Which alerts should I configure for Edge and CDN with Grafana?

        {
            "alert": {
                "title": "High Latency Alert",
                "condition": "avg(latency) > 200",
                "message": "Average latency is above 200ms for the last 5 minutes",
                "threshold": 200
            },
            "alert": {
                "title": "Error Rate Alert",
                "condition": "sum(errors) > 10",
                "message": "Error rate exceeds 10 requests in the last 5 minutes",
                "threshold": 10
            },
            "alert": {
                "title": "Uptime Alert",
                "condition": "uptime < 99.9",
                "message": "Uptime has dropped below 99.9% in the last hour",
                "threshold": 99.9
            }
        }
