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

## Requirements

To query Sentinel RMS:

- Install OpenLM Server v4.3 or higher on a machine in your organization (or use a Cloud account).
- *(Optional)* Install OpenLM Broker v4.x or higher on the Sentinel RMS machine to take advantage of advanced monitoring features.

## Monitoring capabilities

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

| Feature                  | Resolution   | License totals | License usage | Denials reporting | Borrowed license reporting | Expiration date reporting | Multiple server redundancy |
|---------------------------|--------------|----------------|---------------|-------------------|----------------------------|---------------------------|----------------------------|
| Support                   | By second    | ✔              | ✔             | ✔                 | ✔                          | ✔                         | ❌                        |

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

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

## Monitoring with OpenLM Server only

*Diagram of OpenLM Server querying Sentinel RMS directly*

OpenLM Server can query Sentinel RMS directly through RMS command-line tools. This option provides license totals and usage only.

### LM tools configuration

To allow OpenLM Server to query Sentinel RMS:

1. Copy `lsmon.exe`, `lservnt.exe`, and `lsapiw32.dll` from the Sentinel RMS machine (for example,  
   `C:\Program Files (x86)\Common Files\SafeNet Sentinel\Sentinel RMS License Manager\WinNT`)  
   to the OpenLM Server installation folder (for example,  
   `C:\Program Files\OpenLM\OpenLM Server\LM`).
2. Open **EasyAdmin → Start → Administration → License Manager Servers**.
3. Select LM type **RMS**.
4. Set the full path to the RMS executable (`lsmon.exe`).
5. Select **Save**.

### Adding a new Sentinel RMS server

After setup:

1. Open the **License Servers** tab.
2. Select **Add LM**.
3. Enter a **Display Name**.
4. Select **RMS** as LM type.
5. Enter **Server Host Name** and **Port** (for example, 5093).
6. Set the correct **Time Zone**.
7. Turn **Use Broker** toggle **off**.
8. Select **Save**.

## Monitoring with OpenLM Server and Broker

*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.

:::note
You must install and configure OpenLM Broker before continuing.  
See the [Broker installation guide](https://www.openlm.com/application-notes-v3-0/installing-openlm-v3-0/broker-comprehensive-installation-guide-an4004b/) and the [Broker configuration guide](https://openlm.com/documentation/legacy/openlm-broker/openlm-broker-configuration).

### Activating Sentinel RMS usage log

By default, RMS does not record usage logs. Activate logging with the `-l <usage-log-filename>` argument in the RMS startup command (`lservnt`/`lserv`) or the `LSERVOPTS` environment variable.  

For detailed steps, see the [Sentinel RMS documentation](https://docs.sentinel.gemalto.com/softwareandservices/rms/RMSDocumentation/SysAdmin/Content/Configuring_%20License_Manager.htm).

Logs are required for denial monitoring.

### OpenLM Broker configuration

### Automatic detection

In the Broker configuration tool:

1. Select **Detect**.  
   If the Sentinel RMS service is running, Broker detects the port and utility path automatically.  

:::tip
Detection may not capture all settings. Continue with manual configuration if needed.
:::

*Automatic Broker detection*

### Manual configuration

If detection fails:

1. Select **Add Port** → enter RMS port (for example, 5093).
2. Select **RMS** as license manager type.
3. Under **Commands**, update the utility path to the RMS tools folder.
4. (Windows only) Check **Use Service** and enter *Sentinel RMS License Manager*.
5. Select **Apply**.
6. Run a **data_inquiry** to verify valid output.
7. Add the RMS usage log under **Log Files**.
8. Restart Broker.

*Manual Broker configuration*

### Broker UI configuration

Alternatively, configure through the Broker UI in your browser:

1. Go to **License Manager** → **Add License Manager**.
2. Select **RMS**, enter port, and add.
3. Check the executable path.
4. (Windows only) Set service to *Sentinel RMS License Manager*.
5. Run **data_inquiry** and verify output.
6. Add vendor information if required.
7. Configure **Log Files** for RMS usage logs.
8. Save changes.

### OpenLM Server configuration

If Broker was configured successfully, Sentinel RMS is added automatically to OpenLM Server.  

If automatic setup fails, configure manually:

1. In OpenLM Server configuration, add Sentinel RMS server.  
2. Enter hostname and port from Broker.  
3. Check **Use Broker**.  
4. Save.

## Activating token calculator (Server v24.6+)

By default, token calculations are deactivated. To activate:

1. Back up `appsettings.json`.
2. Open the file (default: `C:\Program Files\OpenLM\OpenLM Server\bin`).
3. Locate this section:

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

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

	5.	Save the file.
	6.	Restart OpenLM Server:

```shell
net stop "OpenLM Server"
net start "OpenLM Server"
```

	7.	Verify in OpenLM Server that token calculations are enabled.

## Verifying Sentinel RMS configuration

To confirm monitoring is active:
	1.	Open EasyAdmin UI.
	2.	Go to Start → Widgets → License Servers.
	3.	Check that Sentinel RMS servers appear in the list.

A green circle indicates an active connection.
It may take up to 3 minutes for new connections to display as active.
