Server monitor alerting


This information applies to legacy alerting. Learn more about converting to New Relic Alerts.

When an event triggers an alert, the alert summary information appears in your Recent events list. For details about the alert, including history and charts, select the alert's corresponding link. From the details you can also acknowledge that you received the alert notification.

Tip: To filter the Recent events to a specific type of event, select the corresponding icon at the top of the list.

Alert triggers

The New Relic Server monitor generates alerts based on excessive resource usage, such as downtime, or full disks or memory. You can get server alerts for:

Threshold Description
CPU % The CPU usage threshold is the persistent CPU usage rate which considered a potentially unsustainable load. This rate is the average of all CPUs for the server.
Disk IO % Disk IO is the percentage of busy versus idle time for the disks on a server. It is not a measure of throughput.
Memory % The memory usage threshold is the persistent memory usage rate which is considered a potentially unsustainable load.
Fullest disk % Disk capacity is the percentage of the disk capacity being used over time for the fullest disk.
Downtime Downtime is reported when a server has stopped sending data to New Relic for a period of time.

Note: For server monitoring, set Caution threshold conditions lower than Critical conditions. To avoid too many Caution event notifications, set the alert delay time on Caution conditions higher than on Critical conditions.

For server problems (CPU, disk, memory), only one alert is generated at a time for a policy. If you have several problems with multiple servers on the same policy at the same time, you will receive one alert when the first problem occurs, and one notice of recovery after all Critical server problems have ended.

Problems will still appear in the server's Recent Events list, whether or not they generate an alert. The Servers Overview page will flag them with the appropriate color.

The New Relic Server monitor user interface includes status indicators (green, yellow, red, gray) that show the current health of your server resources to determine whether there are additional problems. You can view or filter alerts in the Server Monitor user interface.

Acknowledging alerts

Optional: Acknowledging an alert lets others know the alert has been seen. From the alert details, select Acknowledge alert. This sends an email to acknowledge the event. New Relic records your name in the alert details.
