Monitoring and Alerting
Monitoring and Alerting is a crucial aspect of Azure SQL monitoring. You can configure monitoring tools to send alerts and notifications when specific thresholds or conditions are met.
These alerts can be tailored with precision for specific conditions or predefined thresholds, empowering you to respond quickly to issues and anomalies. This proactive approach minimizes downtime and service disruptions.
Azure Monitor allows you to create alert rules that alert you when specific events occur or essential metrics exceed established limits. This enables swift responses to issues, ultimately reducing the risk of downtime and disturbances.
Azure PaaS Alerts/Notification provides a range of alert categories, including High DTU (CPU Computes), High Memory, and Low Database Space. These alerts can be triggered by specific criteria, such as System CPU average usage or Database data or Log file space.
Here are some specific alert categories and their corresponding rule descriptions:
Azure PaaS DB Storage Analysis also provides a range of features, including the ability to analyze storage/capacity usage and detect customized conditions that require attention.
Capacity and Performance
Capacity planning is crucial to prevent overprovisioning or under-provisioning, which can lead to performance problems or unnecessary costs. Azure database monitoring helps track resource utilization over time, ensuring you allocate the correct number of resources to your databases.
Azure SQL database purchase models offer various service tiers based on Database Transaction Units (DTU), making it essential to monitor DTU limits and costs. This will help you stay within your service tier's Azure SQL database size limit and allocate resources and budget more effectively.
Monitoring DTU limits and costs can also provide a comprehensive view of your SQL database environment during bottlenecks and slowdowns, helping you identify the root cause of performance issues. With an Azure SQL database monitoring tool, you can see what percentage of available DTU your Azure SQL Database is consuming during day-to-day operations.
Azure SQL Database exposes built-in metrics related to connections, resource utilization, and query performance within the Azure portal. You can configure alerts based on these metrics to receive notifications when specific conditions or thresholds are met.
To monitor your DTU consumption, utilization, and limits, you can use SolarWinds Database Performance Analyzer. This tool will help you stay within your service tier's Azure SQL database size limit and allocate resources and budget more effectively.
