This guide explains how to configure OpenLM with Sentinel RMS to monitor license usage and generate license statistics.

## Before you begin

To query Sentinel RMS:

- OpenLM Platform

- OpenLM Broker v25.x or higher installed on the same machine as Sentinel RMS, and approve it in [Broker Hub](https://openlm.com/documentation/cloud/data-collection/broker-hub).

## Monitoring capabilities

Monitoring features depend on whether you use OpenLM Server alone or together with OpenLM Broker.

| Report resolution | License totals | License usage | Denials reporting | Borrowed license reporting | Expiration date reporting | Multiple server redundancy |
| --- | --- | --- | --- | --- | --- | --- |
| By second | Yes | Yes | Yes | Yes | Yes | No |

- Yellow cells: Features available with OpenLM Server.

- Blue cells: Extra features available with OpenLM Server + Broker.

Using Broker also allows buffered communication and remote start/stop of the license manager service.

*Diagram of OpenLM Broker querying Sentinel RMS locally*

When Broker queries Sentinel RMS locally using RMS command-line utilities and log files, you gain full monitoring capabilities. Broker then forwards the data to OpenLM Server.

You must install and configure OpenLM Broker before continuing. See the Broker installation guide and the Broker configuration guide.

## Automatic Broker configuration

1. Open Broker UI at http://localhost:5090/.

1. Go to License Managers → Detect

1. Sentinel RMS appears

1. Validate and save

    "AspenTokens": {
      "AspenTechTokensFile": "../config/aspen_tokens_breakdown.json",
      "EnableTokenCalculations": false
    }
    ```

1. Change `EnableTokenCalculations` to `true`:

    ```json
    },
    "AspenTokens": {
      "AspenTechTokensFile": "../config/aspen_tokens_breakdown.json",
      "EnableTokenCalculations": true
    }
    ```

1. Save the file.
1. Restart OpenLM Server:

    ```powershell
    net stop "OpenLM Server"
    net start "OpenLM Server"
    ```

1. Verify in OpenLM Server that token calculations are activated.
