---------------------------------------------
sharing few more finding from the testing done yesterday(25th-07-2016), its
strange to see polymorphic behavior from CronTriggeringPolicy(CTP) with respect
to environment.

Simple Java code snippet used in testing:
-------------------------------------------------------------------------------------------------------------------------------------------------------
Logger dotLog = LogManager.getLogger("dotLog");
Logger dotCsv = LogManager.getLogger("dotCsv");
try{
for(int i=1;i>0;i++){
if(i<5){
dotLog.trace("dotLog trace message");
dotLog.debug("dotLog debug message");
dotLog.info("dotLog info message");
dotLog.error("dotLog error message");
dotCsv.trace("dotCsv trace message");
dotCsv.debug("dotCsv debug message");
dotCsv.info("dotCsv info message");
dotCsv.error("dotCsv error message");
System.out.println(i + " I'm going into sleep for a second " +
(i%5 == 0));
}
Thread.sleep(1000);
}
}catch(Exception e){
e.printStackTrace();
}

I executed above code snipped in a main method just before midnight of
25th-July-2016 in Windows7 OS machine,
1. app-2016-07-26_00-00-00-055.log
2. app-2016-07-26_00-00-00-056.csv
The similar code executed in one of the linux box, resulted below rolled-over
files.
1. app-2016-07-25_00-00-00-055.log
2. app-2016-07-26_00-00-00-056.csv
Try to catch, in linux machine .log extension file rolled-over at midnight with
previous day date in the file name, but .csv extension file rolled-over with
new day date in the file name.
Kindly share your thoughts, if you feel this is helpful.
Thank you.

> Hi.
> I tried CrontriggeringPolicy(added 2.5) for save daily log files at midnight.
> My goal is, for example.
> if today is 2015/01/01, "http.log" <- active file.
> and when midnight, "http.log" will be renamed "http_20150101.log", and create
> new "http.log".
> But my problem is when midnight, "http.log" renamed "http_20150102.log"...
> I want to make that file's name "http_20150101.log" because that file has
> 2015/01/01's log,
> Here's my configure xml.
> {code:xml}
> <Routing name="routing_file">
> <Routes pattern="pattern1">
> <Route key="http">
> <RollingFile name="rolling_http" filename="${path}/http.log"
> filepattern="${path}/http_%d{yyyyMMdd}.log">
> <PatternLayout pattern="http"/>
> <CronTriggeringPolicy schedule="0 0 0 * * ?"/>
> </RollingFile>
> </Route>
> </Routes>
> </Routing>
> {code}
> Please help me.
> Thanks for your help, I'm very appreciated it :D
