Hello Supraja,

Here is what the documentation states:

Multiple %d specifiers

It is possible to specify multiple %d specifiers but only one of which
can be primary, i.e. used to infer the rollover period. All other tokens
must be marked as auxiliary by passing the 'aux' parameter (see examples

Multiple %d specifiers allow you to organize archive files in a folder
structure different than that of the roll-over period. For example, the
file name pattern shown below organizes log folders by year and month
but roll-over log files every day at midnight.

/var/log/%d{yyyy/MM, aux}/myapplication.%d{yyyy-MM-dd}.log


Notice that the secondary (aux) %d specifier given before the primary
specifier. The secondary specifier is used to create folders.

Have you tried that?
