Ignite Logging and custom Log4j2 appender issue

["Mitchell Rathbun (BLOOMBERG/ 731 LEX)" <mr...@bloomberg.net>]

I have gotten this to work where the IGNITE appender is being used for Ignite logs. However, I am having a lot of issues related to ActLogAppender, which is a custom appender, working with Ignite. If I set the gridLogger to use Log4J2Logger at all, I continually see:

2020-02-14 13:25:19,199 INFO  STDERR [Thread-2] {} 2020-02-14 13:25:19,197 Log4j2-TF-3-AsyncLoggerConfig-2 ERROR Attempted to append to non-started appender ActLogAppender

I have verified that the appender is started before I see this issue. This log line is written at the beginning of the log file, overwriting the initial log statements. This makes me think that there are two separate loggers or appenders. Either way, this does not work as expected when integrating with Ignite. Any advice/ideas would be appreciated, as I would like to set Ignite's log level to INFO, but can't due to errors with custom appender.

I am hoping to use a separate appender for Ignite logs in my application. In my configuration file, I have:

<asyncLogger name="org.apache.ignite" level="info" additivity="false">
     <appender-ref ref="IGNITE"/>
</asyncLogger>
<asyncRoot level="info">
     <appender-ref ref="MAIN"/>
     <appender-ref ref="ActLogAppender" level="ERROR"/>
 </asyncRoot>

IGNITE and MAIN are both RollingRandomAccessFile appenders pointing to different files. In my java code I have:

File logConfigFile = new File(config.getIgniteGridLoggerXmlPath());
try {
    IgniteLogger logger = new Log4J2Logger(logConfigFile);
    ignCfg.setGridLogger(logger);
} catch (IgniteCheckedException e) {
    LOG.error("Unable to set up IgniteLogger with path {}", logConfigFile, e);
}

When I run my application, Ignite is still sending all of its logs to the same file that MAIN points to. Any idea why this doesn't work? Should the name for the logger be something different than "org.apache.ignite"?

Hello!

Can you please prepare a reproducer project to demonstrate the issue?
Somebody would surely check.
