Operations

Log Message¶

This operation is similar to the Core Logger with the addition that it supports optionally using a configuration object

Parameters supported:

Name	Default	Optional	Description
Log Level	INFO	Yes	Log level
Category		Yes	Log Category
Message		No	Log Message

This operation is designed to log a structured data message using a log4j MapMessage record.

If the data map provided includes any map or collection, it will be flattened as per example below:

{
  "hello": "world",
  "car": {
    "color": "blue",
    "miles": 10000,
    "tags": ["fast","large"]
  }
}

will be transformed into

{
  "hello": "world",
  "car.color": "blue",
  "car.miles": 10000,
  "car.tags.[0]": "fast",
  "car.tags.[1]": "large"
}

This operation is especially useful when combined with the JSON layout as all field will be inlined in the JSON record.

Additionally, if the 'Include location' parameter is set (which is the default), it will add the following data to the map:

Key	Value
code.location.rootContainerName	Root container location (typically the flow)
code.location.filename	Code file name
code.location.line	Line number in code file

Name	Default	Optional	Description
Log Level	INFO	Yes	Log level
Category		Yes	Log Category
Prefix		Yes	If this is set, all map keys will be prefixed with that value separated by a dot
Include code location	true	Yes	If this is set, code location data will be added to map
Data Map		No	Data Map to log
