The KoreLogic Expression Language Library (libklel) is a C library that provides a simple expression language that can be embedded in other programs. It does not implement a full programming language, but rather a simpler expression language called KL-EL that is designed to provide arithmetic and logic operations in situations where embedding a full programming language would be overkill. KL-EL can access functions and variables exported from the embedding program, and is statically and strongly typed, which helps ensure that expressions are valid before they are executed. The embedding API is easy to use, and the library itself is very small.

Splunk Hogs is a quick Perl script that was written to find what systems are sending too many events to Splunk and using up all the licenses. This is good for several reasons: developers will turn debugging on and use up all the licenses, which will help catch it early; INFO messages get turned on and useless events will be sent, filling up the licenses; issues will be detected that were being ignored by others. The advantage over Splunk's SaveSearch is that it outputs the raw data, so you can import it into Nagios or other tools. It collects raw data from Splunk that consists of the host, Splunk server, and the count of events that took place.
