Welcome to the Open Source Alerting Guide! This document provides an overview of the alerting capabilities available in our open source projects. We aim to help you understand how to set up and configure alerts for your applications and systems.

Overview

Alerting is a critical component of any monitoring system. It allows you to be notified of important events and issues in real-time, enabling you to take action promptly. Our open source projects offer robust alerting features that can be integrated into your monitoring infrastructure.

Key Features

  • Real-time Alerts: Receive notifications immediately when events occur.
  • Customizable Alerts: Configure alerts based on specific conditions and thresholds.
  • Integration with Monitoring Tools: Seamlessly integrate with popular monitoring tools like Prometheus, Grafana, and more.
  • Alerting Policies: Define policies to manage and route alerts based on your requirements.

Getting Started

To get started with alerting, follow these steps:

  1. Install a Monitoring Tool - Choose a monitoring tool that supports alerting.
  2. Configure Alerting Rules - Define your alerting rules based on your requirements.
  3. Set up Notification Channels - Configure how you want to receive alerts (e.g., email, SMS, Slack).

Configure Alerting Rules

Alerting rules define the conditions under which alerts will be triggered. Here's how you can configure alerting rules:

  • Define Metrics: Specify the metrics you want to monitor.
  • Set Thresholds: Define thresholds for the metrics.
  • Configure Conditions: Set conditions that must be met for an alert to be triggered.

Example Rule

- name: High CPU Usage
  expr: cpu_usage > 90
  for: 1m
  labels:
    severity: critical
  annotations:
    summary: "High CPU usage detected on {{ $labels.instance }}"

Set up Notification Channels

Notification channels are used to deliver alerts to your preferred communication channels. Here are some popular notification channels:

  • Email: Send alerts to your email address.
  • SMS: Receive alerts via SMS on your mobile phone.
  • Slack: Post alerts directly to your Slack channel.

Example Configuration

email:
  to: admin@example.com
sms:
  to: +1234567890
slack:
  webhook_url: https://hooks.slack.com/services/your/webhook/url
