    Managed Service for OpenTelemetry:Manage applications and tags

    Last Updated:Mar 11, 2026

    When you run multiple applications in Managed Service for OpenTelemetry, you need a way to control how servers are displayed, manage data collection costs, and organize applications for quick filtering. The Application Settings page in the Tracing Analysis console lets you:

    • Switch server display between IP addresses and hostnames

    • Enable or disable data collection to control billing

    • Create and assign tags to group and filter applications

    • Delete applications that are no longer needed

    Tags are labels you attach to applications to organize and filter them across your account. For example, assign tags like env:production or team:backend to quickly locate relevant applications in the console.

    Prerequisites

    Before you begin, make sure that you have:

    • An Alibaba Cloud account with Managed Service for OpenTelemetry activated

    • At least one application reporting trace data

    Open the Application Settings page

    1. Log on to the Tracing Analysis console.

    2. In the left-side navigation pane, click Applications.

    3. In the top navigation bar, select a region.

    4. Click the name of the application to configure.

    5. In the left-side navigation pane, click Application Settings.

    Display servers by hostname

    By default, servers are identified by IP addresses. If hostnames are more useful for your team, switch to hostname-based display.

    Servers identified by IP addressServers identified by hostname

    1. On the Custom Configuration tab, locate the Display Settings section.

    2. Turn on Show Host Name.

    3. Click Save.

    Note This change applies only to newly collected data. Existing data retains the original IP address display.

    Stop or resume data collection

    Disable data collection to stop billing for an application. When data collection is disabled, the application stops incurring charges but all reported data is discarded.

    Important

    After you disable data collection, all reported data is discarded. If the application calls downstream services, traces are incomplete because Tracing Analysis cannot collect the full call chain. Additionally, if the Capture Data parameter on the Cluster Configurations tab is set to Enable or Disable, that cluster-level setting overrides the per-application setting.

    1. In the Data Capturing Settings section, set Capture Data to Disable.

    2. Click Save.

    To resume data collection, set Capture Data to Enable and click Save.

    Enable or disable tags for an application

    1. Click the Tags tab.

    2. In the Manage Application Tags section, select the tags to enable and clear the tags to disable.

    Manage tags across your account

    Create, rename, or delete tags that apply to all applications under your account.

    1. Click the Tags tab.

    2. In the Manage Application Tags section, click Manage Application Tags.

    3. In the Manage Application Tags dialog box, perform the following operations:

      • Create a tag: Click the + icon and enter a tag name.

        Important Deleting a tag detaches it from all applications.

    4. Click OK.

    5. In the confirmation message, click OK.

    Delete an application

    Before you delete an application, make sure the application no longer needs to report trace data.

    1. Click the Delete tab.

    2. In the Delete Application section, click Delete.

    3. In the confirmation message, click Delete.
