View Source util_log_formatter (util v1.1.5)
Log formatter Derived from //kernel/logger/logger_formatter
This implementation is copied from logger_fomatter.erl and adds the following features:- time_offset = none
- when provided, no time zone offset will be written to the log.
- time_unit = second | millisecond | microsecond
- controls time stamp granularity in the log.
- report_prefix = string()
- inserts given prefix before
msgfor logging a report (default: "\n"). - report_term_depth = integer()
- max depth of terms included in the reports. Use
infinityfor unlimited (default: 50)
Report printing is modified to align keys in a report to the right.
Additional template formatting atoms:- lev
- prints "[X]" to the log to indicate the log level, where
X` is the first capitalized letter of the log level.</dd> <dt>LEVEL</dt><dd>same aslevel' but is printed in upper case. - modline
- prints 'Module:Line' to the log.
- regpid
- prints:
*- if the registered name of the caller's pid matches caller's module name.
RegisteredName- of the calling process
X.Y.Z- pid of the caller with leading
0.stripped. - regname
- prints
<RegisteredName>of the process or its pid if the process is not registered
