Logging configurations

[max010]

Hi,

I am trying to create a solr-.yyyy-MM-dd.log file in the /standalone/log directory.

From the SOLR wiki I have to add:

<logger category="org.apache.solr">

                           <level name="INFO"/>

</logger>

in the standalone.xml.

Do I need to create a new logger?

In the standalone.xml the <root-logger> is defined:

<root-logger>

                <level name="INFO"/>

                <handlers>

                    <handler name="CONSOLE"/>

                    <handler name="FILE"/>

                </handlers>

            </root-logger>

How do I create a new logger that logs output to the solr-.yyyy-MM-dd.log file?

Should I do this below?

<solr-logger>

                <level name="INFO"/>

                <handlers>

                     <handler name="SOLRFILE"/>

                </handlers>

            </solr-logger>

Can anyone please help me with this issue?

Thanks,

Max

You need to create a handler first somethig like this

	<periodic-rotating-file-handler name="SOLRFILE" autoflush="true">
	<level name="DEBUG"/>
	<formatter>
	<pattern-formatter pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/>
	</formatter>
	<file relative-to="jboss.server.log.dir" path="solr.log"/>
	<suffix value=".yyyy-MM-dd"/>
	<append value="true"/>
	</periodic-rotating-file-handler>

and a logger like

	<logger category="org.apache.solr">
	<level name="INFO"/>
	<handlers>
	<handler name="SOLRFILE"/>
	</handlers>
	</logger>

This will create file solr.log in the log directory. Also, it as the date changes, it will add suffix yyyy-MM-dd to the file. So file solr.log will always be for current date.

Thanks Prasad,

I have created the handler and logger as you said but I still do not get a solr.log file.

In the server.log I get the following warnings:

01:06:27,313 ERROR [stderr] (MSC service thread 1-1) log4j:WARN No appenders could be found for logger (org.apache.solr.core.SolrResourceLoader).

01:06:27,313 ERROR [stderr] (MSC service thread 1-1) log4j:WARN Please initialize the log4j system properly.

01:06:27,314 ERROR [stderr] (MSC service thread 1-1) log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

The jars I have in the WEB-INF/lib used for logging are:

log4j-1.2.16.jar

jcl-over-slf4j-1.6.1.jar

slf4j-api-1.6.1.jar

slf4j-log4j12-1.6.1.jar

I am not quite sure what I am missing.

Any suggestions?

So you are using log4j and not JBoss logging. You will have to create a log4j.xml file with the solr appenders/loggers in that file and package the log4j.xml in your application (.war/WEB-INF/classes folder)

As Jaikiran suggested, also have a look at this thread. http://community.jboss.org/thread/171288?tstart=0

I have added a log4j.properties in the solr.war/WEB-INF/classes directory and I got a solr.log.

The log4j.properties looks like this:

log4j.rootLogger=INFO, SOLR

log4j.appender.SOLR=org.apache.log4j.DailyRollingFileAppender

log4j.appender.SOLR.file=/opt/jboss-as-web-7.0.0.Final/standalone/log/solr.log

log4j.appender.SOLR.datePattern='.'yyyy-MM-dd

log4j.appender.SOLR.layout=org.apache.log4j.PatternLayout

log4j.appender.SOLR.layout.conversionPattern=%d %p [%c{3}] - [%t] - %X{ip}: %m%n

Thanks everyone.
