This page provides information on Azure SQL Database and Managed Instance performance issues detected through the [Intelligent Insights](sql-database-intelligent-insights.md) database performance diagnostics log. The diagnostic log telemetry can be streamed to [Azure Monitor logs](../azure-monitor/insights/azure-sql.md), [Azure Event Hubs](../azure-monitor/platform/resource-logs-stream-event-hubs.md), [Azure Storage](sql-database-metrics-diag-logging.md#stream-into-storage), or a third-party solution for custom DevOps alerting and reporting capabilities.
