Description

OTP logger handler that sends logs to journald

This handler does not provide any overload protection (yet). OTP's built-in logger_olp is not documented (and not really reusable), so we can't use it here.

Implementation of logger handler callbacks. See examples.

Data Types

opts()

opts() = #{socket_path => file:filename_all(), defaults => #{journald_sock:key() => journald_sock:value()}}

Handler's specific options

socket_path - path to journald control socket
defaults - flat key-value pairs which will be mixed-in to every log message (unless overwritten by message's own fields)
