Serverless App Engine (SAE) integrates with Application Real-Time Monitoring Service (ARMS) to provide multiple monitoring features. After you enable ARMS Premium monitoring, you can quickly locate faulty and slow APIs, detect memory leaks, and identify system bottlenecks. This greatly improves the efficiency of diagnosing online issues. This topic describes how to enable or disable application monitoring and view monitoring data in SAE.
Enable application monitoring
Professional Edition applications
SAE Professional Edition applications integrate with Premium application monitoring. This feature is free of charge but must be enabled manually.
After you enable application monitoring, the system injects a built-in agent into each instance. This agent consumes approximately 0.2 cores of CPU and 200 MB of memory. Plan your resources accordingly.
Create an application
On the SAE Application List page, select a destination region and namespace in the top navigation bar, and then click Create Application. On the Application Basic Information page, configure the parameters and click Next: Advanced Settings.
Change a running application
WarningAfter you redeploy an application, the application is restarted. To prevent unpredictable errors such as business interruptions, we recommend that you deploy applications during off-peak hours.
On the SAE Application List page, select a destination region and namespace in the top navigation bar. Click the ID of the target Application to open the application details page.In the navigation pane on the left, click Basic Information. In the upper-right corner, click Deploy Application.
Change a stopped application
On the SAE Application List page, select a destination region and namespace in the top navigation bar. Click the ID of the target Application to open the application details page.Click Basic Information, and then click Modify Application Configuration.
Find and expand the Application Monitoring section, and then turn on the switch for application monitoring.
NoteIf you deploy your application using an image, you must manually install the corresponding probe when you build the custom image.
For a Golang application, install the Golang probe. For more information, see Install the probe for a Golang application.
For a Python application, install the Python probe. For more information, see Install the probe for a Python application.
If you deploy your application using a code package, no extra operations are required because the system automatically integrates the corresponding probe into the image when it builds the image from the code package.
Complete the application deployment.
Standard Edition applications
Standard Edition SAE applications integrate with Basic application monitoring. This feature is automatically enabled after application deployment and requires no extra operations.
To use the Premium application monitoring feature, you must enable Premium monitoring, which incurs additional charges.
Manage application probe versions
This feature is in a beta testing phase and is available by invitation only. If you want to use this feature, contact the technical staff in DingTalk group 32874633 to enable it.
Create an application
On the SAE Application List page, select a destination region and namespace in the top navigation bar, and then click Create Application. On the Application Basic Information page, configure the parameters and click Next: Advanced Settings.

Find and expand the Probe Configuration section, and then select the desired Probe Version.
Complete the application deployment.
Change application probe versions in batches
This feature is in a beta testing phase and is available by invitation only. If you want to use this feature, contact the technical staff in DingTalk group 32874633 to enable it.
On the SAE Batch Operations page, select a destination region and namespace from the top navigation bar.
On the Application Dimension tab, configure the following parameters:
Set Task Type to Application Operation.
Set Operation To Perform to Change Probe Version.
Select the desired Probe Version Number.
Select an Effective Policy.
Take Effect On Next Deployment: The configuration does not take effect immediately. It takes effect the next time you manually deploy the application.
Take Effect Immediately: The application is redeployed immediately after the configuration is complete. We recommend that you perform this operation during off-peak hours.
Select one or more applications.
Click Create Task and follow the on-screen instructions.
Disable application monitoring
Professional Edition applications
On the Basic Information page of the target application, click Deploy Application.
Find and expand the Application Monitoring section, and then turn off the switch for application monitoring.
Click OK.
Standard Edition applications
On the Basic Information page of the target application, click More in the upper-right corner, and then click Stop Application Monitoring.
In the Disable Application Monitoring dialog box that appears, click OK.
