All Metrics Are Wrong, Some Are Useful - OpenObservability Talks S1E6

The sixth of our OpenObservability Talks has Avishai Ish-Shalom, Developer Advocate at ScyllaDB.

We trust our metrics to show us the status of our system and where it misbehaves. But do our metrics show us what really happened? You'd be surprised how often it's not the case. 

On this episode we discussed the math behind metrics, some common misconceptions, what it take to have accurate metrics, and if there even is such a thing.

Avishai Ish-Shalom has served as Engineer in Residence in Aleph VC, engineering manager at Wix.com, co-founded Fewbytes and consulted many other companies on software operations, reliability, design and culture. Currently Avishai is a Developer Advocate for ScyllaDB, the open source NoSQL database.
