Usage Guidelines
This command displays event history records. Records will be displayed starting at the specified begin time and will end prior to the specified end time. The begin and end times must be one of the following:
An absolute time in the form “YYYY[/-.]MM[/-.]DD[[ T]hh:mm[:ss]]” (e.g., “2018-07-15T10:43”). Absolute times are interpreted in the local timezone.
The number of seconds since 00:00:00 UTC on January 1st, 1970 (e.g., “1531669380”).
A relative time in the past, in the form “nu”, where “n” is a positive integer and u is one of “s” (seconds), “m” (minutes), “h” (hours), “d” (days), “w” (weeks), “M” (months), or “y” or “Y” (years). When a relative time is specified, all smaller intervals are assumed to be the lowest possible value. That is, “1h” specifies a starting time at the top of the previous hour, “1w” specifies a starting time of 00:00:00 of the day 7 days ago, and “1M” specifies a starting time of 00:00:00 on the first day of the previous month. For example, to display all records from the previous calendar month, use “begin 1M end 0M”. Relative times are interpreted in the local timezone.
The word “now”, “old”, or “end”, referring to the current time, the earliest possible time, or the latest possible time, respectively.
The format option specifies the desired output format. Refer to the history output-format command for supported output formats.
If the where option is specified, only records matching the specified filter will be displayed. Refer to the history filter command for supported filter values.
