enable a dynamic fileName (server.{date}.log )in RollingFile

Question:
How to enable dynamic fileName in RollingFileAppender

I have a requirement where i need to create a log file like
server.2024-04-30.log and it has some size based policies when roll over happens the existing file should be renamed to server.2024-04-30.1.log and when the day changes a new file need to be created like server,2024-05-01.log

server.2024-04-30.log
server.2024-04-30.1.log
server.2024-04-30.2.log

and when day changes it should be
server.2024-05-01.log

I have tried different approaches

Approach1:

       <RollingFile name="FILEC" fileName="${sys:pf.log.dir}/test.${date:yyyy-MM-dd}.log" 
                    filePattern="${sys:pf.log.dir}/test.%d{yyyy-MM-dd}.%i.log" 
   				 ignoreExceptions="false" append="false">
           <PatternLayout>
               <!-- Uncomment this if you want to use UTF-8 encoding instead
                   of system's default encoding.
               <charset>UTF-8</charset> -->
               <pattern>%d %X{trackingid} %-5p [%c] %replace{%m}{\n}{\\n}%n</pattern>
           </PatternLayout>
           <Policies>
   	<TimeBasedTriggeringPolicy />
               <SizeBasedTriggeringPolicy  size="100 KB" />
           </Policies>
           <DefaultRolloverStrategy max="12" />
       </RollingFile>

size based rolling is happening fine but when the day changes the fileName was the old date when i have restarted the application, rollover files have correct date as filePattern is working.

Approach2:

followed the discussion on https://issues.apache.org/jira/browse/LOG4J2-1185 and remove the fileName and tried it , log file itself is not getting created

        <RollingFile name="FILED"
                     filePattern="${sys:pf.log.dir}/application.%d{yyyy-MM-dd}.%i.log" 
					 ignoreExceptions="false" append="false">
            <PatternLayout>
                <!-- Uncomment this if you want to use UTF-8 encoding instead
                    of system's default encoding.
                <charset>UTF-8</charset> -->
                <pattern>%d %X{trackingid} %-5p [%c] %replace{%m}{\n}{\\n}%n</pattern>
            </PatternLayout>
            <Policies>
				<CronTriggeringPolicy schedule="0 0 * * * ?"/>
                <SizeBasedTriggeringPolicy
                        size="1 MB" />
            </Policies>
            <DefaultRolloverStrategy max="12" />
        </RollingFile>

Any help would be appreciated
