correct regex for whitelisting files

I have files that have names like this:
appflow-0017c569f354.syslog-dynamic-96
appflow-0017c569f354.syslog-dynamic-97
appflow-0017c569f354.syslog-dynamic-102
...

I tried the following regex:

appflow-+[0-9a-z]{12}+.syslog-dynamic-+[0-9]{1,6}

but splunk was not indexing any of the files. What is the correct regex?

I would suggest;

appflow-[a-z0-9]{12}\.syslog-dynamic-\d+

which is probably precise enough.

Hi,

Also an idea:

appflow-[^\.]+\.syslog-dynamic-\d+
