Is there any log limit for printing payload in mule-3 or Mule-4

Question

I am trying to print huge json with base64 content in the logger. I am suspecting that entire payload is not getting printed. Because json closed tags are not appearing at the end of payload. take a look at the payload that is getting printed

 {"emailSubject": "TEST : (DocID=000100) (UPI=xxxxyy) Request : Arun, Prema","status": "sent","compositeTemplates": [{"serverTemplates": [{"sequence": 1,"templateId": "0D8DA18B"}],"document":{"name" : " LOA","display" : "inline","documentId" : "1","documentBase64":"JVBERi0.....................................

and the closing double quotes are also not there at the ending. what can I do to print entire payload. base64 content is at the ending tag "documentBase64". we are using mule on-prem not using cloudhub logging

Answer 1

You are using the wrong tool for that purpose. Using a logger to print big payloads may cause issues like high memory usage, high CPU usage, or truncated/corrupted message. The expected usage of a logger like log4j2 is to print log messages to track what the application is doing, not auditing huge payloads. If you want to send payloads somewhere, like a file or Splunk, use a connector. You could find an existing one or need to create your your own.
