Alerts can be configured for and assigned to devices, performance monitors, passive monitors, and active monitors. Alerts for performance monitors are configured and assigned in the Alert Center. Alerts for devices, active, and passive monitors are configured in the Action Library and are assigned either during the configuration process or from the Device Properties dialog.
In addition to alerts for devices and monitors, you can configure alerts for WhatsUp Gold system aspects, and the Flow Monitor and Wireless plug-ins. These alerts are configured and enabled in the Alert Center.
For example, Nick, the network administrator from Step 1, has created a Domain Service (DNS) active monitor for his web server, and an SNMP Trap passive monitor for his mail server. He has also enabled the Disk Utilization performance monitor for his four storage servers.
For the DNS active monitor assigned to the web server, Nick wants to be notified immediately if the DNS port is unavailable. An SMS Direct message sent to his cell phone will alert him immediately following the monitor's issuance of a down state.
For the SNMP Trap passive monitor assigned to the mail server, Nick wants to be alerted if Authentication Failure traps are observed by the SNMP Listener.
For the Disk Utilization performance monitors enabled for the 4 storage servers, Nick creates thresholds in Alert Center and configures a Notification Policy to alert him when the servers reach certain levels of fullness.
Nick also assigns an SMS Direct action to each of the storage servers so that he is notified immediately if a device goes down, causing the information stored on the servers to be unavailable to colleagues and software customers.
Each of the example procedures are outlined in the following sections.
