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

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.
- 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 — Describe what you want in plain English and let AI generate the alert configuration, including thresholds and tuning parameters
Alerts Configuration Manager — Visual UI wizard for manual alert creation and fine-tuning
Manual configuration — 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.
