Hi Ralph,
thanks for taking some time.
Basically I want a log which rotates at midnight and is limited in file
size. So I'd expect that these files are generated:
/2020_04_27/msg-2020_04_27-12_17_00.log (application started)
/2020_04_27/msg-2020_04_27-18_13_30.log (log file exceed 250MB)
/2020_04_28/msg-2020_04_28-00_00_00.log (next day)
I guess the suggested pattern isn't the entire solution since with
* TimeBasedTriggeringPolicy) Is now invalid due the missing %d
* CronTriggeringPolicy) Just creates one big log file
`msg-2020_04_27-00_00_00.log` ignoring the file limitations
Thanks

The %d pattern only applies to time based rollovers. If you want the
time in a size based rollover pattern then use the date lookup
filePattern=/tmp/msg-$${date:yyyy_MM_dd}/nps-message-$${date:yyyy_MM_dd_HH_mm_ss}.log

I guess I've been glad to early.
```
appender.msglog.type = RollingFile
appender.msglog.name = localmsglog
appender.msglog.filePattern =
/tmp/msg-%d{yyyy_MM_dd}/nps-message-%d{yyyy_MM_dd_HH_mm_ss}.log
appender.msglog.layout.type = log4j1xmllayout
appender.msglog.policies.type = Policies
appender.msglog.policies.size.type = SizeBasedTriggeringPolicy
appender.msglog.policies.size.size = 250MB
```
Is rolling the file as expected.
I now tried to configure a nightly roll.
by adding `appender.msglog.policies.cron.type =
CronTriggeringPolicy`. I also tried
`appender.msglog.policies.time.type = TimeBasedTriggeringPolicy`. Both
results into a single log file `msg-2020_04_27_00_00_00-0.log` and
size based logging stops working.
Any ideas? Maybe I misunderstand some basic concept?
Thanks in advance

Sorry for noise.

Hej!
Currently I try to configure log4j2 to:
* create a log in a folder with dates: e.h.
2020_04_27/messages.20200427_13_39_01.log
* limit the log size to 250MB
(* use a custom layout)
(* rollover every day)
But I'm already stuck with the first two bullets
```
appender.msglog.type = RollingFile
appender.msglog.name = localmsglog
appender.msglog.filePattern =
/tmp/msg-${date:yyyy_MM_dd}/nps-message-${date:yyyy_MM_dd_HH_mm_ss}.log
appender.msglog.layout.type = log4j1xmllayout
appender.msglog.policies.type = Policies
appender.msglog.policies.size.type = SizeBasedTriggeringPolicy
appender.msglog.policies.size.size = 250MB
appender.msglog.strategy.type = DirectWriteRolloverStrategy
```
Basically the log is created in the correct folder and with the
correct name. But the file is not rolled after 250MB .
I digged a little bit into the source and recognized that the
`DirectWriteRolloverStrategy` does not get the pattern, but the
current log file name, so it does not contain the `filePattern` at
all.
Now I'm unsure if this is a bug or a configuration issue.
Thanks in advance
