Troubleshoot slow queries

To use AI assistance with troubleshooting your slow queries, go to the Query insights dashboard for your Cloud SQL instance in Google Cloud console.

Top queries table

You can start troubleshooting slow queries with AI assistance in the Top queries table section of the Query insights dashboard.

Cloud SQL can help you identify which queries are performing slower than average during a specific detection time period. After you select a time range in the Query insights dashboard, Cloud SQL checks whether any queries are performing slower than average by using a detection time period of 24 hours before the end of your selected time range.

When you adjust the time range filter of the Database load chart, or any other filter such as database or user, Cloud SQL refreshes the Top queries table and reruns anomaly detection based on the new list of queries and an updated detection time period.

For Cloud SQL Enterprise Plus edition instances, the following occurs when Cloud SQL detects an anomaly:

If a query is running slower than expected, then a Warning warning_spark icon is displayed. When you click either icon, Gemini Cloud Assist is used to help analyze the query execution and offers observations about what might have caused any issue. Based on these observations, Gemini Cloud Assist generates a hypothesis that can help you address the issue.

To troubleshoot slow queries in the Top queries table in the Query insights dashboard, do the following:

1. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. To open the Overview page of an instance, click the instance name.
3. In the SQL navigation menu, click Query insights.

5. In the Top queries table, under the Queries tab, review the list of queries for your database.
6. If a Warning warning_spark icon appears next to the query's Avg execution time (ms) value for a query, then Cloud SQL has detected an anomaly in your query performance. Cloud SQL checks for anomalies within the 24-hour time period that occurs before the end of your selected time range.
7. Click the Warning warning_spark icon.
8. In the Query is slower than usual dialog, click New Investigation to start troubleshooting with AI assistance from Gemini Cloud Assist. After about two minutes, the Investigation details pane opens with the following sections:
   • Issue. A description of the issue being investigated, including the investigation’s start and stop time.
   • Observations. A list of observations about the issue. For example, these can include lock contention details, such as a longer than expected lock wait ratio for the query.
   • Hypotheses. A list of AI-recommended actions to take to help address the slow running query.

9. If you want to see all investigations associated with the query, in the Query is slower than usual dialog, click View all investigations. The Gemini Cloud Assist page opens where you can view all currently running and previously completed investigations. You can filter the page by project or label, for example, to find the specific investigation you need.

   Alternatively, to see all previous investigations, click the Notifications icon, then select a notification associated with any investigation to open the Gemini Cloud Assist page.

6. Optional: Use the Time range filter to select either 1 hour, 6 hours, 1 day, 7 days, 30 days or a custom range. When you adjust the Time range filter of the Query details page , or any other filter such as Database or User, Cloud SQL reruns anomaly detection.
   While the Time range filter you choose applies to most results, the Analysis time period is always set to 48 hours.
7. If Cloud SQL doesn't detect an anomaly for the query, then you can still run an analysis on the query by clicking the Investigate button in the Query latency card.

Analyze query latency

Using AI assistance, you can analyze and troubleshoot the details of your query latency.

Analysis time period

The analysis time period consists of the 24 hours that occur before the end of the time range that you select in the Database load chart of the Query insights dashboard or the Query details page. Cloud SQL uses this time period to compare baseline metrics with the metrics retrieved during the time period of the anomaly.

On the Query details page, for Cloud SQL Enterprise Plus edition, if Cloud SQL has detected an anomaly with the query, then after you select the query from the Query insights dashboard, Cloud SQL performs a baseline performance analysis for the query using the last 24 hours from the end of the anomaly. If Cloud SQL hasn't detected an anomaly with the query and runs anomaly detection on the query again, then Cloud SQL uses 48 hours before the end of the selected time range as the performance baseline for the analysis time period.

Detected anomaly period

The detected anomaly period is applicable to Cloud SQL Enterprise Plus edition instances only.

The detected anomaly period represents a time period when Cloud SQL finds an anomalous change in query performance. Cloud SQL uses the baseline performance measured for the query during the analysis time period.

If Cloud SQL detects multiple anomalies for a query within a selected time period, then Cloud SQL uses the last detected anomaly.

Examples of query performance prompts

You can also use Gemini Cloud Assist to enter prompts to help you improve the performance of your queries. Gemini Cloud Assist answers questions for the selected Cloud SQL instance and database.

Prompt	Type of response
What are the top queries by latency in my database?	Summaries of queries sorted by latency. Gemini scopes the response by the time range filter selected in the query insights database load chart. Guidance on how to identify and sort queries by latency.

Analyze high database load

Using AI assistance, you can analyze and troubleshoot the details of your database load.

Analysis time period

Cloud SQL analyzes your database for the time period that you select in your database load chart from the Query insights dashboard or the Instance overview page. If you select a time period of less than 24 hours, then Cloud SQL analyzes the entire time period. If you select a time period greater than 24 hours, then Cloud SQL selects only the last 24 hours of the time period for analysis.

To calculate the baseline performance analysis of your database, Cloud SQL includes 24 hours of a baseline time period in its analysis time period. If your selected time period occurs on a day other than Monday, then Cloud SQL uses a baseline time period of the 24 hours previous to your selected time period. If your selected time period occurs on a Monday, then Cloud SQL uses a baseline time period of the 7th day previous to your selected time period.

Metrics analysis

When Cloud SQL starts the analysis, Cloud SQL checks for significant changes in the various metrics, including but not limited to the following:

• Queries per second (QPS)
• CPU
• Memory
• Disk I/O

Cloud SQL compares the baseline aggregated data for your database within the performance data of your analysis time window. If Cloud SQL detects a significant change in threshold for a key metric, then Cloud SQL indicates a possible situation with your database. The identified situation might explain a root cause for the high load on your database over the selected time period.

Recommendations

When Gemini Cloud Assist completes analysis, the Hypotheses section of the Investigation details pane lists actionable insights to help remediate the issue.

For some situations, based on the analysis, there might not be a recommendation.
