Listen to Your Machines: DevOps Analytics for Better Feedback Loops

Andi Mann, Chief Technology AdvocateSplunk@andimann

‘Known good practices’ for collecting, correlating, and analyzing DevOps data

3

Effective DevOps Practices● Improve collaboration and sharing between dev and ops

● Build trust and accountability between teams

● Break down barriers and improve handoffs between silos

● Establish trust and transparency between Dev. and Ops.

● Streamline flow of code from idea to cash

● Creating feedback loops at every stage

● Focus on impact on business goals and customer experience

Some Real-World ‘Metrics That Matter’21

“Developers can focus on innovation and not on building monitoring tools.”

“Web Ops can measure performance of releases in pre-prod, prod and in QA.”

“Gather all data, and it starts looking like one big system, instead of a bazillion teeny ones that hate each other.”

“We measure customer sentiment on Google Play in real time and can correlate it with code

releases and app performance.”

Enable Improved DevOps Agility22

Key Customer Benefits

-Robert Gonsalves,Web Operations

“It’s like we were working without peripheral vision before and now we have it.”

• Increased success rate of deployments• Ability to detect issues before they affect broad

production• Monitoring deployment process several times per day

Deliver Better Code Quality23

Key Customer Benefits

-Principal Engineer,Apollo Group

“Developers are now able to look for errors and troubleshoot issues five to 10 times faster by having all their event data centralized in Splunk.”

• Provide full visibility into QA sanity and load testing before production

• Exceed SLA thresholds with full visibility and benchmark key infrastructure metrics and errors

• Easily troubleshoot if tests do not contain the expected results

Enable Data-Driven Continuous Delivery24

-Alison Perkins, Senior Systems Engineer

“Dump all the logs into Splunk, and it starts looking like one big system, instead of a bazillion teeny ones that hate each other.”

Key Customer Benefits • Quickly validate and troubleshoot code pushes to

production• Ensure that new code does not negatively impact

performance or user experience • Reduced one application’s error rate by 2 orders of

magnitude in a matter of weeks

Enable Closer Business-IT Alignment

Allows DevOps to ensure quality of releases & avoid negative impact on service performance.

Analyze which new website features are being adopted, and how, by end users.

Insight fed back into the development cycle to improve customer engagement.
