NTP MIB Object Definitions
•
ntpSysLeap
: two-bit code warning of an impending leap second to be inserted in the NTP
timescale.
•
ntpSysStratum
: indicating the stratum of the local clock. 0, unspecified; 1, primary refer-
ence (e.g., calibrated atomic clock, radio clock); 2 to 255, secondary reference (via NTP).
•
ntpSysPrecision
: signed integer indicating the precision of the various clocks, in seconds to
the nearest power of two.
•
ntpSysRootDelay
: the total roundtrip delay to the primary reference source at the root of
the synchronization subnet, in seconds.
•
tpSysRootDispersion
: the maximum error relative to the primary reference source at the
root of the synchronization subnet, in seconds. Only positive values greater than zero are
possible.
•
ntpSysRefId
: the particular reference clock.
In the case of stratum 0 (unspecified) or
stratum 1 (primary reference source), this is a pour-octet, left-justified, zero-padded ASCII
string. In the case of stratum 2 and greater (secondary reference) this is the four-octet Internet
address of the peer selected for synchronization.
•
ntpSysRefTime
: the local time when the local clock was last updated. If the local clock as
never been synchronized, the value is zero.
•
ntpSysPoll
: the minimum interval between transmitted messages, in seconds as a power of
two. For instance, a value of six indicates a minimum interval of 64 seconds.
•
ntpSysPeer
: the current synchronization source. Usually this will be a pointer to a structure
containing the peer variables. The special value NULL indicates there is no currently valid
synchronization source.
•
ntpSysPhase
: The system clock offset per selected source. (needs verification)
•
ntpSysFreq
: The system clock frequency correction per ntpd. (needs verification)
•
ntpSysError
: The current system error per ntpd? (needs verification)
•
ntpSysClock
: the current local time. Local time is derived from the hardware clock of the
particular machine and increments at intervals depending on the design used.
•
ntpSysSystem
: the type of local Operating System.
•
ntpSysProcessor
: the type of the local Processor.
