Masterly.BusinessRules.Diagnostics

Structured ILogger logging, OpenTelemetry tracing spans and Meter metrics for business-rule evaluation. Use it when you want rule outcomes in your logs and telemetry without writing an observer.

This is a companion package of Masterly.BusinessRules, a composable business-rule engine for .NET.

NuGet

Install

dotnet add package Masterly.BusinessRules.Diagnostics
  • Target framework: netstandard2.1 (.NET Core 3.0+, .NET 5+)
  • Dependencies: Masterly.BusinessRules, Microsoft.Extensions.Logging.Abstractions 10.0.14, System.Diagnostics.DiagnosticSource 10.0.14

Example

using System.Collections.Generic;
using Masterly.BusinessRules;
using Masterly.BusinessRules.Diagnostics;
using Microsoft.Extensions.Logging;

public sealed class CheckoutValidator
{
    private readonly ILogger<CheckoutValidator> _logger;

    public CheckoutValidator(ILogger<CheckoutValidator> logger)
    {
        _logger = logger;
    }

    public RuleEvaluationResult Validate(IEnumerable<IBusinessRule> rules, BusinessRuleContext context)
    {
        // One structured log line per broken or faulted rule: RuleCode, RuleName, Category, Severity, Outcome, ElapsedMs.
        RuleEvaluationOptions options = new RuleEvaluationOptions
        {
            Observer = new LoggingRuleExecutionObserver(_logger)
        };

        return BusinessRuleChecker.EvaluateAll(rules, context, options);
    }
}

For async batches use LoggingAsyncRuleExecutionObserver. For tracing and metrics, attach TracingRuleExecutionObserver (or TracingAsyncRuleExecutionObserver) and subscribe to the ActivitySource named BusinessRulesActivitySource.Name and the Meter named BusinessRulesMetrics.MeterName; no OpenTelemetry extension package is needed.

Documentation

Log levels and options, span and metric names, and the .Traced() decorator are covered in the full documentation: https://github.com/a7mdfre7at/Masterly.BusinessRules#readme
