When monitoring a Python application with Application Real-Time Monitoring Service (ARMS), you may need to adjust trace sampling rates or temporarily pause data collection without restarting the application. The Custom Configurations page provides these controls, along with the ability to copy settings across applications and set global defaults.
For information about how to use the ARMS API to configure these settings, see SaveTraceAppConfig.
Prerequisites
Before you begin, make sure that you have:
An ARMS agent installed for the application. For details, see Application Monitoring overview
Open the Custom Configurations page
Log on to the ARMS console.
In the left-side navigation pane, choose .
In the top navigation bar, select a region, then click the name of the target application.
NoteThe icon in the Language column indicates which monitoring service the application uses. The
icon indicates Application Monitoring. A hyphen (-) indicates Managed Service for OpenTelemetry.In the top navigation bar, choose .
Configure trace sampling
Python applications support fixed-rate sampling only. To set the sampling rate:
In the Sampling Settings section, set the sampling rate.
Click Save.
Pause or resume monitoring
Toggle the Pause application monitoring switch in the Probe switch settings section to enable or disable application monitoring.
This switch takes effect immediately. No application restart is required. While monitoring is paused, the system no longer monitors the application.
Copy settings to other applications
You can reuse the current application's configuration by copying it to one or more other applications.
Copy a single configuration section
In the target section, click Save and Copy to Other Applications.
If the Current settings are not saved message appears, click OK to save first, then click Save and Copy to Other Applications again.
In the dialog box, select the target applications and click OK.
Copy all configuration sections
At the bottom of the page, click Save and Copy to Other Applications.
If the Current settings are not saved message appears, click OK to save first, then click Save and Copy to Other Applications again.
In the dialog box, select the target applications and click OK.
Save current settings as the global default
Save the current application's settings as the default configuration for all new applications.
At the bottom of the page, click Save Current Application Settings as Global Default Configurations.
If the Current settings are not saved message appears, click OK to save first, then click Save Current Application Settings as Global Default Configurations again.
In the confirmation dialog, click OK.
New applications created after this point automatically inherit these settings.
