Routing Alerts in Monitoring

1. Introduction

Routing alerts is a critical aspect of monitoring systems that ensures the right information reaches the right team members at the right time. This lesson covers the various methods and best practices for effective alert routing.

2. Key Concepts

• **Alert**: A notification that something requires attention.
• **Routing**: The process of directing alerts to specific users or systems based on defined criteria.
• **Severity Levels**: Categorization of alerts based on their importance (e.g., critical, warning, info).

3. Routing Methods

There are several methods to route alerts effectively:

1. Static Routing: Alerts are sent to predefined users or groups.
2. Dynamic Routing: Alerts are routed based on real-time metrics or conditions.
3. Escalation Policies: If an alert is not acknowledged within a certain timeframe, it escalates to higher-level support.

Example: Static Routing

{
    "alert": {
        "name": "CPU Usage High",
        "severity": "critical",
        "routing": {
            "static": ["ops-team@example.com"]
        }
    }
}
            

Example: Dynamic Routing

{
    "alert": {
        "name": "Disk Space Low",
        "severity": "warning",
        "routing": {
            "dynamic": {
                "condition": "disk_space < 10GB",
                "users": ["dev-team@example.com", "ops-team@example.com"]
            }
        }
    }
}
            

4. Best Practices

• Define clear alert severity levels.
• Use tagging for alerts to simplify dynamic routing.
• Regularly review and update routing policies.
• Test alert routing to ensure reliability.
