The StorageGRID alert system is designed to inform you about operational issues that require your attention. As required, you can also use the legacy alarm system to monitor your system. This section contains the following sub-sections:
StorageGRID includes two systems for informing you about issues.
Alert system
The alert system is designed to be your primary tool for monitoring any issues that might occur in your StorageGRID system. The alert system provides an easy-to-use interface for detecting, evaluating, and resolving issues.
Alerts are triggered at specific severity levels when alert rule conditions evaluate as true. When an alert is triggered, the following actions occur:
-
An alert severity icon is shown on the Dashboard in the Grid Manager, and the count of Current Alerts is incremented.
-
The alert is shown on the Nodes > node > Overview tab.
-
An email notification is sent, assuming you have configured an SMTP server and provided email addresses for the recipients.
-
An Simple Network Management Protocol (SNMP) notification is sent, assuming you have configured the StorageGRID SNMP agent.
Legacy alarm system
The alarm system is supported, but is considered to be a legacy system. Like alerts, alarms are triggered at specific severity levels when attributes reach defined threshold values. However, unlike alerts, many alarms are triggered for events that you can safely ignore, which might result in an excessive number of email or SNMP notifications.
When an alarm is triggered, the following actions occur:
-
The count of legacy alarms on the Dashboard is incremented.
-
The alarm appears on the Support > Alarms (legacy) > Current Alarms page.
-
An email notification is sent, assuming you have configured an SMTP server and configured one or more mailing lists.
-
An SNMP notification might be sent, assuming you have configured the StorageGRID SNMP agent. (SNMP notifications are not sent for all alarms or alarm severities.)
