# Alert Rules

Alert rules define the conditions that CloudSigma evaluates for database instances.

## View alert rules

Open **OmniFabric > Alerting > Alert Rules**. Use the list to review each rule's status and configured condition.

## Create or update a rule

1. Open **Alert Rules** and select the action to create a rule.
2. Select the resource or condition to monitor.
3. Configure the expression and threshold shown in the form.
4. Select the alert level and notification interval when those options are available.
5. Select one or more recipients from **Contacts**.
6. Review the configuration, save the rule, and make sure it is enabled.

The exact metrics, operators, and notification channels depend on the options shown for your CloudSigma account. Do not copy thresholds from another region or workload without validating them against the monitored instance.

After saving a rule, use [Alert Logs](https://omnifabric.cloudsigma.com/docs/guides/matrixone/alert-logs.html.md) to verify its behavior.
