Quick Start

1. Minimal Configuration

Begin with minimal setup by importing the ReporterModule in your application's AppModule:

import { Module } from "@nestjs/common";
import { ReporterModule } from 'nestjs-metrics-reporter';

@Module({
    imports: [
        ReporterModule.forRoot({
            defaultMetricsEnabled: true,
            defaultLabels: {
                app: 'my-app',
                environment: 'production',
            },
            // Add optional configurations here
        }),
    ],
})
export class AppModule {
}

2. Reporting Metrics Anywhere

Once initialized, you can report metrics from any location throughout your application:

import { Injectable } from '@nestjs/common';
import { ReporterService } from 'nestjs-metrics-reporter';

@Injectable()
export class UserService {
    async createUser() {
        ReporterService.counter('users_created_total', {
            source: 'api',
            user_type: 'standard'
        });
        
        ReporterService.gauge('active_users', 42, {
            region: 'us-east-1'
        });
        
        await ReporterService.pushMetrics('user_service_job');
    }
}
