# 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:

## 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.

## 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

## 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.
