Editor's Notes
- #5 They’re called data-scientists but these are analysts, SRE’s, DevOps and others
- #7 ASK: Who here believes that self-driving cars will be successful? This book was released exactly 50 years ago. Indeed, science fiction sometimes takes too long to become reality Seriously – let’s get skepticism out of the way – I’m going to be talking about a working concept. It’s not the car, or the street, or the stoplight. It’s the AI. AI is mature, it’s ready
- #8 Humans are better at top-down, or open-ended questions, such as “where should I open my next branch” Machines are superior in rigorous and exhausting tasks, such as “keep track on our sales in every state, sliced by affiliates, browsers; let me know if something happens”? Can we split responsibility?
- #11 Analysis is comprised of processing, analyzing, understanding, then acting. Loom Ops does the processing, analyzing, and – to some-extent – the understanding. We must have automated processing if we want to: Track much more Ingest many sources …
- #12 Loom covers the generic and common contexts, and will be able to inter-connect them with proprietary contexts
- #13 The single log line will automatically be processed and translated to 8 different metrics! This is without going into sequence analysis Can you see how hard it is to extract value from machine data?
- #16 We suppress “always-broken” alerts. The Machine-Learning based prioritization and filtering is self adjusting so that the incidents rate fits the size of the team
- #17 Detection is very hard and usually ends with a vague lead – such as user complaints, high CPU You then go to the logs (single source of truth) but there’s all this noise. You find many unusual things in different log streams. This is RCA – the process of understanding that the kids are fighting, not because Silvia pushed John and he pushed back, but because they’re hungry
- #18 Can you see how hard it is to extract value from machine data?
- #21 The ops guy gets an alert – high-cpu on Authentication server. He starts searching the logs for errors, and after some serious amount of work, he narrows it down to this log line. Can you tell the difference in the meaning of the two scenarios?
- #23 When things go wrong, it’s hard to tell the chain of causality
- #26 We have less alerts because we suppress “always-broken” alerts, and with the help of ML-based prioritization and filtering. This reaches a much better result when compared to a human-built rule engine Can you see how hard it is to extract value from machine data? Then, it’s the quality of the incident, translating to MTTR. Fuzzy matching is crucial because no one uses ticketing systems. You need to get it in “push”. And you need to be able to provide simple, fast feedback
- #27 BTW, Anomaly detection makes it possible for us to suppress “always-broken” alerts. We also used Machine-Learning based prioritization and filtering – we adjust the incidents rate to the size of the team. Fuzzy matching is crucial because no one uses ticketing systems. You need to get it in “push”. And you need to be able to provide simple, fast feedback
