: Four Category types determine the notification type to be sent out for the subscription. Choosing Issue, Change, Job, or System Alert determines the type of notification to be attached to the subscription.
...
Choose from the Time Window dropdown to specify when notifications are sent. Notifications are sent in response to events within a time range. You may choose one time window for any notification. Choices include the following: 24/7, Work Hours, Off Hours, First Shift, Second Shift, Third Shift, and Weekends.
...
Select the Category of notification to be sent (Change, Issue, Job, or System Alert).

Specify notification details depending on the category selected, based on one of the four procedures Defining an Issue Notification, Defining a Change Notification, Defining a Job Notification, or Defining a System Alert Subscription.
NetMRI offers three methods of notification delivery: Email, Syslog, and SNMP trap. All types of notifications support any of the three delivery methods.
Note: In many fields, you can click a single item, or CTRL+click or SHIFT+click to select multiple items.
...
After defining the category and the specifics for the notification type (New Issue, Change, Job, or System Alert), select the notification Method: Email, SNMP Trap, or Syslog. You then define the content for the subscriber's notification.
If you choose Email, click Advanced Settings and follow the steps in the topic Defining Global Notification Email Settings.
If you choose SNMP Trap, enter one or more IP addresses for trap servers into the Server(s) field or accept the configured default. Use commas between each entry if entering more than one destination IP. Save your changes when finished. Also, see Defining Global Notification SNMP Trap Settings.
If you choose Syslog, enter one or more IP addresses for Syslog servers into the Server(s) field or accept the configured default. Use commas between each entry if entering more than one destination IP. For more information, see Defining Global Notification Syslog Settings.
Note: You can define a default Server value for SNMP Trap notifications and Syslog notifications. You specify the server by an IP address or a DNS host name, or more than one, separated by commas. Do so under the Settings icon > Notifications > System Settings and click the Syslog System Setting tab or the SNMP System Settings tab. The values defined here will auto-populate the subscription's Server field. In both cases, the server value is concatenated with the TCP port value.
...
If necessary, edit the To Email Addresses: field, by entering one or more delivery email addresses, who should be the personnel for whom receiving these messages is a priority. (The To User(s) field is not editable by default.)

When being generated and sent to recipients, Notifications can occupy significant system and network resources. For example, creating a new Subscription under the New Issues category with the setting All Issues without paying attention to scheduling or summarization, or a System Alert notification subscription with a large number of selected alert types, may create a substantial stream of notifications to the recipients in the subscription, and needlessly occupy processing and network resources in NetMRI. Avoid creating subscriptions that apply too broadly to various network phenomena or that are sent too frequently to too many recipients. Check for such issues on the System Messages page (Settings icon > Notifications > System Messages). For more information, see System Messages.
