Key Questions Answered
How does Mantis improve operational insights for Netflix?
Mantis improves operational insights by allowing engineers to quickly identify issues, trigger alerts, and apply remediations to minimize downtime. It processes metrics in seconds, significantly reducing the Mean-Time-To-Detect from tens of minutes to mere seconds, which is critical for maintaining service quality.
What are the guiding principles behind building Mantis?
The guiding principles include access to raw events, real-time event processing, the ability to ask new questions without additional instrumentation, and cost-effectiveness. These principles ensure that Mantis can provide valuable insights while minimizing operational costs.
What applications have been built on the Mantis platform?
Several applications have been built on Mantis, including real-time monitoring of streaming health, contextual alerting for anomalies, and chaos experimentation monitoring. These applications leverage Mantis's capabilities to enhance operational insights and improve service reliability.
Key Statistics & Figures
Mean-Time-To-Detect
Reduced from tens of minutes to seconds
This improvement is vital for minimizing downtime and enhancing service quality.
Impact of outages
A five-minute outage today is equivalent to a two-hour outage at the time of the last Mantis blog post
This highlights the growing importance of rapid insights as Netflix's member base expands.

Key Actionable Insights
1Leverage Mantis to publish all operational data for future insights.By using Mantis's on-demand model, you can publish 100% of your operational data without incurring costs until the data is subscribed to. This allows for greater flexibility in answering new questions as they arise.
2Utilize real-time processing to enhance service reliability.Mantis processes events in real-time, which is crucial for large-scale systems where traditional batch processing can lead to delays. Implementing this can significantly reduce downtime and improve user experience.
Common Pitfalls
1
Failing to publish raw events can lead to loss of valuable data insights.
If applications transform events prematurely, critical context may be lost, making it difficult to derive insights when new questions arise.
