ntpq peers display.) The
       values are coded as follows:


       +---------+-------------------+-------+--------------------------------------------+
       | Code    |  Message          |  T    | Description                                |

       +---------+-------------------+-------+--------------------------------------------+
       The Count Field displays the number of events since the last time the code changed.
       Upon reaching 15, subsequent events with the same code are ignored.

       The Event Field displays the most recent event message coded as follows:

CLOCK STATUS WORD
       The  clock status word consists of four fields: Unused (0-7), Count (8-11) and Code
       (12-15). It is reported in the first line of the clockvar associd display  produced
       by the ntpq program.


       +---------------------+-----------------------+---------------------+--------------+

       +---------------------+-----------------------+---------------------+--------------+
       The Count Field displays the number of events since the last lockvar command, while
       the Event Field displays the most recent event message coded as follows:


       +-------------+------------------------+-----------------------------------+-------+
       |   Code      |    Message             |    Description                    |       |

       +-------------+------------------------+-----------------------------------+-------+
       When the clock driver sets the code to a new value, a clock_alarm (11)  peer  event
       is reported.


FLASH STATUS WORD
       The flash status word is displayed by the ntpq program rv command. It consists of a
       number of bits coded in hexadecimal as follows:

KISS CODES
       Kiss codes are used in kiss-o'-death (koD) packets, billboard displays and log mes-
       sages.  They  consist  of a string of four zero-padded ASCII charactes. In practice
       they are informal and tend to change with time and implementation.  Some  of  these
       codes can appear in the reference identifier field in ntpq billboards. Following is
       the current list:
