# NMS Setup

This article discusses the initial setup of **NMS** (Network Monitoring System) in the Kentik portal.

> [!NOTE]
> **Note:**For an overview of the initial Kentik setup tasks, see [**Getting Started**](/v1/docs/getting-started).

*NMS Setup discovers devices for NMS monitoring.*

## About NMS Setup

Kentik’s NMS (Network Monitoring System) discovers and monitors devices within your infrastructure. Setup is managed via the [**NMS Setup Wizard**](/v1/docs/nms-setup#nms-setup-wizard), which configures the [**Universal Agent**](/v1/docs/universal-agents) to collect metrics and transmit them to the Kentik SaaS.

### Access the NMS Setup Wizard

**New/Trial Customers**:

- Go to the **Welcome to Network Observability** page during onboarding.
- NMS setup is listed as one of the setup tasks on the left.

**Existing Deployments**:

- From the main portal nav menu, open the NMS Devices page.
- Select the Manage dropdown in the subnav and click**Discoveries** to open the [**NMS Discoveries**](/v1/docs/nms-setup#nms-discoveries-page-ui) page.
- Click **Discover Devices** to open the wizard.

### How NMS Polling Works

Unlike non-NMS applications involving SNMP, NMS requires the [**Universal Agent**](/v1/docs/universal-agents) to be deployed within your network. The following default polling intervals apply:

| Metric Type | Polling Interval |
| --- | --- |
| Device Status, CPU, Memory, Interfaces | 1 minute |
| All other metrics | 5 minutes |

> [!NOTE]
> **Note:** These intervals can be overridden by using Streaming Telemetry (ST) for supported devices (see [**NMS via Streaming Telemetry**](/v1/docs/nms-setup#nms-via-streaming-telemetry)).

## NMS Setup Wizard

The setup process is divided into three main steps: deployment, credentialing, and discovery.

### Step 1: Deploy the Universal Agent

1. Navigate to the **NMS Setup** page.
2. Select your deployment method: Docker or Linux.
3. Copy the provided install command.
  - Optional*:* If using a web proxy, set the `https_proxy` variable as shown in the UI.
4. Run the command in the terminal on the host machine.
5. Once the agent appears in the Select an Agent list, click **Use this Agent**.

> [!TIP]
> **TIP**: The SNMP/ST capability of the Universal Agent will be installed automatically by the wizard. To install other capabilities for it, or any other agent, see [**Install a Capability**](/v1/docs/universal-agents#install-a-capability).

### Step 2: Add Subnets & Credentials

1. In the******IP Range**field, enter a comma-separated list of IP ranges to scan.
2. From the **Credentials**dropdown, either select existing SNMP credentials or click **New Credential**and specify the following:
  - **Type:** SNMP version (v1, v2c, or v3).
  - **Credential Name**: Any user chosen name (no spaces).
  - **Community:** The SNMP community string configured on your devices.
3. Confirm the **Collection Agent** and click **Start Discovery**.

### Step 3: Discover and Import

The agent scans the provided ranges. Results populate in real-time.

1. Review the Discovered Devices list.

> [!TIP]
> **TIP**: Click the customize button to choose which columns of information are shown in the list.
2. Uncheck any devices you do not wish to monitor.
3. Click **Add Devices** to begin data collection and open the [**NMS Devices**](/v1/docs/nms-devices#nms-devices-page)****page.

## Manage NMS Discoveries

Device discovery may take time depending on network size. You can monitor progress via the status indicator in the main navbar or by clicking **Manage Discoveries** on the [**NMS Discoveries**](/v1/docs/nms-setup#nms-discoveries-page-ui)****page.

### Discovery Status Types

- **In Progress:** Scanning is active; an estimated time remaining is provided.
- **Finished:** All IPs have been scanned.
- **Started/Completed:** Timestamps for the discovery window.

## NMS via Streaming Telemetry

Streaming Telemetry offers a modern alternative to traditional SNMP polling.

> [!NOTE]
> **Notes:**
> 
> - Kentik also has limited support for collection via ST of data for the Kentik Data Engine (see [**SNMP and ST KDE Support**](/v1/docs/snmp-and-streaming-telemetry#snmp-and-st-kde-support)).
> - For information about differences between SNMP and Streaming Telemetry, see [**SNMP vs. Streaming Telemetry**](/v1/docs/snmp-and-streaming-telemetry#snmp-vs-streaming-telemetry).

### Comparison: SNMP vs. ST

- **Efficiency:** ST uses a subscription model, reducing CPU load on devices.
- **Granularity:** Supports sub-second data collection (defaulting to 30s in Kentik).
- **Accuracy:** Data is timestamped at the source, eliminating transit-time jitter.
- **Data Availability**: Some vendors (e.g., Juniper) are making new data types available only via ST.

> [!NOTE]
> **Note:**For assistance with any obstacles to your adoption of ST, contact Kentik (see [**Customer Care**](/v1/docs/customer-care)).

### Supported ST Protocols

| Feature | Supported | Not Supported |
| --- | --- | --- |
| Transport | gRPC | TCP, UDP |
| Session | Dial-in (gNMI) | Dial-out |
| Encoding | JSON, Protobuf (GPB) | XML |

### Implementing ST (Two-Phase Process)

To use ST, a device must first be discovered via the [**NMS Setup Wizard**](/v1/docs/nms-setup#nms-setup-wizard) to map its SNMP components.

1. **Device Config:** Configure your hardware (Cisco, Juniper, or Arista) for gNMI Dial-in (see Kentik’s [**Configuration Repo**](https://github.com/kentik) for vendor-specific examples).
2. ![](https://cdn.us.document360.io/082e25b5-afce-42d4-8f47-70bd3f1d02b7/Images/Documentation/image(61).png)**Kentik Portal Config:** Navigate to Device Settings > **Streaming Telemetry** and enable **Dial-In from Universal Agent**.

### What Changes After Enabling ST?

Once enabled, the Universal Agent stops polling SNMP for CPU, memory, and interface stats, switching to ST intervals:

- **Default Metrics:** 30-second collection.
- **CPU Metrics:** 2-second collection (visible as live updates on the **NMS Devices** page).

> [!NOTE]
> **Note:** SNMP polling **continues** for non-telemetry data such as hardware make/model and BGP monitoring.

### View Results

ST data is normalized into the same schema as SNMP. You can view integrated results in the [**NMS Dashboard**](/v1/docs/nms-dashboard), [**Metrics Explorer**](/v1/docs/metrics-explorer), and [**NMS Devices**](/v1/docs/nms-devices) pages. To verify if a device is actively using ST, check the **Dial-In from Universal Agent** checkbox status in the device's Settings dialog (see [**Device ST Settings**](/v1/docs/device-settings#device-st-settings)).
