Monitor active queries Stay organized with collections Save and categorize content based on your preferences.
This page describes how to monitor and troubleshoot the queries that are activein your database. Monitoring these queries can help identify causes of systemlatency and high CPU usage.
On theQuery insights dashboard, you can view a summary of activetransactions and a list of transactions with associated query and statistics.The transactions are displayed by the transaction start time. If there is alarge number of queries running, then the results might be limited to asubset of total queries.
Before you begin
To monitor active queries, you can use either Cloud SQL Enterprise edition or Cloud SQL Enterprise Plus edition.
To terminate a session or a long-running transaction in active queries,you must use Cloud SQL Enterprise Plus edition for your Cloud SQL for PostgreSQL instance.
For more information aboutCloud SQL editions, seeIntroduction to Cloud SQL editions.
Required roles and permissions
To get the permissions that you need to view active queries, ask your administrator to grant you the following IAM roles on the project that hosts the Cloud SQL instance:
- View instance activity summary:Cloud SQL Viewer (
roles/cloudsql.viewer
) - View database activity summary and long-running transactions:Database Insights Viewer (
roles/databaseinsights.viewer
) - Terminate a session or long running transaction:
- Cloud SQL Editor (
roles/cloudsql.editor
) - Database Insights Operations Admin (
roles/databaseinsights.operationsAdmin
)
- Cloud SQL Editor (
For more information about granting roles, seeManage access to projects, folders, and organizations.
These predefined roles contain the permissions required to view active queries. To see the exact permissions that are required, expand theRequired permissions section:
Required permissions
The following permissions are required to view active queries:
- View database activity summary and long-running transactions:
databaseinsights.activeQueries.fetch
databaseinsights.activitySummary.fetch
You might also be able to get these permissions withcustom roles or otherpredefined roles.
Enable active queries
To enable active queries for a Cloud SQL Enterprise edition instance, do the following:
In the Google Cloud console, go to theCloud SQL Instances page.
- To open theOverview page of an instance, click the instance name.
- On theConfiguration tile, clickEdit configuration.
- In theCustomize your instance section, expandQuery insights.
- Make sureEnable Query insights is enabled.
- SelectActive query analysis.
- ClickSave.
To enable active queries for a Cloud SQL Enterprise Plus edition instance, do the following:
In the Google Cloud console, go to theCloud SQL Instances page.
- To open theOverview page of an instance, click the instance name.
- On theConfiguration tile, clickEdit configuration.
- In theCustomize your instance section, expandQuery insights.
- Make sureEnable Query insights is enabled.
- SelectEnable Enterprise Plus features.
- SelectActive query analysis.
- ClickSave.
To be able to terminate a session or long-running transaction in active queries,you must use query insights for Cloud SQL Enterprise Plus edition.
Disable active queries
To disable active queries on a Cloud SQL Enterprise edition or Cloud SQL Enterprise Plus edition instance, do the following:
In the Google Cloud console, go to theCloud SQL Instances page.
- To open theOverview page of an instance, click the instance name.
- On theConfiguration tile, clickEdit configuration.
- In theCustomize your instance section, expandQuery insights.
- Clear theActive query analysis checkbox.
- ClickSave.
View active queries
To view your active queries, complete the following steps:
In the Google Cloud console, go to theCloud SQL Instances page.
To open theOverview page of an instance, click the instance name.
Do one of the following to display theQuery insights dashboard:
- Select theQuery insights tab.
- ClickGo to Query insights for more in-depth info on queries and performance.TheQuery insights dashboard opens. It shows details about the instanceat the top.
Click theActive queries tab.
From here, you can modify the query information that appears in theLongest running transactions table:
- Database: filters query load on a specific database or all databases.
- User: filters query load from a specific user account.
Summary scorecard of all active queries: provides an overview of allthe active queries by displaying the total connections based on thefollowing parameters:
- Distribution of active connections categorized by connection state.
- Distribution of active transactions based on transaction state.
- Distribution of query durations.
- Longest running transactions: provides an overview of the top 50running queries (in theactive andidle in transaction state) based ondescending execution time. You can filter and sort active queries in thetable.
View normalized active queries
You can view a list of top long-running transactions with normalized activequeries on theQuery insights dashboard. A normalized active query removessensitive data and returns a digest. The digest is the same for different valuesused in the following example:
Regular queries
select * from test_table where id=1;
select * from test_table_where id=2;
Digest or normalized query
select * from test_table where id=?;
A query that runs in different sessions is displayed as different entries on thedashboard.
View top longest running transactions
TheLongest running transactions table on theQuery insights dashboardcontains the following columns:
Column name | Description |
---|---|
Process ID | Unique identifier of the connection or thread ID. |
Query | SQL query text. |
Status | Status of the connection. |
Session duration | Duration of the last session running. |
Transaction duration | Duration of the active transaction running. |
Query duration | Duration of the last query running in that transaction. |
Wait event type | Wait event type of the occurring wait event. |
Wait event | Occurring wait event. |
Database | Database name on which this connection is running. |
Application name | Application name on which this connection is running. |
User name | Name of the user connected to the database. |
Client address | Specific IP address of the client that sent a query. |
Action | Contains a link for terminating a transaction. |
The display is refreshed every 60 seconds automatically.
Terminate a process
To terminate a process or long-running transaction in active queries,you must use Cloud SQL Enterprise Plus edition and enable bothActive query analysisandquery insights for Cloud SQL Enterprise Plus edition.
Long running operations can take longer to terminate.
To terminate a query or transaction, complete the following steps:
- In theLongest running transaction table, select a query.
- In theAction column, clickTerminate connection.
- In theTerminate connection window, clickConfirm.
If the system successfully terminates the query or transaction, then a successmessage appears. The system also performs a rollback if needed.
Note: IfTerminate isn't available, then you might have insufficientIAM permissions. For more information, seeBefore you begin.What's next
