PAGE 5 NetBrain: Automating Problem Diagnosis Consider network automation as a journey that can be broken down into highly achievable steps over time. Referring to the chart, you can see that as your maturity progresses from one level to the next, you derive greater value and operational scale Mean-Time-To-Repair (MTTR) can be used as a proxy for maturity as it forms the baseline case for a completely manual operational plan In the chart, we see that as the use of automation increases, MTTR decreases The net difference between the two curves is the true and very tangible value of migrating to an automation-centric network operations approach You can see from the chart why MTTR is used as a proxy to understand the value of automation Most organizations can articulate their average MTTR These organizations have manual processes, so their MTTR can be used as the baseline in their automation journey As organizations become more mature in their automation, it is quite easy to determine the tangible savings being realized through automation In simpler terms, the four hours that you typically spend manually executing a service ticket with CLI, may be reduced to two hours through automation, a savings of 50% And with large organizations reporting 5,000 or more service tickets per month, this yields a monthly aggregate savings of about 10,000 hours (or approximately 60 operators), which at prevailing engineer hourly rates can be estimated at almost $1 million per month! LEVEL 0 MANUAL Manual troubleshooting via Command Line Interface (CLI) Must understand every detail of every device LEVEL 1 INTERACTIVE Engineer uses automation to increase data collection and analysis efficiency Leveraging Runbooks and Dynamic Maps LEVEL 2 COLLABORATIVE Engineers are writing automations for teammates to use and share their knowledge in executable format Leveraging Guidebooks LEVEL 3 TRIGGERED Event or incident triggered execution of diagnosis for all known problems begins instantly Output results to NetBrain incident portal LEVEL 4 PREVENTATIVE Proactive validation of network intents running continuously in the background Enforce design rules, security policies and application best practices BASELINE MTTR MEAN TIME TO REPAIR AUTOMATION MATURITY NetBrain PDAs Advantage • Scale Network Operations • Reduce MTTR, Leverage SMEs • Prevent Problems From Happening Again • Reduce Human Dependency & Errors
