User Experience Score

User-Defined Dashboard F.A.Q.

What is a Network Performance Dashboard?

A network performance dashboard is a report populated with widgets, and these widgets show the information collected by your data sources.

Your reports—your dashboards—are populated with one or many widgets. The data shown by widgets in your dashboards belongs to Observer. To make use of dashboards, Observer must be collecting network trending data and be a data source to Apex. Without trending data, Apex will not have any data for the widgets in a dashboard.

Dashboards that are pre-made by VIAVI are available to you as system dashboards. System dashboards are identical in function to dashboards you create on your own, but they cannot be modified. Additionally, system dashboards provide broad information and are useful for high-level analytics. A temporary filter can be used while viewing system dashboards, but a permanent filter cannot be added.

Any dashboard can have an always-on filter written into its properties. Dashboard filters force every widget in a dashboard to display only information that meets the filter. For example, you can filter a dashboard so that its widgets show statistics from a specific subnet only. Or you can filter a dashboard to search for a telephone number used in a VoIP conversation.

A dashboard filter can be applied to the design of the dashboard itself (always-filtered), applied during viewing of the dashboard (temporary), or applied as a combination of the two.

Each newly created dashboard is considered a user dashboard. User dashboards are unique to the user that logged in to Apex and created it, and it can only be viewed and modified by that user. To share a user dashboard with other Apex users, the creator must promote the dashboard. A promoted dashboard becomes a site dashboard that is viewable by other users. A promoted dashboard cannot be demoted.

This means you can promote a user dashboard to a site dashboard without promoting the underlying user widgets—if any exist. This protects your personal user widgets from being altered and changed by others. If you want to share a dashboard with others (by promotion) and also allow changes to those widgets, the widgets must be promoted to site widgets.

As long as you are viewing a site or system dashboard—user dashboards are not applicable—your current view of the dashboard can be summarized into a shareable URL. Whoever clicks the URL you share can see the dashboard how it appeared to you. Choices you have made like the reporting period and any temporary dashboard filters are retained by the URL. You can use this sharing feature in your instant messages, emails, or other documents.

Key Features Overview

  • Apex Available as an Amazon Machine Image (AMI)

    Apex can now be procured on the Amazon Marketplace website as an AMI for simple, efficient cloud deployment.

  • Certificate Management

    Automated analysis designed to prevent SSL/TLS certificate expirations and insecure sessions from going unnoticed. Provides security and network engineers with real-time analysis, reporting, and notifications, keeping teams one step ahead of certificate expirations. Allows for easy identification of servers publishing insecure sessions. Enables teams to swiftly retire outdated or insecure protocols, improving the overall security posture. Identifying and remediating certificate-related issues, helps to prevent potential outages and ensure a seamless user experience.

  • Unified Communications (UC)

    Purpose-built dashboards combined with highly efficient workflows provide actionable insights for global, site-specific, and single-call UC visibility. Interactive Call Details visualizations show the paths calls take through the network infrastructure, pinpointing exactly where and why quality degradation occurs. One-click access to relevant packet data is also provided, ensuring VoIP and UC experts have all the information they need to monitor call quality and perform efficient troubleshooting.

  • End-User Experience Scoring

    Machine learning powered end-user experience (EUE) scoring for every every transaction with intelligently rolled-up values at the dashboard site level. Scores are color-coded and range from 0 to 10 with the corresponding problem domain highlighted. EUE scorecards show a clear display of the overall score, along with the individual scores for the contributing domains: Network, Client, Server, and Application. For EUE values with score deductions across multiple domains, you can easily identify and prioritize the issues that matter most. When a single domain contains multiple score deductions, each issue is listed along with its corresponding deduction, making it clear what is contributing the most to performance degradations.

  • Custom Dashboards and Streamlined Workflows

    Customizable dashboards provide network observability of IT service health at the regional, country, city, data center levels, or functional level. When combined with end user experience scoring, IT teams can gain instant world-wide situational awareness of all resources and then, when required quickly drill down to an individual user for rapid problem resolution.

  • On-Demand Multi-Tier Application Intelligence

    On-Demand Multi-Tier Application Intelligence

    On-demand application dependency mapping offers fast discovery of app interdependencies. Maps are built automatically to display complex relationships with simple clarity. This allows users to determine worst connections, app tiers, and network delay threshold deviations, while sorting all connections by status; critical, marginal, and acceptable.

  • Network Security Forensics

    Not every performance issue can be solved without going back-in-time to analyze the underlying root cause of the problem. Likewise, given the never-ending series of cybersecurity breach announcements worldwide, it’s clear even the most robust IT security defense strategy with solutions such as firewalls, IDS/IPS, and SIEMs are necessary but no longer enough to protect critical resources—especially the organization’s crown jewels. That’s why Apex provides network forensics based on traffic and enriched flow to provide in-depth visibility past network activity.

  • Gigaflow IP Viewer

    Intuitive Visualizations with IP Viewer

    By compiling Layer 2 to Layer 3 insights into a single enriched flow record, Observer can produce unique, interactive visualizations that illustrate the relationships between User, IP, MAC, and application usage in the network. A NetOps or SecOps user can simply enter a name enter in a username and immediately find all devices, interfaces, and applications associated with it. Finding out what is connected and who is communicating across your network has never been easier.

  • Advanced Deep Packet Inspection (DPI)

    Gaining in-depth insights into network traffic can be challenging. The added visibility provided by DPI allows network engineers to easily identify traffic running on non-standard ports, recognize and classify various traffic types, and take a deeper look into protocols like HTTP and HTTPS.

    DPI capabilities provide answers to commonly asked questions:

    • What is this unidentified traffic and what application, or service is it associated with?
    • What is all this HTTP/HTTPS traffic – Is it traffic I want on my network?
    • Is non-business traffic causing congestion and impacting performance?


Observer Apex collects and aggregates data from Observer GigaStor, Observer GigaStor M, Observer GigaFlow to achieve enterprise-wide network observabilityand security visibility for NetOps and SecOps teams. By intelligently combining packet information, metadata, and enriched flow records, Apex delivers centralized management of end-user experience scoring, performance, and cybersecurity intelligence.
