Connect to Multiple Admin Hosts

By default, Arc connects to the admin host on the local computer (i.e. the server where Arc is installed). To monitor TM1 instances across multiple servers, you can add additional admin hosts to the Arc configuration.

Configuration

Edit the settings.yml file in your Arc installation directory and add an extra line for each remote admin host:

adminhosts:
  - https://localhost:5898
  - https://tm1server2:5898
  - https://tm1server3:5898

Each admin host entry should use the server's hostname or IP address and the TM1 admin host REST API port (default: 5898).

Prerequisites

The TM1 REST API must be enabled on each TM1 instance you want to connect to. Set HTTPPortNumber in tm1s.cfg for each instance.
The admin host port (5898) and REST API port must be accessible from the Arc server (check firewall rules).

For instructions on enabling the TM1 REST API, see the Arc System Requirements page.

After Updating settings.yml

Restart Arc after saving changes to settings.yml for the new admin hosts to take effect.

Alternative: Connect Directly via REST API

If the admin host port is blocked (e.g. in cloud environments), you can connect to individual TM1 instances directly using the REST API port instead. See Connect to a TM1 Instance Directly via the REST API.
