Configure alerts for resource usage on Linodes
Akamai offers two alerting systems to notify you when the configured thresholds are crossed in your Linodes:
- Akamai Cloud Pulse alerts. In addition to pre-defined system alerts, Akamai Cloud Pulse lets you create user alerts to customize monitoring and alerting for your Linodes. You can configure custom metrics to be monitored and apply user-generated alerts that will be executed when thresholds you set for those metrics are met. You can create custom notification channels to distribute the alerts, or use system-related alerts that are pre-defined by Akamai for common monitoring events.
- Legacy alerts. These alerts are sent for specific, pre-defined events. When you create a new Linode, various new event alerts are automatically added to it, with default settings. You can later customize these settings by updating your Linode.
Cloud Manager allows you to configure alerts that automatically notify you through email if certain performance thresholds are reached. See the dedicated Akamai Cloud Pulse alerts or Legacy alerts tabs to enable and configure alerts for your Linodes. Legacy and new alerts can be used together.
Akamai Cloud Pulse vs. legacy alertsAs you compare the experience between legacy and Akamai Cloud Pulse alerts, you may notice differences in how some alerts are collected and reported. See the Transition to the new Metrics and Alerts guide for detailed comparison.
Akamai Cloud Pulse alerts for Linodes (Beta)
Akamai Cloud Pulse supports two types of alerts for Linodes:
-
System alerts, which monitor the following service health conditions using the predefined thresholds:
Alert name Description Threshold High CPU Usage Total CPU utilization across all CPU cores, normalized as a percentage of allocated capacity (1-100%).
Note: CPU usage is now normalized across all CPU cores (0-100%) which differs from legacy CPU usage reporting. For example, 4 CPU cores at 50% usage reports 50% CPU usage.
90% High Local Disk I/O Number of input and output operations performed on the Linode's local disk storage per second, which can be used to understand how well the disk can handle concurrent read and write requests 10000 IOPS High Network In Inbound network throughput 10 Mb/s High Network Out Outbound network throughput 10 Mb/s
-
User alerts, which allow you to define custom alerting rules based on Linode metrics and use custom notification channels. For descriptions of the metrics that can be used in Linodes alerts, see View Linode metrics.
To enable and customize Akamai Cloud Pulse alerts:
- Log in to the Cloud Manager and click the Linodes link in the sidebar.
- Select your Linode. The Linode's details page appears.
- Click the Alerts tab. The Alerts panel appears.
- Scroll down to the Alerts NEW section.
- To enable an alert, toggle the appropriate switch next to the Alert Name.
- To configure alerts, click the Manage Alerts button and follow guides in the Alerts category to learn how to view, create, edit, or delete alerts and their notification channels.
System alerts thresholds are not configurable. Create user alerts for thresholds different from the ones predefined by the system. Follow the Create a user alert guide for more information.
- Click Save Alerts to save the alert settings.

If you receive an email threshold alert from the Cloud Manager, do not be alarmed. It does not mean there is anything necessarily wrong with your Linode.
For example, the Linode may be operating above its normal threshold if it is performing intensive tasks such as compiling software (CPU, IO, or both) or if a major website just linked to your blog (increased traffic).
