Hi Tejas,
The im_file supports wild cards, kindly review the configuration below.
<Input audFIles>
Module im_file
File "/u01/app/admin/admin/STG19/adump/*.aud"
</Input>
<Output tcp>
Module om_tcp
Host 192.168.1.1:514
</Output>
<Route messages_to_tcp>
Path audFiles=> tcp
</Route>
Kindly review the link for more information on this. I hope this helps.
