Svalogger

Svalogger is a software logging framework designed to collect, format, store, and export log messages from applications and devices. It emphasizes low overhead, configurability, and support for structured data, making it suitable for embedded systems, microservices, and IoT deployments. The term may refer to several independent implementations rather than a single canonical project.

Core concepts in svalogger include a lightweight core that emits events with severity levels and timestamps, and formatters that produce structured representations such as JSON or key-value formats. Transports or backends send log data to destinations such as local files, syslog servers, remote endpoints over TLS, or cloud logging services. Features commonly found in svalogger implementations include log rotation, retention policies, sampling to reduce volume, and support for both synchronous and asynchronous delivery.

Configuration is typically performed through code or declarative configuration files, enabling per-module log levels, tags, and correlation identifiers to facilitate end-to-end tracing in distributed systems. Architectural variants may provide pluggable backends, queues, and buffer management to handle bursty log traffic. Security considerations often include TLS encryption, authentication, and access controls for log destinations.

Typical use cases encompass production monitoring and troubleshooting, auditing and compliance, debugging in development, and telemetry collection for distributed infrastructures. History and governance of svalogger are diverse, as the term describes multiple implementations rather than a single official project; documentation, APIs, and behaviors can vary between instances.
