The New Relic Server Monitor's user interface includes "traffic lights" (green, yellow, red, gray) that show the current health of your servers. You can set threshold levels for alerts. You can also identify email addresses to receive notifications about Critical (red) server alerts. (Account email addresses automatically receive Critical server alerts.)
For server problems (CPU, Disk, Memory), at most one alert is generated for an account. If you have several problems with multiple servers at the same time, you will receive one alert when the first problem occurs, and one notice of recovery when all Critical server problems have ended.
The New Relic Server Monitor generates alerts based on excessive resource usage, such as high load average or full disks or memory. You can set threshold levels for Caution (yellow) and Critical (red) alerts for:
New Relic's Server Monitor automatically sends email alerts when system level resources exceed the Critical thresholds. You can also view or filter alerts in the Server Monitor user interface.
Once the resource usage crosses a Critical threshold, there is a waiting period before an email is sent. This helps prevent "false positive" alerts. The waiting time is 15 minutes for CPU or Disk Busy and 5 minutes for Memory or Disk Space Used.
Example: A server's Critical alert threshold for CPU% is 90. New Relic does not send an alert when the server's CPU threshold reaches 90. However, when it goes over 90, New Relic waits 15 minutes to ensure this is not a "false positive" alert. Then, if the CPU threshold is still over 90, New Relic sends the alert notification.
New Relic's default thresholds provide good baseline indicators of serious problems, but you should set your thresholds to meaningful levels for your environment. The highest level you can set is 99%.
New Relic automatically sends email notifications about Critical (red) server alerts to any users who have enabled Alert notifications. (From the New Relic title bar, select (account > User preferences. To identify additional email addresses or other notification options for Critical server alerts: From the New Relic title bar, select (account) > Account settings > Integrations > Alerting notifications.
Server alerts typically are used to send notifications to a mailing list or email-to-SMS gateway, or to send alerts to a designed HipChat or Campfire location. For more information, see Alert Notifications.
Note: You will only receive notification messages about Critical server alerts. However, you can view all alerts and events from the Servers dashboard. This includes Caution alerts (yellow), Critical alerts (red), email notifications, and deployments.
