Connect to Yamcs¶

Yamcs Studio can connect as a client to Yamcs Server.

Yamcs Server, or ‘Yamcs’, handles the processing, archiving and dispatching of telemetry data. Yamcs Studio is one of the possible Yamcs clients for receiving telemetry data.

To configure a Yamcs connection, select Yamcs > Connect…. This will open the Connections window where you can manage your connections.

Click Add Server to add a server connection, or Remove Server to remove the selected server connection.

The right panel contains editable details for the selected server connection:

Server URL (required)

Specify the base URL for reaching Yamcs. For example http://localhost:8090

Instance (required)

Yamcs can run multiple instances in parallel. You can think of instances like different environments, where every instance is completely separated from the other instance. While Yamcs Server may be running multiple instances in parallel, Yamcs Studio will always connects the user to one specific instance, which you have to configure here.

Type (required)

Specify the authentication mechanism. One of Standard or Kerberos.

If your Yamcs installation does not require authentication Standard and do not enter a username.

Standard Authentication

This authentication type applies the standard authentication mechanism of Yamcs where the initial authentication is done by sending a username and password to Yamcs.

User / Password (optional)

If your Yamcs instance is secured, fill in your user and password here.

Optionally, the password can be stored to your OS keychain. If you don’t do so, you will be prompted each time you attempt to connect to Yamcs.

If you wish to remove a previously stored password, click Clear.

Kerberos Authentication

Using Kerberos, Yamcs Studio assumes the username of the OS user. There is no need for a password, because the protocol allows Yamcs to verify authentication against your Kerberos Distribution Center (KDC).

The use of this mechanism requires extra configuration of your Yamcs Server, to integrate it with your Kerberos realm.
