Use Case: High CPU Caused by Too Many Short-Lived Connections

 

 

In this section, we will walk you through a real-world use case where the Troubleshooting Guides can be instrumental in diagnosing and resolving a high CPU usage issue caused by too many short-lived connections.

 

 

 

Identifying the Issue

 

 

Imagine you're monitoring your Azure Database for PostgreSQL - Flexible Server, and you notice an unexpected spike in CPU usage. To investigate the issue further, you decide to use the "High CPU Usage" Troubleshooting Guide.

 

1. Access the Azure portal and navigate to your Flexible Server instance.
   
2. Choose the "High CPU Usage" Troubleshooting Guide.
   

 

This guide provides you with several charts and data visualizations that can help identify the root cause of the high CPU usage. In this case, you observe a sudden increase in the "Total User Only Connections" chart, indicating that the issue might be related to too many short-lived connections.

 

 

 

Digging Deeper

 

 

To confirm the hypothesis, you can examine the "Top CPU Consuming Queries" and "Long Running Transactions" charts. If these charts don't show any significant spikes or abnormalities, it's more likely that the high CPU usage is due to excessive short-lived connections.

Resolving the Issue

 

 

Once you've identified the issue, you can follow the recommendations provided in the Troubleshooting Guide to resolve it:

 

1. Check your application's connection pooling settings and ensure they are configured optimally. Alternatively, you can enable the built-in connection pool in Azure Database for PostgreSQL - Flexible Server, PgBouncer, to help manage connections more efficiently.
   
2. Implement connection timeouts to avoid idle connections consuming resources.
   
3. Analyze your application's connection handling logic and optimize it to minimize the number of unnecessary short-lived connections.
   
4. Consider scaling your Azure Database for PostgreSQL - Flexible Server to handle more connections if needed.
   

 

By leveraging the insights and recommendations provided by the Troubleshooting Guides, you can efficiently diagnose and resolve issues like high CPU usage caused by too many short-lived connections, ensuring a more stable and performant PostgreSQL experience on Azure.

 

Remember, this is just one example of how the Troubleshooting Guides can help you tackle common issues. Don't hesitate to explore the other guides for different scenarios that may arise as you manage your Azure Database for PostgreSQL - Flexible Server.
