    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, 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:

    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 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.
