Monitoring vs Observability: Which Catches Unknown Failures First
Monitoring and observability get treated as synonyms in a lot of job postings and vendor slide decks. They aren’t. The difference isn’t a matter of tool sophistication as it’s a difference in what questions you’re even capable of asking when something goes wrong.
What is the difference between monitoring and observability?
Monitoring watches for failure conditions you’ve already anticipated. You define a metric, set a threshold, and get paged when the threshold is crossed. Observability is about your system’s ability to answer questions you didn’t know you’d need to ask — it requires high-cardinality, explorable telemetry that you can slice after the fact, without shipping new instrumentation.
Why doesn’t monitoring catch unknown failures?
Monitoring is often built on pre-aggregation: you pick your metrics in advance, and aggregation can obscure the outlier. A performance spike that affects only a specific tenant on a specific shard can disappear into a rolled-up average....
