This link shows the latest preferred version of the log4j properties =
file for
all applications.
=20
http://epic52.dep.state.fl.us/arm-pars/log4j.properties
=20
The changes from the previous version will greatly enhance our ability =
to
derive useful information from the logs. In addition, the use of =
appenders
to send log output to stdout and the console is specifically =
discouraged.
Output that previously was sent to stdout and to the console was being =
picked
up in the opmn log for each container. Since we have individual =
application
logs this was redundant and not an appropriate use of server resources. =
My
thanks to Charles Li for helping me fix this problem.
=20
I encourage all projects to utilize the link above to implement their =
own
log4j.properties file. Only one change, the log file name, is required. =
And
of course all project leads know that the use of system.out.println in =
code
is specifically discouraged in favor of real logging statements. =
Liberal use
of logging greatly enhances our ability to see what is happening in the =
code.
Code without log statements is difficult to follow and troubleshoot.
=20
As a result of the ImsMes project being in Production service we will =
have
additional requirements for monitoring of the application for the =
initial two
weeks after going to Production. I will add this to our policies page =
and
direct your attention to it in the near future. For now, we are going =
to
adjust the logging level down so that only warnings, errors and fatal =
log
messages are logged. debug and info are not of interest in Production.
