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 reference (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.
