Alerts and Notifications
Netdata provides two ways to send alert notifications. You can use either one—or both—at the same time.
Alerts are based on each node's health status. You can change thresholds, add new alerts, or silence specific ones using Netdata's alerting system.
How Alert Notifications Work
| Method | Where Alerts Are Sent From | Customization | Highlights |
|---|---|---|---|
| Netdata Cloud | Cloud UI | Medium | Centralized alerting using connected nodes’ health status |
| Netdata Agent | Local Netdata Agent | High | Node-level alerting with wide integration support |
You can enable one or both methods depending on your needs.
Quick Start
Use this table to choose and set up your preferred alerting method:
| Option | Setup Location | Setup Effort | Best For |
|---|---|---|---|
| Netdata Cloud | In the Cloud UI | Low | Teams managing multiple nodes |
| Netdata Agent | On each Netdata node | Medium | Full control and flexibility |
Example 1: Set Up Alerts via Netdata Cloud
- Connect your nodes to Netdata Cloud.
- In the UI, go to:
Space → Notifications. - Choose an integration (e.g. Slack, Amazon SNS, Splunk).
- Set alert severity filters as needed.
→ See all supported Cloud integrations
Example 2: Set Up Alerts via Netdata Agent
- Open the notification config:
sudo ./edit-config health_alarm_notify.conf
- Enable your preferred method, for example email:
SEND_EMAIL="YES"
DEFAULT_RECIPIENT_EMAIL="you@example.com"
- Ensure your system can send mail (via
sendmail, SMTP relay, etc.). - Restart the agent:
sudo systemctl restart netdata
→ See all Agent-based integrations
About the Agent's Health Monitoring
The Netdata Agent continuously monitors system health and performance. It includes:
- Hundreds of pre-configured alerts (covering system, app, and service metrics)
- No setup required — works out of the box
- Dynamic customization — you can fully control how, when, and what triggers an alert

- Adjust thresholds
- Write custom alert conditions
- Silence alerts temporarily or permanently
