Every Netdata Agent comes with hundreds of pre-installed health alarms designed to notify you when an anomaly or performance issue affects your node or the applications it runs.
As soon as you launch a Netdata Agent and claim it, you can view active alarms in both the local dashboard and Netdata Cloud.
You can see active alarms from any node in your infrastructure in two ways: Click on the bell 🔔 icon in the top
navigation, or click on the first column of any node's row in Nodes. This column's color changes based on the node's
health status: gray is
CLEAR, yellow is
WARNING, and red is
The Alarms panel lists all active alarms for nodes within that War Room, and tells you which chart triggered the alarm, what that chart's current value is, the alarm that triggered it, and when the alarm status first began.
Use the input field in the Alarms panel to filter active alarms. You can sort by the node's name, alarm, status, chart that triggered the alarm, or the operating system. Read more about the filtering syntax to build valuable filters for your infrastructure.
Click on the 3-dot icon (
⋮) to view active alarm information or navigate directly to the offending chart in that
node's Cloud dashboard with the Go to chart button.
The active alarm information gives you details about the alarm that's been triggered. You can see the alarm's configuration, how it calculates warning or critical alarms, and which configuration file you could edit on that node if you want to tweak or disable the alarm to better suit your needs.
Find the bell 🔔 icon in the top navigation to bring up a modal that shows currently raised alarms, all running alarms,
and the alarms log. Here is an example of a raised
system.cpu alarm, followed by the full list and alarm log:
And a static screenshot of the raised CPU alarm:
The alarm itself is named system - cpu, and its context is
system.cpu. Beneath that is an auto-updating badge that
shows the latest value of the chart that triggered the alarm.
With the three icons beneath that and the role designation, you can:
- Scroll to the chart associated with this raised alarm.
- Copy a link to the badge to your clipboard.
- Copy the code to embed the badge onto another web page using an
The table on the right-hand side displays information about the health entity that triggered the alarm, which you can use as a reference to configure alarms.
With the information that appears on Netdata Cloud and the local dashboard about active alarms, you can configure alarms to match your infrastructure's needs or your team's goals.
If you're happy with the pre-configured alarms, skip ahead to enable notifications to use Netdata Cloud's centralized alarm notifications and/or per-node notifications to endpoints like Slack, PagerDuty, Twilio, and more.
