The application will look for the config .jlv.jsonc in the working directory or in the home directory:
$PWD/.jlv.jsonc;$HOME/.jlv.jsonc.
It's also possible to define the path to the configuration using "-config" flag.
The Json path supports the described in yalp/jsonpath syntax.
Example configuration: example.jlv.jsonc.
JSON Log Viewer can handle a variety of datetime formats when parsing your logs.
The value is formatted by default in the "RFC3339" format. The format is configurable, see the time_format field in the config.
This will return the exact value that was set in the JSON document.
This is a "smart" parser. It can accept an integer, a float, or a string. If it is numeric (1234443, 1234443.589, "1234443", "1234443.589"), based on the number of digits, it will parse as seconds, milliseconds, or microseconds. The output is a UTC-based RFC 3339 datetime.
If a string such as "2023-05-01T12:00:34Z" or "---" is used, the value will just be carried forward to your column.
If you find that the smart parsing is giving unwanted results or you need greater control over how a datetime is parsed, considered using one of the other time formats instead.
This will attempt to parse the value as number of seconds and render as a UTC-based RFC 3339. Values accepted are integer, string, or float.
Similar to secondtime, this will attempt to parse the value as number of milliseconds. Values accepted are integer, string, or float.
Similar to secondtime and millistime, this will attempt to parse the value as number of microseconds. Values accepted are integer, string, or float.
