Options of regular expressions

This chapter lists regular expressions supported by syslog-ng OSE Open Source Edition (syslog-ng OSE) and their available supported type() and flags() options.

By default, syslog-ng OSE uses PCRE-style regular expressions. To use other expression types, add the type() option after the regular expression.

The syslog-ng OSE application supports the following regular expression type() options:

• Perl Compatible Regular Expressions (pcre)

• Literal string searches (string)

• Glob patterns without regular expression support (glob)
