The Alerts page allows you to toggle CockroachDB Cloud alerts, send test alerts, and view the email recipients and alert history for your CockroachDB Cloud Organization. To view the Alerts page, log in and click Alerts.
The Alerts page is accessible on CockroachDB Dedicated clusters. For CockroachDB Serverless clusters, all Org Administrators will automatically receive email alerts when your cluster reaches 50%, 75%, and 100% of your resource limits.
If alerts are enabled, CockroachDB Cloud will send alerts to specified email recipients when the following usage metrics are detected:
Storage Utilization:
- Cluster-wide available disk capacity is 20% or less.
- Node-level available disk capacity is 10% or less.
CPU Utilization:
- Cluster-wide CPU usage is 80% or greater on average for at least 60 minutes.
- Node-level CPU usage is 90% or greater on average for at least 90 minutes.
Memory Utilization:
- Cluster-wide available memory is 20% or less on average for at least 60 minutes.
- Node-level available memory is 10% or less on average for at least 90 minutes.
CMEK:
- Cluster node unable to start due to CMEK key access failure.
- Encrypted backup failed due to CMEK key access failure.
If you receive an alert repeatedly, you may need to optimize your workload or scale your CockroachDB Cloud cluster.
Org Administrators will also receive email alerts when your cluster undergoes an automatic patch version upgrade.
When scaling your cluster, we recommend first scaling VMs to include more than 2 vCPUs each. If this doesn't sufficiently improve performance, then add more nodes.
Configure alerts
To enable alerts:
- Under Configure CockroachDB Cloud alerts, toggle the Alerts are on switch.
- Under Add Email Recipients, add at least one email address and click Add.
Note that alerts are enabled for all clusters in your Organization. To filter alerts on specific clusters, you can use an email alias to send alerts to a monitoring tool such as Alertmanager or PagerDuty.
To send a test alert:
- Under Send test email, select a cluster and an alert type.
- Add at least one email address and click Add.
- Click Send test email.
Repeated alerts
If the condition triggering an alert does not change, the alert will repeat at a specific cadence:
Storage Utilization:
- Cluster-wide alerts: every 60 minutes
- Node-level alerts: every 60 minutes
CPU Utilization:
- Cluster-wide alerts: every 60 minutes
- Node-level alerts: every 90 minutes
Memory Utilization:
- Cluster-wide alerts: every 60 minutes
- Node-level alerts: every 90 minutes
