This topic describes:

Accessing the Preferences Page

To open the Preferences page, click in the Network Director banner and select Preferences as shown in Figure 1.

Figure 1: Accessing the Preferences PageAccessing the Preferences Page

The Preferences page opens with User Preferences as the default tab.

Choosing Server Time or Local Time

All users can specify whether Network Director displays local time or the server’s time in monitors and reports on the User Preferences tab. The default setting is to display local time. To change the setting to display the server’s time:

  1. In the Preferences page, select Use Server Time from the list.
  2. Click OK to save your changes or click Cancel to close Preferences.

Specifying Search Preferences

Network Director indexes the device inventory data periodically to enable users to perform efficient searches. You can specify a time interval after which Network Director initiates the next indexing on the Search tab. You can also specify to stop indexing while devices are imported into Network Director. If you are running short of system memory, selecting this option helps save some memory and speed up the discovery and import of new devices. By default, this option is selected and the search index update interval is set to 900 seconds.

Enabling Import of Configuration Group Data from Ethernet Design

For Network Director to be able to import configuration group data.

To enable the import of configuration group data:

  1. In the Preferences window, select the Config & Deploy tab.
  2. Select the Enable migration from Ethernet Design check box to enable import of configuration group data. By default this check box is not selected.
  3. Click Save to save and close the preferences.

    For detailed steps on importing configuration group data from Ethernet Design, see Importing Configuration Data from Junos OS Configuration Groups.

Selecting the Approval Mode

Use the Config & Deploy tab of System Preferences to configure the approval mode:

  1. Select the Manual Approval mode if you want an approver to review and approve the changes before they are deployed.

    By default, Auto Approval mode is selected. Use this mode if you want to deploy the configuration changes without a prior approval.

  2. If you select the Manual Approval mode, add one or more approvers’ e-mail addresses to notify the approvers every time a change request is submitted.
  3. Specify the rollback limit, which is the number of change requests that can be rolled back.

    The default value is 50. You can roll back a maximum of 1000 change requests.

  4. Specify the time after which a change request elapses after the time it was created.

    The minimum and maximum number of days that you can specify after which a change request elapses is 1 day and 365 days respectively. The change requests are highlighted in the following colors that indicate their overdue status.

    • Red color—Indicates that the change request is in overdue status.

    • Orange color—Indicates that the change request is due in less than 2 days.

    • Green color—Indicates that the change request is not yet due.

  5. Click OK to save the changes.
Best Practice:

Configuring the approval mode must be a one-time operation. Do not change the approval mode frequently.

To change the approval mode from Auto Approval to Manual Approval, you must either deploy or discard the device configuration changes. You are unable to change the approval mode to Manual Approval, or from Manual Approval to Auto Approval if local changes are in pending deployment state. The message: Do you want to retain the Change Request history? is displayed when you change the approval mode. If you choose to retain the change request history, all the existing change requests are retained by the system. Hence, even if you switch to the Auto Approval mode, you can view the change requests that were created in Manual Approval mode.

Note:

While configuring the Manual Approval mode, you can specify any number of approvers. If you specify more than one approver while configuring the Manual Approval mode, after any approver accepts or rejects a proposed change, the change request is not listed for the other approvers and they cannot approve or reject the same change request.

Setting up Auto-resynchronization Preferences

If you enable auto-resynchronization in Network Director, any configuration changes made on the physical device, including out-of-band CLI commits and change-request updates, automatically trigger resychronization on the device.

To set up auto-resynchronization:

  1. Select the Config & Deploy tab in the Preferences window.
  2. Select the option Purge unassigned system profiles after resynchronizing configuration, which removes unassigned profiles generated by Network Director after resynchronization or deletion of a device.
    Note:

    While upgrading Network Director, the profiles that are in unassigned state are not removed even if you select this option.

  3. Specify the time interval in Auto Resync TriggerWait Interval(sec). Network Director waits for this time interval before triggering auto-resynchronization.

    The default time interval is 120 seconds.

  4. Click OK.

Retaining Network Director Reports

By default, Network Director retains reports for 30 days. However, Network Administrators can change the retention period within the range 0 through 365 days. To change the setting, move the slider right or left on the Report tab of Preferences to the new setting. Click OK to save the setting.

Changing Monitor Mode Settings

The Monitoring tab of Preferences has three tabs under it. These are:

  • Monitoring Settings—Enables you to change the default polling interval for data collection for Monitor mode monitors. You can also disable or reenable the internal processes used for data collection on this sub-tab.

  • Client Session History—Enables you to set the retention period for history records and the frequency that these records are checked for deletion.

  • Data Learning Engine Settings—Enables you to specify the IP address of the Data Learning Engine (DLE) server or servers that supports the flow path analysis and high-frequency statistics features in Network Director.

  • Device Settings—Allows you to enable or disable data collection for one or more devices.

This section describes:

Disabling Data Collection for Monitors

Network Director internally gathers data for monitors by using a set of data collection processes. You can disable these data collectors if they do not pertain to your installation. For example, if you do not use Virtual Chassis, you can disable the data collection processes used for Virtual Chassis.

The data collection processes are divided into the following categories:

  • Client

  • Equipment

  • FM

  • Traffic

  • Virtual

One data collector can be used by multiple monitors. Likewise, some monitors can be supported by multiple data collectors. These data collectors are enabled by default. To ensure proper data collection, if you enable the equipment data collectors, you must also enable the traffic collectors..

To disable or reenable a data collector:

  1. Determine which monitors are used by the data collectors. Use Table 1 to determine the relationship between the data collectors and the monitors.

  3. Click OK and then Yes to verify the change to the configuration.

Enabling and Disabling Collection for Managed Devices

By default all the devices that are discovered and managed by Network Director are enabled for data collection. You can disable or re-enable data collectors across all categories for devices that are managed by Network Director from this tab.

To enable or disable data collectors for devices

  1. Open the Device Settings sub-tab in the Monitor tab.

    All the devices that are managed by Network Director is displayed in the Device Settings section. The last column of the device table indicates the status of data collection as Enabled or Disabled.

  2. Select the devices for which you want to enable or disable data collection and do one of the following:

    • Click Enable to enable data collection for the selected devices.

    • Click Disable to disable data collection for the selected devices.

Specifying Database History Retention

To keep the database manageable, the system periodically checks the age of the records and retires those that have past an expiration date. By default, Network Director ages database records off at 90 days and runs a database cleanup every 6 hours.

Use the Client Session History sub-tab to change the default values:

  1. Select from the lists new values.

    • Age of history records (in days) from 1 to 365 days.

    • Cleanup job frequency (in hours) from 1 through 24 hours.

  2. Click OK to save the changes.

Installing and Configuring Data Learning Engine for Network Director

Data Learning Engine (DLE) enables Network Director to collect and analyze high-frequency statistics and sFlow data for devices that are managed by Network Director. Only the QFX Series devices support the analytics feature that is required for generating high-frequency statistics data. Network Director uses high-frequency statistics data to create network heat maps and to monitor latency in QFX devices and sFlow data to monitor network traffic in EX and QFX devices.

This topic contains the following sections:

Installing DLE

Changing the Severity of Individual Alarms

You can change the severity of the alarms to match your corporate procedures and guidelines. For example, at your company a DoS attack might be considered a critical alarm, while Network Director has a default severity for DoS attacks as a major alarm. Alarms appear on both tabs in the Individual Alarms and Threshold Settings section: Alarm Settings and Threshold Settings.

To change the severity of an alarm:

  1. Select the current severity in the Severity column. A list of the severity levels appear.
  2. Select the new severity level for the alarm.
  3. Click OK and Yes to confirm the change to the severity setting.

    To configure alarm notifications, see Configuring Individual Alarm Notifications.

Configuring Threshold Alarms

Threshold alarms are alarms that are generated when a monitored value crosses the configured threshold. They provide enhanced visibility into potential issues on the network. You configure and manage threshold alarms the same way as other alarms. You also have the option of setting the threshold level of individual threshold alarms.

To edit the threshold of threshlod alarms:

  1. Select the Threshold Settings tab in the Individual Alarms and Threshold settings section of the Fault tab.
  2. Click Edit Settings in the Threshold Settings column of the alarm threshold you want to edit.
  3. Set the threshold in the window that opens.
  4. Click Save to save the new threshold.

    To configure alarm notifications, see Configuring Individual Alarm Notifications.

Configuring Individual Alarm Notifications

You can configure e-mail notifications to be sent when an individual alarm is generated. When you enable notification for an alarm, the notifications are sent to the e-mail addresses configured for the alarm and the addresses configured for global alarm notifications. Alarms appear on both tabs in the Individual Alarms and Threshold Settings section: Alarm Settings and Threshold Settings.

To configure e-mail notification for an alarm name:

  1. Select the check box in the alarm’s Notification column.

    If you later want to disable notification for the alarm, clear the check box.

  2. Click Edit Notification in the Notification column. The Alarm Notification Details window opens.
  3. Type one or more e-mail addresses in the Notification Email Addresses box. Separate addresses with a comma (,).

    You can later edit the addresses to send notifications to different addresses.

  4. (Optional) Type a comment in the Comments box. This comment is included in the e-mail notification message.
  5. Click Save.
