I understand PatternDB is a syslog-ng pluginand its dynamic library can be found in as libdbparser.so. I went through the following tests in ' https://github.com/balabit/syslog-ng/blob/master/modules/dbparser/patterndb.... ' I want to create two independent pattern_db instances having two different ruleset. My queries: 1) How can I create two independent instances of patternDB having two different ruleset ? 2)How can I get the handle of these two independent PatternDB instances ? Can someone please help me on this ? Thanks
