RE: DatePatterns in RollingFileAppender

Wed, 17 Aug 2005 22:12:08 -0700

hi
 
Thanks for a quick reply.  I am facing the following problems regarding the use of DatePattern in RollingFileAppender:
 
1. I used DatePattern as "yyyy-MM" to Roll at the beginning of each month like below:
 
           RollingFileAppender appender = new RollingFileAppender();
            SimpleLayout layOut = new SimpleLayout();
            appender.Name = "CustomRoller";
            appender.File = <FullPathTo File>
            appender.AppendToFile = true;          
            appender.RollingStyle = RollingFileAppender.RollingMode.Date;
            appender.DatePattern = "yyyy-MM";
            appender.Layout = layOut;
            appender.ActivateOptions();   
 
I found that RollingFileAppender does not identify this pattern. RollingfileAppender.ComputeCheckPeriod() returns "RollPoint.TopOfTrouble" when I passed the above DatePattern.
 
Can you please let me know what DatePattern I should use to roll the log each month(RollPoint.TopOfMonth)
 
2. I am unable to identify the DatePattern that I should use to roll the log each week(RollPoint.TopOfWeek). Please let me know by example the DatePattern I should use for rolling the log each week. If "RollPoint.TopOfWeek" option is used then at which day of the week the rolling will take place . Is it the first day of the week, which can be different depending on the locale or the last day of the week or some defined day only??
 
Thanks
Shaily

The RollingFileAppender uses DateTime.ToString(pattern) to convert the
date to a string.
See http://msdn2.microsoft.com/library/8kb3ddd4(en-us,vs.80).aspx for
details of the pattern specifiers.

yyyy-MM

not possible, no date pattern for day of week


> 3.  Rollover at midnight each day

yyyy-MM-dd


> 4.  Rollover at midnight and midday of each day

yyyy-MM-ddt


> 5.  Rollover at the top of every hour

yyyy-MM-dd-HH


> 6.  Rollover at the beginning of every minute

yyyy-MM-dd-HH-mm
