Hiding Instances from the Admin Host

By default, Arc detects and displays all TM1 instances available on the local server and on any admin hosts defined in settings.yml. You can use the instancestohide setting to suppress specific instances from appearing in the Arc instance list.

When to Use This Setting

This is useful when:

• A TM1 instance's port is blocked or the instance is unavailable, causing Arc to wait before timing out.

• You want to prevent developers from accidentally connecting to certain instances (e.g. a production instance visible via the admin host).

• You want to reduce clutter in the Arc instance list.

Configuration

Open settings.yml in the Arc installation directory and add the instancestohide parameter. You can specify instances in two formats:

Inline list format:

Multi-line list format:

Replace dev and prod with the exact names of the TM1 instances you want to hide (as they appear in the admin host).

After Updating settings.yml

1. Save settings.yml.

2. Refresh Arc in the browser.

3. Clear the cache (SHIFT + F5) to ensure the updated instance list is loaded.

The hidden instances will no longer appear in the Arc left panel.
