This hits home. We just lived through a 'migration' of sorts (launching a new Teams app) where the 'silent failure' wasn't the pipeline, but the observability layer itself.
Our dashboard reported a total flop: 1 visitor. Stakeholders were ready to pivot.
But we dug into the upstream logs (raw ingestion), and the reality was 121 unique visitors. The pipeline worked; the 'single pane of glass' lied.
If we hadn't validated the data at the source, we would have made strategic decisions based on a hallucination.
Lesson learned: In any migration or launch, don't trust the dashboard until you've verified the raw logs.
