Hello,
I have the following XML configuration file for my webapp (under Tomcat 9).
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="info">
<Properties>
<Property
name="log-path">C:\Projects\TomcatDevServer\logs\</Property>
<Property name="now">${sys:startup}</Property>
</Properties>
<Appenders>
<RollingFile name="FILES" fileName="${log-path}/capsico.log"
filePattern="${log-path}/capsico.${now}.%i.log.gz">
<PatternLayout>
<pattern>%d{MMdd.HHmmss.SSS}#%-3t %level{length=1}
%15.15c{1}| %m%ex{20}%n</pattern>
</PatternLayout>
<Policies>
<SizeBasedTriggeringPolicy size="100 MB" />
</Policies>
<DefaultRolloverStrategy max="99999"
compressionLevel="9"/>
</RollingFile>
<Async name="ASYNC">
<AppenderRef ref="FILES" />
</Async>
</Appenders>
<Loggers>
<Root level="debug">
<AppenderRef ref="ASYNC" />
</Root>
</Loggers>
</Configuration>
I have done one thing that I haven't seen in any example, which is that all
the logs are tagged with the timestamp of when the system started (using
${sys:startup}), rather than using an inline timestamp format. This allows
me to group all log files per "server startup". This works well.
Now, I would like to do the same thing for the initial/starting file, and I
have tried fileName="${log-path}/capsico.${sys:startup}.log" but with no
success. I have also tried:
- fileName="${log-path}/capsico.$${sys:startup}.log"
- fileName="${log-path}/capsico.${now}.log"
- fileName="${log-path}/capsico.$S{now}.log"
I find this easier to manage in development or when troubleshooting
deployment issues where the server may be re-started multiple times: instead
of having a single "start" file with all the logging appended across
multiple server restart, I would like to always get a new clean file
everytime.
Can this be done? I am sure there is a way by writing some Java code and
all, but trying to figure out a config-level way first if available.
Thank you,
