Staying consistent with semantic conventions
One of the most important questions we’re yet to discuss is what information to add to telemetry signals to make them useful – this is where OpenTelemetry semantic conventions come into play.
Semantic conventions describe what information to collect for specific technologies, such as HTTP or gRPC calls, database operations, messaging scenarios, serverless environments, runtime metrics, resource attributes, and so on.
