15 CHAPTER 1 Network Monitoring Overview Network Monitoring Workspace Overview on page 3 Network Monitoring Reports Overview on page 5 Network Monitoring Workspace Overview The Network Monitoring workspace enables you to assess the performance of your network, not only at a point in time, but also over a period of time. This feature enables you to determine trending and diverse other things; for example, whether Service Level Agreements (SLAs) have been violated. Junos Space Network Application Platform has integrated a third-party tool for this purpose, OpenNMS, which is a network management application platform that provides solutions for enterprises and carriers. OpenNMS is installed as part of Platform, which exposes some of the OpenNMS functionality through the Network Monitoring workspace. CAUTION: Although additional OpenNMS functionality can be accessed by customizing its XML files, editing these files can affect the functionality of the Network Monitoring workspace. We recommend that you do not edit these XML files unless you are directed to do so by Juniper Networks. To analyze and aggregate device-level performance data, and to detect device faults, the Network Monitoring workspace uses a collection of data from managed elements. Performance data is collected automatically if the SNMP settings are set properly for a discovered device. Collection View historical performance data by using a graphical monitoring tool that allows customization of the parameters to be displayed and the devices to be monitored Create graphs and charts Create and export reports in PDF and HTML formats 3

16 Network Monitoring Define advanced variables that require calculations for historical performance monitoring Allow raw data to be rolled up into processed data, allowing data to be processed from a more-specific to a less-specific level (for example, data collected at a quarter hourly interval can be rolled into hourly data, hourly data can be rolled into daily data, daily can be rolled into weekly data, and weekly data can be rolled into yearly data) Thresholds Set thresholds for performance data values including specifying warning and error levels Create threshold graphs Generate threshold-crossing alarms that can be displayed or forwarded Faults Receive SNMP traps directly from devices and other enterprise management systems (EMSs) Forward traps to other EMSs Generate and display events and alarms Get basic correlation with alarms; for example, clearing alarms, deduplicating alarms Detect device faults based on data collected from devices You can perform the following tasks from the Network Monitoring workspace: Node List: List all the devices under monitoring (see Viewing the Node List on page 9) Search: Search for devices (see Searching in the Network Monitoring Workspace on page 11) Outages: View unavailable (down) services (see Viewing and Tracking Outages on page 23) Events: View events (see Viewing, Querying, and Acknowledging Events on page 24) Alarms: View alarms (see Viewing and Acknowledging Alarms on page 27) Notifications: Display notices received by users (see Viewing, Configuring, and Searching for Notifications on page 30) Assets: Search asset information and assets inventory (see Tracking and Searching for Assets on page 15) Reports: View reports (see Viewing Reports on page 34) Charts: View charts (see Viewing Charts on page 39) Admin: Perform system administration (see Admin: Configuring Network Monitoring on page 43) 4

17 Chapter 1: Network Monitoring Overview The main Network Monitoring landing page is a dashboard, displaying the most important information about your nodes: Nodes with outages Availability over the last 24 hours Notifications (outstanding notices) On-call schedule Key SNMP customized (KSC) performance reports (if defined and available) In addition, from this page you can do quick searches on nodes and resource graphs. NOTE: Network Monitoring upgrade customization Upgrade from previous releases (12.1 or 12.2) to 12.3 allows a means to preserve the custom configuration that might have been performed on XML files from the backend automatically. For example, Let us assume that you have modified or customized the SNMP poll interval in the collectd-configuration.xml in Junos Space Platform version 12.1 or 12.2, that is, before upgrade to When you upgrade to version 12.3, the upgrade process automatically recognizes the changes made and preserves the changes in OpenNMS database by renaming the XML file. (for example, collectd-configuration.xml.old). You can use these preserved, customized configuration files (in this example, collectd-configuration.xml.old) to update or replace the new configuration files available after the upgrade. Related Documentation Network Monitoring Reports Overview on page 5 Network Monitoring Reports Overview You can generate and view resource graphs, key SNMP customized (KSC) performance reports, KSC node reports, KSC domain reports, database reports, and statistics reports. To access the reports function, select Network Monitoring > Reports. Resource Graphs on page 6 Key SNMP Customized (KSC) Performance Reports, Node Reports, and Domain Reports on page 6 Database Reports on page 6 Statistics Reports on page 6 5

18 Network Monitoring Resource Graphs Resource graphs provide an easy way to represent visually the data collected from managed nodes throughout your network. You can display critical SNMP performance, response time, and so forth. You can narrow your selection of resources by entering a search string in the Name contains box. This invokes a case-insensitive substring match on resource names. Key SNMP Customized (KSC) Performance Reports, Node Reports, and Domain Reports KSC reports enable you to create and view SNMP performance data using prefabricated graph types. The reports provide a great deal of flexibility in time spans and graph types. You can save KSC report configurations so that you can refer to key reports in the future. Node reports show SNMP data for all SNMP interfaces on a node. Domain reports show SNMP data for all SNMP interfaces in a domain. You can load node reports and domain reports into the customizer and save them as a KSC report. You can narrow your selection of resources by entering a search string in the Name contains box. This invokes a case-insensitive substring match on resource names. Database Reports Database reports provide a graphical or numeric view of your service-level metrics for the current month-to-date, previous month, and last 12 months by categories. Statistics Reports Statistics reports provide regularly scheduled statistical reports on collected numerical data (response time, SNMP performance data, and so forth).

To resynchronize your nodes: 1. Select Network Monitoring > Node List > Resync Nodes. 2. Click Confirm. The Resync Nodes Job Information dialog box appears. 3. (Optional) To view details of the resynchronization job, click the job ID displayed in the dialog box. 4. Click OK. The Node List page appears, displaying the resynchronized nodes. Related Documentation Network Monitoring Workspace Overview on page 3 Viewing the Node List on page 9 Turning SNMP Data Collection Off and On on page 10 Viewing Managed Devices Turning SNMP Data Collection Off and On Network performance can be adversely affected by the amount of traffic generated by SNMP data collection. For this reason, SNMP service in Junos Space is not started by default. Junos Space OpenNMS Network Monitoring is always turned on for all devices by default. The ability to turn on data collection is controlled by the Monitor_SNMP surveillance 10

23 Chapter 2: Monitoring Devices and Assets category. Turning on data collection increases the amount of SNMP traffic, however. If the surveillance category is removed from a device, data collection is turned off. To turn SNMP data collection off or on for a device: 1. In the Network Monitoring workspace, display the Node List page and click the node name. The resulting page displays detailed information about the device. For example, you can select Network Monitoring > Node List or you can select Network Monitoring > Search and click All nodes in the Search for Nodes section of the Search page to display the Node List page. 2. In the Surveillance Category Memberships title bar, click Edit. The Edit surveillance categories on node name page appears. 3. Select the Monitor_SNMP category from the Categories On Node list on the right. If this category is not in the list on the right, then SNMP data collection is already turned off. 4. Click Remove between the two lists. The removed category appears in the list of Available Categories on the left. To turn on data collection for selected devices, reverse the process described here. NOTE: OpenNMS performs SNMP data collection by default only on primary interfaces. If you want to change this, instead of manually selecting the interfaces to be monitored from the GUI, you can set data collection for all interfaces by default by modifying the SNMP collection to set the SNMP Storage Flag to all (see Managing SNMP Collections on page 69). For information on the procedure to select other interfaces and the distinction between primary and secondary interfaces, see Configuring SNMP Data Collection per Interface on page 52.
