# Alerts Tab

Netdata provides hundreds of pre-configured health alerts to notify you when an anomaly or performance issue affects your node or its applications.

## Raised Alerts Tab

The **Raised Alerts** tab shows all current alerts in your Room that are in a **warning** or **critical** state.

### Alert Table Overview

The table provides key details about each active alert:

| Column               | Description                                                          |
|----------------------|----------------------------------------------------------------------|
| **Alert Name**       | The name of the alert; click to view alert details.                  |
| **Status**           | Current state: Warning or Critical.                                  |
| **Class**            | The alert's class (e.g., Latency, Utilization).                      |
| **Type & Component** | The system type and component involved.                              |
| **Role**             | The notification role assigned to the alert.                         |
| **Node Name**        | The node where the alert was triggered.                              |
| **Silencing Rule**   | Whether silencing rules are applied.                                 |
| **Actions**          | Options to create silencing rules or ask Netdata Assistant for help. |

Use the **gear icon** (top right) to control which columns are visible. Sort alerts by clicking on column headers.

## Filtering Alerts

Filter the alert list using the right-hand bar:

| Filter Option              | Purpose                                                                          |
|----------------------------|----------------------------------------------------------------------------------|
| **Alert Status**           | Filter by status (Warning, Critical).                                            |

## Viewing Alert Details

Click on an alert name to open the **alert details page**, which provides:

| Section                      | Description                                                  |
|------------------------------|--------------------------------------------------------------|
| **Latest / Triggered Time**  | Shows when the alert was last triggered.                     |
| **Description**              | Includes a detailed explanation of the alert.                |
| **Netdata Advisor Link**     | Links to related Netdata Advisor guidance.                   |
| **Triggered Chart Snapshot** | Visualizes the chart at the alert’s trigger time.            |
| **Alert Metadata**           | Shows node name, chart instance, type, component, and class. |
| **Configuration**            | Displays the alert's configuration parameters.               |
| **Instance Values**          | Provides node instance details.                              |

At the bottom of this page, click **View alert page** to open a dynamic view where you can:

- Run metric correlations.
- Navigate to the specific node’s chart that triggered the alert.

## Silencing Alerts

In the **Raised Alerts** tab:

- The **Silencing column** shows whether a silencing rule exists for an alert.
- The **Actions column** allows you to:
    - Create a new [silencing rule](/docs/alerts-and-notifications/notifications/centralized-cloud-notifications/centralized-cloud-notifications-reference.md#alert-notification-silencing-rules).
    - Ask AI to troubleshoot the alert.

:::note

Cloud alert silencing rules are available on Netdata Cloud for Community and Paid plans (anonymous access cannot create rules).

Users can also silence or disable alerts at the Agent level by editing alert configuration. For example, set `to: silent` in the alert's `health.d/*.conf` file and run `sudo netdatacli reload-health` to stop notifications, or use `enabled alarms = !alert_name *` in `netdata.conf` to exclude specific alerts entirely (requires restarting the Agent). See [manual configuration](/src/health/REFERENCE.md) for step-by-step instructions.

:::

## Creating and Tuning Alerts

From the Alerts tab, you can create new alerts or tune existing ones:

- **[Alerts Automation](/docs/netdata-ai/alerts-automation/alerts-automation.md)** — Describe what you want in plain English and let AI generate the alert configuration, including thresholds and tuning parameters
- **[Alerts Configuration Manager](/docs/alerts-and-notifications/creating-alerts-with-netdata-alerts-configuration-manager.md)** — Visual UI wizard for manual alert creation and fine-tuning
- **[Manual configuration](/src/health/REFERENCE.md)** — Edit `health.d/*.conf` files directly for full control

:::note

**Alerts Automation** and the **Alerts Configuration Manager** require a Netdata Cloud paid plan.
See [Netdata OSS limitations and feature availability](/docs/netdata-oss-limitations.md) to confirm plan requirements.
Community plan users can still create and tune alerts using [manual configuration](/src/health/REFERENCE.md).

:::

## Alert Configurations Tab

The **Alert Configurations** tab shows the configuration of all running alerts in your Room.

:::note

"Running alerts" are alerts attached to metrics that are actively being collected. Pre-configured alerts that do not match your setup may not appear here.

### Configuration Table Overview

| Column             | Description                                         |
|--------------------|-----------------------------------------------------|
| **Alert Name**     | The name of the alert; click to view configuration. |
| **Node Name**      | The node where this configuration applies.          |
| **Status**         | Whether the alert is active or silenced.            |
| **Silencing Rule** | Indicates if silencing rules are applied.           |
| **Actions**        | Explore configuration or ask the Netdata Assistant. |

Use the **gear icon** to adjust which columns are displayed.

## Viewing Alert Configuration

From the **Actions column**, click **Show Configuration** to:

| Action              | Outcome                                                      |
|---------------------|--------------------------------------------------------------|
| **Explore by Node** | View configurations split by node.                           |
| **View Alert Page** | See full alert details, including configuration and history. |

This allows you to investigate:

- When the alert last triggered.
- All configuration parameters per node.
