What are MTTR and MTTI and why do they matter?
What is MTTR? Mean Time to Resolve (MTTR) is the average time between the start and resolution of an incident. But first you have to identify the problem.
That’s why Mean Time to Identify (MTTI) is also an important key performance indicator (KPI).
As DevOps teams release more often and automate more, performance and availability problems have increased. The result is Ops is spending more time troubleshooting and development is drawn into production troubleshooting. Reducing MTTR and MTTI is more crucial than ever.
How to Improve DevOps MTTR
By monitoring deployments in real time, you can drastically improve MTTI from days to minutes. Sumo Logic delivers a comprehensive strategy for monitoring application and system events, stats, network traffic and logs all in real time. So you can be proactive in identifying unexpected conditions and undesired behaviors.
Once you’ve identified an issue, Sumo Logic provides tools to help you to quickly troubleshoot issues, perform root-cause analysis and dramatically decrease MTTR.
For example, tools like Live Tail let you tail log files and apply pattern searches to bring up near real-time metrics within seconds. This can significantly lower the time developers spend troubleshooting issues in production and ultimately reduce MTTR.
