Added: src/java/org/apache/log4j/jdbc JDBCReceiver.java
Log:
created a first pass at a jdbcreceiver for use with chainsaw...
the receiver only runs the sql query one time..subsequent runs would create
duplicate event entries in chainsaw
not all fields are supported...patternlayout doesn't support properties and
jdbcappender doesn't support exceptions.
example appender configuration:
<appender name="JDBC" class="org.apache.log4j.jdbc.JDBCAppender">
<param name="password" value="userpass"/>
<param name="user" value="username"/>
<param name="driver" value="org.gjt.mm.mysql.Driver"/>
<param name="sql" value='insert into logtable (logger, timestamp
, level, thread, message, ndc, mdc, class, method, file, line) values ("%c", "%d
", "%p", "%t", "%m", "%x", "%X", "%C", "%M", "%F", "%L")'/>
<param name="URL" value="jdbc:mysql://127.0.0.1/test"/>
</appender>
If fields weren't separated when they were added to the database, unused fields
still need to be defined (all columns in the list below need provided, even if you
don't have them in your database) - use AS statements to make the column names match
example receiver configuration:
<plugin name="JDBCReceiver" class="org.apache.log4j.jdbc.JDBCReceiver">
<param name="password" value=""/>
<param name="user" value="root"/>
<param name="driver" value="org.gjt.mm.mysql.Driver"/>
<param name="sql" value='select logger as LOGGER, timestamp as
TIMESTAMP, level as LEVEL, thread as THREAD, message as MESSAGE, ndc as NDC, mdc as
MDC, class as CLASS, method as METHOD, file as FILE, line as LINE from logtable'/>
<param name="URL" value="jdbc:mysql://127.0.0.1/test"/>
</plugin>
