API Logs and Metrics

Observe and fix API issues quickly with high-cardinality, high-dimension API logs and metrics. Traditional log search is too slow and unorganized for deep insights while single-value metrics need to be preplanned and unable to answer the arbitrary question required to root cause complex API issues.

Leverage Moesif's structured event-based data and wicked fast query engine to get real-time API observability of your APIs and issues whether you're building REST, GraphQL or decentralized APIs.
