java - Is there a Logback Layout that Creates JSON Objects with Message Parameters as Attributes? -

i want send log events loggly json objects parameterized string messages. our project has lot of code looks this:

string someparameter = "1234"; logger.log("this log message parameter {}", someparameter); 

we're using logback our slf4j backend, , logback's jsonlayout serialize our ilogevent objects json. consequentially, time our log events shipped loggly, this:

{     "message": "this log message parameter 1234",     "level": info,     .... } 

while work, sends different message string every value of someparameter, renders loggly's automatic filters next useless.

instead, i'd have layout creates json looks this:

{     "message": "this log message parameter {}",     "level": info,     "parameters": [         "1234"     ] } 

this format allow loggly group log events message this log message parameter together, regardless of value of someparameter.

it looks logstash's kv filter - there way accomplish task logback, short of writing own layout performs custom serialization of ilogevent object?

you use mapped diagnostic context set stamp each of type of log messages filter on once in loggly.

according source of jsonlayout stamp stored separate value in json.
