Vostok.Logging is a set of libraries providing structured logging for .NET applications, much like Serilog, but tightly integrated into Vostok ecosystem.
Logging system should not be able to significantly impact application health or performance.
Guarantees section covers this topic in greater detail.
Configuration is done in code.
Configuring and composing loggers in code is preferable to clumsy XML files. See Configuration section for an in-depth discussion.
Extensibility is valued.
The libraries are designed in a way that encourages creating custom implementations of logs and decorators.
Performance is of essence.
Implementations go to great lengths to provide a throughput level sufficient for applications handling tens or even hundreds of thousands of requests per second.
Structured logging
Log events contain key-value properties which are later used for querying the log data or rendering it to text.
Reliable built-in log implementations
Console, file and Hercules logs comply to strict guarantees and offer solid performance.
Easy configuration
Most log implementations require just one line of code to set up (see Quickstart).
Customizable formatting
Output produced by text-based logs (console and file) can be customized with output templates.
Filtering of log events
There's built-in support for filtering by level, properties or arbitrary contents of log events.
Enrichment of log events with custom properties
Log events can be dynamically enriched with new properties either specified by user or provided from ambient context.
Integrations with other popular logging libraries
There are adapters available for Serilog, log4net and Microsoft.Extensions.Logging.
