java - log4j how I can get FileAppender's name with log4j..getRootLogger() -


i use log4j.getrootlogger().getappender("ficwarn") in java code, can't path of fileappender.

how can name of file messages written ?

it file defined in log4j.propertiers or log4j.xml.

better log this:

private static final logger = loggerfactory.getlogger(classname.class); // or specific channels     private static final logger = loggerfactory.getlogger("ficwarn");

now define appender in log4j

<?xml version="1.0" encoding="utf-8" ?> <!doctype log4j:configuration system "log4j.dtd">  <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">   <appender name="console" class="org.apache.log4j.consoleappender">      <param name="target" value="system.out"/>      <layout class="org.apache.log4j.patternlayout">        <param name="conversionpattern" value="%-5p %c{1} - %m%n"/>      </layout>    </appender>     <appender name="ficwarn" class="org.apache.log4j.rollingfileappender">      <param name="file" value="ficwarn.log"/>     <param name="maxfilesize" value="100kb"/>     <!-- keep 1 backup file -->     <param name="maxbackupindex" value="1"/>     <layout class="org.apache.log4j.patternlayout">        <param name="conversionpattern" value="%p %t %c - %m%n"/>      </layout>    </appender>     <logger name="ficwarn">     <level value="info"/>      <appender-ref ref="ficwarn" />    </logger>    <root>      <priority value ="debug" />      <appender-ref ref="console" />    </root>  </log4j:configuration>

now messages go either console (classname) or ficwarn.log (string = "ficwarn").

i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
