The Na­tional Ig­ni­tion Fa­cil­ity (NIF) is the world's largest and most en­er­getic laser ex­per­i­men­tal fa­cil­ity with 192 beams ca­pa­ble of de­liv­er­ing 1.8 mega­joules and 500-ter­awatts of ul­tra­vi­o­let light to a tar­get. To aid in NIF con­trol sys­tem trou­bleshoot­ing, the com­mer­cial prod­uct Splunk was in­tro­duced to col­late and view sys­tem log files col­lected from 2,600 processes run­ning on 1,800 servers, front-end proces­sors, and em­bed­ded con­trollers. We have since ex­tended Splunk's ac­cess into cur­rent and his­tor­i­cal con­trol sys­tem con­fig­u­ra­tion data, as well as ex­per­i­ment setup and re­sults. Lever­ag­ing Splunk's built-in data vi­su­al­iza­tion and an­a­lyt­i­cal fea­tures, we have built cus­tom tools to gain in­sight into the op­er­a­tion of the con­trol sys­tem and to in­crease its re­li­a­bil­ity and in­tegrity. Use cases in­clude pre­dic­tive an­a­lyt­ics for alert­ing on pend­ing fail­ures, an­a­lyz­ing shot op­er­a­tions crit­i­cal path to im­prove op­er­a­tional ef­fi­ciency, per­for­mance mon­i­tor­ing, pro­ject man­age­ment, and in an­a­lyz­ing and mon­i­tor­ing sys­tem avail­abil­ity. This talk will cover the var­i­ous ways we've lever­aged Splunk to im­prove and main­tain NIF's in­te­grated con­trol sys­tem.
