Contributions
Maple brings traces, logs and metrics into a shared interface. A trace records the steps of a request across services; logs provide event details, while metrics track quantities over time. Using the OpenTelemetry standard, applications can send this data without adopting a proprietary collection agent. Maple stores and queries it through ClickHouse, connects related views using shared filters and time ranges, and exposes telemetry to coding agents through an MCP server. It can run as a hosted service, a self-hosted stack or a local binary.[3]
