===== Azure Monitor Baseline Alerts (AMBA) Discussion ===== ==== Introduction ==== AMBA provides predefined alert configurations for Azure resources, helping to monitor health, performance, and security by setting thresholds on critical metrics. ==== Coexistence with Policies ==== AMBA and Azure Policies are complementary. While policies enforce governance and compliance, AMBA ensures operational health by setting up alerts. ==== Enforcing AMBA with Policies ==== You can enforce AMBA baselines through Azure Policy to ensure alerts are consistently applied across resources for compliance and operational governance. ==== AMBA’s Focus ==== AMBA is primarily about enabling different alerts for resource monitoring. ==== Source of Alerts ==== The alerts in AMBA are based on metrics and diagnostic data collected from Azure Monitor. ==== Networking Coverage ==== AMBA covers: * Virtual Networks * Application Gateways * Load Balancers * VPN Gateways * Network Interfaces Monitoring traffic patterns, availability, latency, and connection health. ==== PaaS Services Coverage ==== AMBA covers PaaS services like: * Azure App Service * Azure SQL Database * Azure Cosmos DB * Azure Kubernetes Service (AKS) * Azure Storage ==== Azure Virtual WAN Coverage ==== For Azure Virtual WAN, AMBA monitors: * VPN Gateway Connection Health * ExpressRoute Circuit availability * Latency and hub health ==== Example Alerts ==== * **VPN Gateway Connection Health Alert**: Detects lost or unstable VPN connections. * **ExpressRoute Circuit Down Alert**: Tracks circuit outages or degradation. * **Latency in Hub Connections**: Monitors high latency across WAN hubs. ==== How to Navigate and Find Alerts in Azure ==== To best navigate and find alerts in Azure: 1. **Azure Portal**: Go to the Azure Monitor service. 2. **Alerts**: Select "Alerts" under the Monitor section to see all alert rules. 3. **Filter and Search**: Use filters like resource type, severity, or signal type to find specific alerts. 4. **Create Alerts**: Define new alert conditions based on metrics, logs, or activity. 5. **Action Groups**: Configure notifications or automated actions linked to alerts.
