Remko Popma updated LOG4J2-1244:
--------------------------------
Description:
It will be helpful to provide a way to customize header and footer in
JSONLayout in Log4j 2.
For instance user is writing a logging application which logs requests and
responses to/from a server to log files in JSON format. Now user also wants to
log server specific information in each log file but since it will be common
for all request/response, it is not desired to be logged with each log entry so
user wants to add server specific common information at start of the file. As
header in JSON format or in this use case. This will be followed by each
request and response logged as a JSON array element. And at rollover this JSON
array and main JSON object (which contains header and JSON array) should be
closed with help of footer.
A typical file will be something like ...
{code}
{"Header":{"ServerName":"MyAppServer"},"LogEntries":[
{"Message":"Request
message1","RequestingAddress":"127.0.0.1","TimeStamp":"2016-01-05_07-24-59"},
{"Message":"Request
message1","RequestingAddress":"127.0.0.1","TimeStamp":"2016-01-05_07-24-59"},
{"Message":"Request
message1","RequestingAddress":"127.0.0.1","TimeStamp":"2016-01-05_07-24-59"},
{"LogEndMarker":"END"}
]}
{code}
