No.
Here, they are taking the whole message



I dont want that.

e.g.
What I want is following:

when we execute
logger.info(new MyMessage("temp","1234","a...@gmail.com"));

then it should write into a table

name  idemail
temp   1234   a...@gmail.com

Re: How to store custom-message variable values to the database table's column using log4j2

2017-10-10 Thread Matt Sicker 
Are you using ColumnMapping? See <
https://logging.apache.org/log4j/2.x/manual/appenders.html#JDBCAppender>.

See <
https://github.com/apache/logging-log4j2/blob/master/log4j-nosql/src/test/resources/CassandraAppenderTest.xml>
for example usage (even though that uses the CassandraAppender, the same
ColumnMapping element works in JdbcAppender).

We are aware of the end of life status, but it's not a trivial exercise
to upgrade.  Multiple issues have been filed to upgrade log4j in Solr,
this is the one that's left after resolving duplicates:

https://issues.apache.org/jira/browse/SOLR-7887

Presumably we're going to need a new LogWatcher implementation for
log4j2 before we can complete the log4j upgrade.  I know almost nothing
about that code.  SOLR-7887 has a work in progress patch that might
implement that watcher, which I have not looked at in depth yet.

Thanks,
Shawn

Hi Matt/Ralph,



I've created custom-message implementing log4j2's 'message' interface like
following tutorial

https://logging.apache.org/log4j/2.x/manual/messages.html



I've also defined JDBCAppender in lo4j2.xml which writes values from above
message to database table.

I've tried using conversion-pattern %m in the Column configuration but it
stores the whole message.



*Which conversion-pattern to use here to get specific variable values and
writing them in the table's column*?

Re: Upgrade from 2.5 to 2.9.0 and Logstash

You might want to post your config and the precise message along with any
stack trace. You can also set status="DEBUG" on the Configuration element
in the config file.

Re: How to add log level for a specific package in log4j2?

2017-10-10 Thread Asma Zinneera Jabir 
You can add it as below.

loggers = org.apache.parquet
logger.org.apache.parquet.name = org.apache.parquet
logger.org.apache.parquet.level = ERROR

If you need to add more loggers, add it to the loggers separated by a comma
and add two more lines as above to specify the name and level.

How about

?

I use Log4j 2.9.1 with the XML configuration. A monitorInterval is
specified in the XML config in order to reconfigure log4j, e.g. for
debugging.
Besides the XML configuration some loggers and appendes are created
dynamically in Java.

Problem:
The dynamically added loggers and appenders are lost after the XML
configuration has been reloaded.


LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
Configuration config = ctx.getConfiguration();

Appender appender = RollingFileAppender.newBuilder()...
config.addAppender(appender);

LoggerConfig loggerConfig = LoggerConfig.createLogger(...)
loggerConfig.addAppender(appender, null, null);
config.addLogger(loggerName, loggerConfig);
ctx.updateLoggers();


Could the dynamically added loggers/appenders be isolated from the
automatic reconfiguration?
Is there another way to add them programamtically?

Thanks,
Michael
