ntp.frequency.offset | gauge | double | [ppm] | development | no | leap.status (string) | The frequency is the rate by which the system s clock would be wrong if chronyd was not correcting it. It is expressed in ppm (parts per million). For example, a value of 1 ppm would mean that when the system’s clock thinks it has advanced 1 second, it has actually advanced by 1.000001 seconds relative to true time. |
ntp.skew | gauge | double | [ppm] | development | yes | | This is the estimated error bound on the frequency. |
ntp.stratum | gauge | int | {count} | development | no | | The number of hops away from the reference system keeping the reference time To read further, refer to https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/ch-configuring_ntp_using_the_chrony_suite#sect-Checking_chrony_tracking |
ntp.time.correction | gauge | double | s | development | yes | leap.status (string) | The number of seconds difference between the system's clock and the reference clock |
ntp.time.last_offset | gauge | double | s | development | yes | leap.status (string) | The estimated local offset on the last clock update |
ntp.time.rms_offset | gauge | double | s | development | no | leap.status (string) | the long term average of the offset value |
ntp.time.root_delay | gauge | double | s | development | no | leap.status (string) | This is the total of the network path delays to the stratum-1 system from which the system is ultimately synchronised. |
