we have production environment in red-hat. How to Capture all error message in Log file and send the Log file by email??
Do we need shell script or java scheduler or by any other way we can achieve .

Scanning the log file may be hit or miss, and relying on that is a poor design for notifying of errors.

For our enterprise portlets, we specifically implement appropriate alert processes on failures. When a failure occurs within our portlets, we invoke the code to send an alert. In our case we're sending SNMP traps to a SiteScope server, but it just as easily could send an email w/ the failure info.

Just use SMTPAppender

log4j.appender.mail=org.apache.log4j.net.SMTPAppender


But, as David replied, we usually use SNMP traps.
