For critical log messages, you can be notified by email when the event occurs, rather than waiting until you check the logs.

The mail log is configured as a standard JDK log handler with Resin's <log-handler> tag.

== resin.xml configuration ==

The resin.xml configuration for the logger adds a java.util.logging handler using Resin's <log-handler> tag, and sets the logger level with the <logger> tag.

In this case, we're having the MailLogHandler listen for logs under "mycom.foo" classes and at the warning level or higher. Mails are sent to caucho@localhost.

  <resin xmlns="http://caucho.com/ns/resin"
       xmlns:resin="urn:java:com.caucho.resin">
 
    <log-handler name="mycom.foo" level="warning">
       <resin:MailLogHandler>
         <to>caucho@localhost</to>
       </resin:MailLogHandler>
    </log-handler>
 
    <logger name="mycom.foo" level="info"/>
  
    <cluster id=""> 
      <resin:import path="${__DIR__}/app-default.xml"/>
 
      <server id="" port="6800">
         <http port="8080"/>
      </server>
 
      <host id="">
        <root-directory>/var/www/public-html</root-directory>
 
        <web-app id=""/>
      </host>
    </cluster>
 
  </resin>
