    Viewing the Administration Statistics

    The Administration statistics page displays the following information: graphical details about system health; a system health report on the Junos Space fabric, and JBoss and MySQL database processes; and a list of system alert messages that were received in the last 30 days.

    To access the Administration statistics page:

    1. On the Junos Space Network Management Platform UI, select Administration.

      The Administration statistics page appears, displaying three boxes titled System Health, System Health Report, and System Alert Messages in Last 30 Days.

    This topic contains the following sections:

    Viewing System Health Information

    The System Health section displays three charts related to system health. For more information about these charts, see Viewing the Junos Space Platform Dashboard.

    Viewing the System Health Report

    Starting with Junos Space Network Management Platform Release 15.2R1, you can view records about the health and performance of the Junos Space nodes in your Junos Space setup and the processes on these nodes in a system health report. The health and performance data collected from the nodes is displayed in a table. The health and performance data is categorized by parameters related to the Junos Space fabric and the JBoss and MySQL processes.

    The Process column in the table displays the process and the Parameter column displays the parameter of the process that is evaluated. The Status column displays the status of the parameter. No is displayed in green if the parameter is within the configured threshold. Yes is displayed in red to indicate that the process has exceeded the threshold and must be corrected by the administrator. The Status column displays Yes in red until the issue is fixed. A user assigned with appropriate privileges can click the Click link corresponding to the process in the More Details column to view more details.

    Table 1 lists the processes, parameters, descriptions, and data displayed when you click the links in the More Details column, and the type of nodes from which the parameter collects the system health details.

    You can configure appropriate threshold values and time intervals to collect health and performance data and update the System Health Report. These thresholds are applicable to all relevant nodes in the Junos Space fabric. For more information about configuring thresholds and time intervals, see the Health Monitoring section in the Modifying Junos Space Network Management Platform Settings topic.

    Note: You must be assigned the privileges of a Super Administrator, System Administrator, or any role with appropriate privileges to view more details by clicking the link related to the process and parameter.

    To alert selected users and fix issues when the parameter exceeds the threshold, you can add users to the Email Listeners list to receive notifications. Users receive e-mail alerts when the health and performance of the Junos Space nodes are below the threshold and the Status column displays Yes in red. For more information about adding users, see Adding Users to the Email Listeners List.

    Note: The Multi-Master Detected and MySQL in out of sync state parameters display N/A in a single-node Junos Space setup.

    Note: The Fabric node in the DOWN state detected parameter and the JGroups membership issue detected parameter are displayed only in a Junos Space setup with multiple JBoss nodes.
