ores.telemetry.core

ores.telemetry.core is the observability library for ORE Studio. It provides structured logging via Boost.Log with trace and span ID correlation (aligned with OpenTelemetry semantics), the messaging types the service exchanges, and domain types for log records and resource identity (host, service, version). All other components link against this library to emit structured, correlated logs, and the sink the host installs decides where a record goes: the database sink writes it through ores.telemetry.database.

• Log events emitted by other components via the Boost.Log sink interface.
• Configuration for the log level, the service identity and the record's source.

• Structured log_record objects handed to the sink the host installs.
• The message and payload types the six telemetry.v1.> subjects carry, generated from the three operation models.

• include/ores.telemetry.core/log/ — Boost.Log initialisation, the lifecycle manager and the sinks.
• include/ores.telemetry.core/generators/ — trace/span ID generators.
• include/ores.telemetry.core/domain/ — log_record, trace_id, span_id, resource.
• include/ores.telemetry.core/messaging/ — the generated protocol headers.
• include/ores.telemetry.core/exporting/ — logging configuration and options.

• Boost.Log — structured logging sink infrastructure.

What the shared profile cannot know, declared here rather than hand-edited into the generated build file. Each block is spliced into its generated file after the profile's baseline.

• ores.telemetry.service — NATS service that receives and persists log records.
• ores.telemetry.database — persistence layer for telemetry records.
• ores.telemetry Messaging Reference — NATS protocol for log forwarding.

The suites link what the profile cannot know about.
