13 Configure event notifiers and view events HP Scalable NAS generates an event message when an error condition or failure occurs or when the status of the cluster changes. To provide an audit trail of cluster operations, a message is also generated when a user requests and is granted or denied authorization to perform a task. Event messages are logged and can be viewed either with the Cluster Event Viewer provided with the Management Console or with command-line tools. Certain events called Alerts are also displayed on the Management Console. Alerts are tracked by HP Scalable NAS and are automatically cleared when the issue is resolved. HP Scalable NAS also provides event notifier services that can be configured to take a specific action (generate an SNMP trap, send email, or run a script) when certain events occur. Overview Event logs When an event message is generated on a server, HP Scalable NAS logs the message in the cluster log. This log exists on each server and contains messages that were logged on that server and on the other servers in the cluster. The message is also sent to the HP Scalable NAS mxlogd process, which takes these actions: • Sends the message to the event notifier services configured on the server. If the message has been selected to trigger a notifier service, the appropriate action will take place (send an SNMP trap, send email, or run a script). • Sends the message to all servers in the cluster. The servers, including the server where the event occurred, copy the message into their own cluster logs. If the mxlogd process was not running when the event occurred, there will be a delay in transmitting the message to the event notifier services and to the servers in the cluster.
