- Click the Settings icon > Notifications > Subscriptions to begin creating notifications.
Click the Add Notification button. The Add Notification dialog appears. Here, you select the various elements that comprise a notification, including the notification Category; a Time Window; and other more - specific information for each notification type.
Note title Note 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.
...
4. Select the Category of notification to be sent (Change, Issue, Job, or System Alert).
5. 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.
In many fields, you can click a single item, or CTRL+click or SHIFT+click to select multiple items.
6. After defining the category and the specifics for the notification type (New Issue, Change, Job, or System Alert), select the notification Method: Email, SNMP 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.

The following topics describe the four notification types in greater detail.
...
New Issue notifications let administrators know when problems are detected by NetMRI during network data collection. (For more information about Issues, see Evaluating Issues in NetMRI.)
To define a New Issue notification, do the following:
- Click Settings icon –> Notifications –> Subscriptions to begin creating notifications.
- Click Add Notification.
- From the Category dropdown, choose Issue.
- Choose the Time Window over which the notification subscription will operate.
- If necessary, enable the Send Clearing Notifications option in the upper right corner. If activated, a notification is sent when an issue covered by the notification is cleared.
- Choose the Severity: Info, Warning or Error.
Info, Warning and Error are the three standard NetMRI severity classifications. - Choose the Issues to trigger the notification. Select multiple issues by holding the Ctrl key or the Shift key while selecting. Selecting All Issues automatically enables any issues to generate a notification.
- Choose one or more Device Groups for triggering notifications of specified issues.
- Choose one or more Interface Groups for triggering notifications of specified issues.
- Choose the Method by which admins will receive Job notifications: Email, SNMP Trap or by Syslog.
For Email: select the To Users to receive the notification. (Administrators can send notifications to anyone. Non-administrative users can send notifications only to themselves.)
Specify additional To email address(es) if needed. Separate multiple e-mail addresses by commas.
Note: Email notifications also require the correct SMTP servers to be configured in the appliance to support sending the notifications to their destinations. See the Setting Notification Defaults topic for more information.
If needed, click Edit Schedule to specify a schedule for the summary e-mail notification;
The Summarize checkbox sends a digest email of the system alerts for the selected category, providing a way to reduce email quantities sent to administrators’ inboxes. Deactivate the Summarize checkbox to receive all notifications for each individual system alert.

Change notifications inform NetMRI administrators about configuration changes and device status changes that take place on the network.
NetMRI also provides the ability to prevent excessive Config Change notifications based on changes in volatile or transient configuration data changes that bear little or no significance in device operation or device management, such as admin password changes.
Filtering of such notifications occurs automatically without user intervention. You can also use an Advanced Setting to specify a list of user accounts that NetMRI can “ignore” when those users commit configuration changes that would otherwise be reported. (For information, see Filtering Change Notifications from User Accounts below.)
To define a Change notification, do the following:
- Click Settings icon –> Notifications –> Subscriptions to begin creating notifications.
- Click Add Notification.
- From the Category dropdown, choose Change.
- In the Change Types section, select one out of six choices (or Ctrl+click to select more than one):
- All: all types;
- Admin: changes to the actual configuration files on the device(s);
- External: changes to the devices in the notification that are carried out by an external source, such as a change to the DNS record on a device;
- Hardware: Notification of a change in a device’s hardware configuration, such as the removal or addition of a network module or line card;
- Software: notification of a change in the device’s software/OS version.
5. Choose the Method by which admins will receive Job notifications: Email, SNMP Trap, or by Syslog.
- For Email: select the To Users to receive the notification. (An administrator can send notifications to anyone. Non-administrative users can send notifications only to themselves.)
- Specify additional To email address(es) if needed. Separate multiple e-mail addresses by commas.
Note: Email notifications also require the correct SMTP servers to be configured in the appliance to support sending the notifications to their destinations. For information, see Setting Notification Defaults.
- If necessary, click Edit Schedule to specify a schedule for the summary email notification, or deactivate the Summarize checkbox to receive all notifications for each individual system alert.
The Summarize checkbox sends a digest email of the system alerts for the selected category, providing a way to reduce email quantities sent to administrators’ inboxes. - To manage notification email settings in more detail: click the Advanced Settings button to override default settings for sender information, message type, message subject, message content, and details. For information, see Notification Content and Formatting.
- For SNMP Trap: override the default Server(s) by entering a new IP address.
- For Syslog: If necessary, override the default Server(s) and Message. See the Notification Content and Formatting topic for information about placeholder variables.
- If necessary, click Edit Schedule to specify a schedule for the summary email notification, or deactivate the Summarize checkbox to receive all notifications for each individual system alert.

You can filter and ignore configuration change notifications executed by automated systems operating with network infrastructure, or filter change notifications resulting from executions of a NetMRI Automated Change Management (ACM) process. These processes often use a designated login. NetMRI can use these logins as signals to filter out any and all Change Notifications while the job executes. This enables the appliance to ignore such messages for Configuration Management purposes.
Network devices affected by such tasks must be configured to send Syslog messages to the NetMRI appliance.
You configure an Advanced Setting to complete this configuration:
- Click Settings icon –> General Settings –> Advanced Settings.
- In the Configuration Management category, Action Edit for the Config Syslog Change Filter Usernames setting.
- Enter a comma-delimited list of user names for the automated systems or admin user accounts, such as follows:
rsmith,hpnode_1,hpnode_2,cab_admin,grey_goose - Click OK when complete.
...

- Click Settings icon –> Notifications –> Subscriptions to begin creating notifications.
- Click Add Notification.
- From the Category dropdown, choose Job.
- Choose the Job Status: All, Requiring Approval, Approved, or Completed.
- Choose one or more Device Groups that will trigger notifications of the specified issues.
- Choose the Method by which admins will receive Job notifications: Email, SNMP Trap, or by Syslog.
