Logs MLServe telemetry events, with no dependencies beyond Logger.

The fastest way to see what MLServe is doing. Attach it in application.ex while developing, or in production at :info to record model loads and unloads without wiring up a metrics backend:

MLServe.Telemetry.Logger.attach(level: :info, events: [:model])

For real observability use MLServe.Telemetry.Metrics with LiveDashboard or a StatsD/Prometheus reporter — logging every prediction in production is a way to spend your I/O budget on strings.

Options

• :level — log level, defaulting to :debug
• :events — which groups to log: :prediction, :model, :cache, :batch. Defaults to [:prediction, :model]; cache and batch events are high-volume.
