20 Network Monitoring 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. NOTE: Junos Space Release 13.3 and later supports SNMP monitoring of devices using SNMP v1 and SNMPv2c. CAUTION: Although additional network monitoring 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 grant a Junos Space user full privileges to access and perform tasks from the Network Monitoring workspace, the user must be assigned the FMPM Manager role. To grant a Junos Space user read-only access to the Network Monitoring workspace, the user must be assigned the FMPM Read Only User role. The Network Monitoring workspace supports the following three types of users: Administrator role: A user assigned the FMPM Manager role and with access to Global domain can view and administer all devices in the Network monitoring workspace, including all devices that exist in other sub-domains. Regular user role: A user assigned the FMPM Manager role but without access to global domain can only view and administer devices in their selected domain. This type of user can also acknowledge and clear alarms. Read only user role: A user assigned the FMPM Read Only User role (or a customized role with FMPM access capability except admin tab) in Junos Space. This type of user can only view devices in the selected domain, but cannot access the Network Monitoring > Admin workspace and cannot acknowledge or clear alarms. When a remote user (with the FMPM manager role) logs in from the Junos Space user interface, Junos Space authenticates the user from the remote authentication server as follows: If the remote authentication is successful, Junos Space uses the user s login credentials to authenticate with the network monitoring server and either creates or updates the network monitoring local user. If the remote authentication fails and the user previously existed on the network monitoring server, Junos Space removes the network monitoring local user. To analyze and aggregate device-level performance data, and to detect device faults, 4

21 Chapter 1: Network Monitoring Overview 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. The following performance data is collected: 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. 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 and 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 17). Search: Search for devices (see Searching in the Network Monitoring Workspace on page 20). Outages: View unavailable (down) services (see Viewing and Tracking Outages on page 35). Events: View events (see Viewing and Managing Events on page 36). Alarms: View alarms (see Viewing and Managing Alarms on page 41). 5

22 Network Monitoring Notifications: Display notices received by users (see Viewing, Configuring, and Searching for Notifications on page 47). Assets: Search asset information and assets inventory (see Tracking and Searching for Assets on page 24). Reports: View reports (see Viewing Reports on page 50). Charts: View charts (see Viewing Charts on page 55). Topology: View nodes in the network topology and the events and alarms associated with the nodes (see Working with Topology on page 25). Admin: Perform system administration (see Admin: Configuring Network Monitoring on page 63). 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: During the Network Monitoring upgrade process, the modified configuration files are automatically merged. However, if the automatic merge fails, you must manually merge the files that could not be merged by following the procedure explained in the Updating Network Monitoring After Upgrading the Junos Space Network Management Platform on page 65 topic When you upgrade from Release 13.1 or Release 13.3 to Release 14.1, the linkd-configuration.xml file is renamed to linkd-configuration.xml.old.bak, and the enlinkd-configuration.xml file is added.

23 Chapter 1: Network Monitoring Overview 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 7 Key SNMP Customized Performance Reports, Node Reports, and Domain Reports on page 7 Database Reports on page 7 Statistics Reports on page 7 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 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).

25 CHAPTER 2 Alarm Notification Overview Alarm Notification Configuration Overview on page 9 Alarm Notification Configuration Overview By default, the alarms generated by managed devices in the Junos Space platform are sent to the network monitoring functionality. To enable alarm notification for supported Junos Space applications, you can configure the alarmnotificationconf.xml file to specify the alarm notifications that designated Junos Space applications should receive. The applications will receive only those alarms that you configure in the alarmnotificationconf.xml file and that match the specified filter criteria. You can configure basic and advanced filters so that any alarms that match the configured filtering conditions are forwarded to the designated applications. Basic Filtering on page 9 Guidelines for Configuring Alarm Notifications on page 10 Advanced Filtering on page 10 Basic Filtering You configure a basic filter to filter alarms based on the Unique Event Identifier (UEI), device family, and severity. At minimum, you must configure a UEI filter. Filtering by device family, severity, or both, is optional. To configure a basic filter for alarm notification, at minimum, you must configure the following notification tags in the alarmnotificationconf.xml file, which must reside in the /opt/opennms/etc/alarm-notification directory: Notification name UEI of the alarm to be notified The script to be executed for the configured UEI You can also configure the following tags in the alarmnotificationconf.xml file: Severity Supported severity values are Indeterminate, Cleared, Normal, Warning, Minor, Major, and Critical. 9
