An alert is an event report that is automatically generated by the system when a specific event occurs. The presence of an alert message indicates that the system has detected an anomaly, and the operation and maintenance personnel need to take appropriate measures to resolve the alarm to avoid serious impact.
Alert capabilities are provided by basic monitoring provided by the cluster or the observability service.
Basic monitoring is only for clusters. When an alert occurs to a cluster, basic monitoring will output the alert information.
In addition to monitoring and alerting the cluster, an observability service can also monitor and alert its associated system services and itself, offering a wider range of alert options. When using the observability service to provide alert services, you must first associate the alert object with the observability service. For specific operations, refer to the Management > Managing observability services > Associating the observability service with a cluster and Associating the observability service with system services sections.
Once the association is complete, the observability service can be used as a unified alert output for multi-cluster and multi-system services.
Arcfra Operation Center (AOC) also provides comprehensive alert rules for clusters and system services. When the resource usage of the virtual machine where the cluster or system service is located reaches the set threshold or a specific event occurs that triggers an alert rule, an alert message will be generated.
You can configure SMTP email alert notifications, SNMP traps or webhook notifications to send alerts to a specified mailbox or third-party client.
