# Status module

The status module allows you to view or manipulate the following aspects of ThinLinc, by selecting the relevant submenu:

- Licenses allows you to view license usage.

- Load allows you to check the current workload on the ThinLinc agents.

- Sessions allows you to terminate, shadow or view details of sessions.

## Licenses

The licenses menu provides license information along with graphs showing current and historical license usage. It shows the current total number of licenses, the hard limit, the support agreement ID as well as the latest ThinLinc version the licenses are valid for. If the licenses have an expiration date, it is also shown. It also includes functionality to generate a graph displaying license usage over a specified number of days in the past.

## Load

The load page displays information about system utilization across the ThinLinc agents, enabling administrators to monitor ThinLinc usage and evaluate the capacity for adding more users to the cluster.

Each agent in the ThinLinc cluster is shown, along with the number of users who are running one or more ThinLinc sessions on the agent. The agent weights are also shown, if at least one agent has a configured `/agents/weights/<hostname>` that is different from the default value.

If an agent is set in draining mode by `/agents/draining`, the agent is shown as draining. If an agent isn’t responding to the master, the agent is shown as down.

To ensure the data is up-to-date there is a refresh button, which will verify the sessions on all agents. The time it takes to refresh the data may vary from system to system, and this operation will block interaction on the webpage while running.

## Sessions

When you select the sessions menu, a table with all currently active sessions is displayed. See Fig. 22 for an example.

To perform tasks for a user, click on the corresponding username. This will open the session details popup, which displays additional information about the chosen session. See Fig. 23 for the layout of the popup, followed by descriptions for each field.

Fig. 23 Popup with session information

- Created: A timestamp for when the session was initially created.

- Session status: The health status of the session as seen by the master machine.

- Connection status: The current connection status between the client and the session.

- Last connection: A timestamp for when the last connection was initiated and the IP address of the last connected client.

- Agent: The DNS host name of the server that is hosting the session, as seen by the master machine.

- Agent server address: The DNS host name of the server that is hosting this session, as seen by the client machine.

- Display number: Each session on a certain server has a unique number, the X Window System display number. Display zero is reserved, and never used for ThinLinc sessions.

- Terminal ID: An identification of the thin terminal. This is the terminal’s hardware address (MAC address).

- Framebuffer size: The size (resolution) of the active session.

- Local screen size: The size (resolution) of the terminal’s screen.

- Session process ID: The PID (process identification number) of the tl-session process, which is the parent for all processes belonging to a certain session.

- Command: The command line that was specified when starting this session. This is usually empty for full desktop sessions.

The two buttons in the popup do the following:

- Terminate session: By clicking this button, you can terminate a session immediately. Caution: This can lead to data loss, since applications running on the ThinLinc servers may not hold unsaved data.

- Shadow session: This button will generate a ThinLinc “launch file” (see Launching the client from a web page) that starts the native ThinLinc client, preconfigured to shadow the current user.

  Note

  The user might not be informed that shadowing is in progress if shadowing notification has been disabled. See Shadowing for details.
