imfile in rsyslog in AIX servers

Question

AIX server's rsyslog (imfile module) is not forwarding custom application logs from a specific folder that has multiple log files generated each and every day. The log file's name pattern differs. I need help forwarding logs from those files and the files that will be generated in future. As of now in the configuration, i have given the wildcard (in $InputFileName) to read the files as ".log." as per the file name's pattern.

The file names are as follows:

abcd0000.log.190610
sdef0001.log.190611
asdfghjklas0000.log.190612
qwerty0004.log.190613

The imfile module configuration part is as follows:

$ModLoad imfile
$InputFileName /usr/bada/custom/application/*.log.*
$InputFileTag application1:
$InputFileSeverity info
$InputFileFacility local6
$InputFileMonitor

The version of rsyslog is:

rsyslogd 8.4.2, compiled with:
FEATURE_REGEXP:                          yes
GSSAPI kerberos 5 support:               No
