Hi all (hi Nick!)
I've just contributed to a discussion on Linkedin re Splunk and SCADA and thought I'd poke my head in here too.
We (Remora - remora.com.au) are actively participating in SCADA data monitoring with Splunk. Our clients are utility companies (currently only utilities in Australia). We have a number of tried-and-true methods for interfacing DIRECTLY with SCADA devices (to PLCs and also straight to RTUs) using a number of old-school protocols, then passing that data as name-value pairs to Splunk. We then do some beautiful things with the data, far beyond what traditional "process historians" etc do with the data. We can achieve better results in predictive failure analysis (PFA) than any other system we've seen (and better than any of our clients have seen) in a MUCH shorter amount of time (and data). I call it "the other side of the mirror" (Alice In Wonderland style) for Splunk - there may be a lot we can do with computer-generated data, but we enjoy analysis of machine-generated data - REAL machines. We have a case study of our biggest client coming out via Splunk in the next few weeks, watch out for it!
