Oh yes, apologies... I did some edits to simplify my config file and accidentally changed $ to %. It is correct in the file. I tried ${date:yyyy-MM-dd} and it works. I'll read up on what "date:" is.

Second, all that is going to do is replace ${now} in the file name with %d{yyyy-MM-dd} which will then be resolved when the file is created. I would suggest defining now as ${date:yyyy-MM-dd} Ralph > On Feb 24, 2018, at 12:13 PM, Laurent Hasson <l...@capsicohealth.com> wrote: > > Hello, > > I'd like to parametrize my log file names with the start date of the process. > This makes it easier for us to see after the facts in the logs if a server > was restarted etc... > > The approach I took was the following: > <Properties> > <Property > name="log-path">C:\CAPSICO\_Stand_Alone_Runtime_\logs\</Property> > <Property name="now">%d{yyyy-MM-dd}</Property> > </Properties> > <Appenders> > <RollingFile name="FILES" fileName="${log-path}/capsico.%{now}.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> </Appenders> > > My thinking is that ${now} would be resolved when the system starts, and then > I could use the value in the file names.
