I like that it's easy to use, has all sorts or log formats built in (including json), is super customizable so you can make everything look exactly how u want - even when there are multiple instances running at once etc., very robust search functionality for both structured/unstructured data types as well an API support which makes integrating into other systems extremely efficient! It also supports python scripting making integration more streamlined if using any flavor oo language such us ROR / ruby OR Python3+ easily possible via either splunks REST api interface + PYTHON scripts too!! Haven't found anything i dislike about this software yet but would love some suggestions from others who have used them before? Also can be costly compared wtih competitors especially those without free trial periods. Monitoring logs & alerts quickly by searching through various sources including unix tools along side windows services events tracing system health reports monitoring network traffic flows ect.
