SIBISH BASHEER commented on LOG4J2-695:
---------------------------------------
Hi Ralph,
Yeah, sorry missed that point. So the other methods will still show up but
won't log any data because of filter. OK, will try that method as well and will
see if my architects like it.
Meanwhile, i am struck with a fundamental performance issue. Old log4j
synchronous logging is twice faster than the Async logger with exact same
validations, uuid generation etc. :-(
If i cannot justify the performance, i am struck again. log4j2 with disrupter
is supposed to be insanely fast.
Can you please help. I have attached the comparison classes and its
corresponding xmls.

> 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:
> {code}
> 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));
> {code}
>
> log:
> {code}
> 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="a...@gmail.com"
> {code}
>
> 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:
> {code}
> logger.info("start of statement");
> {code}
>
> log:
> {code}
> 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"
> {code}
>
> 3) Custom validations for the fields:
> {code}
> 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;
> }
> {code}
> Options tried:
> 1.
> * extended ExtendedLoggerWrapper
> * created the map of the Custom logger
> * This option was failing because of "writing to a closed appender"
> * Attached is the code "CustomLogger.java"
>
> 2. Modified the AbstractLogger in Trunk and added the below methods:
> {code}
> @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);
> }
> {code}
> 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
