logrus json formatter

JSON formatted log (log is printed as JSON):

Usage:

go get github.com/GettEngineering/logart/logrus-json-formatter

Default setup:

logrusjsonformatter.Set()

Custom setup:

formatOptions := logrusjsonformatter.DefaultFormatOptions
formatOptions.Option1 = customValue1
formatOptions.Option2 = customValue2
...

logrusjsonformatter.SetCustomized(formatOptions)

Format options allow flexible output configurations:

• TimeLayout - default = RFC3339 (2006-01-02T15:04:05Z07:00)

• LogIDProvider - default = empty string. Actually this is a function that returns string. You can set it to return current "RequestID" or "SessionID" - depends infra code is running in.

Note

JSON formatter is good for log managements systems.

To make the log more "human readable" (for example in dev/stage environments) another formatter should be used, see human readable formatter for more info.
