Attachment: CustomLogger.java
> Custom Logger with restrictions on existing methods
> ---------------------------------------------------
>
> Key: LOG4J2-695
> URL: https://issues.apache.org/jira/browse/LOG4J2-695
> Project: Log4j 2
> Issue Type: Bug
> Components: API

> I have been looking at the Custom/Extended logger discussions. But none of them seems to fulfil what i am looking for.
> 1) I want custom methods as below:
> private static CustomLogger logger = CustomLogger.getLogger(AppAsyncMain.class);
>
> logger.info( transaction_id, app_name + event_name +
> "inside the loop" + "inside the loop of the sample app" +
> "success" + "looped in" + "loop_count" +
> String.valueOf(i));
>
> log:
> 2014-06-30 16:09:28,268 log_level="INFO" thread_name="main" class_name="com.custom.samplelog4j.AppAsyncMain" transaction_id="79ea1071-9565-405a-aa18-75d271694bf2" event_id="dd5c69c0-4400-41fd-8a2e-5d538d8e8c9b" app="Sample Logging SDK App" event_name="Sample Event" action="start of sample app" desc="start of api" result="success" reason="start" token="abcdefg" alias="abc@gmail.com"
>
> 2) I want to show warning in existing logger methods so the teams using the custom logger doesn't use these methods other than for testing:
> logger.info("start of statement");
>
> log:
> 2014-06-30 16:12:31,065 log_level="INFO" thread_name="main" class_name="com.custom.samplelog4j2.AppAsyncMain" start of statement customlogger_warning="method not recommended for production use"
>
> 3) Custom validations for the fields:
> private static String validateFields(String app_name, String event_name,
> String action, String desc, Result result, String reason) {
> String validateStatus = "";
> if (!ValidateAppName(app_name)) {
> validateStatus = "app_name";
> } else if (!ValidateEventName(event_name)) {
> validateStatus = "event_name";
> } else if (!ValidateAction(action)) {
> validateStatus = "action";
> } else if (!ValidateDesc(desc)) {
> validateStatus = "desc";
> } else if (!ValidateReason(result, reason)) {
> validateStatus = "reason";
> }
> return validateStatus;
> }
> Options tried:
> 1) a) extended ExtendedLoggerWrapper
> b) created the map of the Custom logger
> c) This option was failing because of "writing to a closed appender"
> d) Attached is the code "CustomLogger.java"
>
> 2) Modified the AbstractLogger in Trunk and added the below methods:
> @Override
> public void info(final String message) {
> String updtMessage = message + " amexlogger_error=\"Incorrect method used\"";
> logIfEnabled(FQCN, Level.INFO, null, updtMessage, (Throwable) null);
> }
> public void info(final String transactionId, final String app_name, final String event_name, final String action, final String desc, final String result, final String reason, final String... moreFields) {
> String message = "transaction_id=" + transactionId + " " + "app_name=" + app_name + " " + "event_name=" + event_name + " " + "action=" + action;
>
> logIfEnabled(FQCN, Level.INFO, null, message, (Throwable) null);
> }
> I don't want to modify the methods inside the log4j-api.
>
> Please help me with the correct approach on how to use log4j2 for this usecase.
> Thanks
