About the Reports Tab

To access the Reports tab:

  1. Select Observability > Active Assurance > Measurement Explorer.

    The Measurement Explorer page is displayed.

  2. Click a Measurement-Name.

    The Measurement-Name page is displayed with Reports tab.

You (superusers and network administrators) can use this page to view detailed information about a selected Measurement. The Reports tab provides a centralized view of measurement results and performance data. The reports are generated based on the measurement execution life cycle and plug-in capabilities.

Reports are generated and available only for the Measurements related to the following Plug-ins:

  • Qos Policy Profiling

  • Path MTU Discovery

Report generation is synchronized with the Measurement execution life cycle because Routing Director can produce accurate and complete results only after the Measurement has reached its final state. During execution of Measurement, Routing Director continues to collect data, perform validations, and process plugin‑specific operations. Generating a report before Measurement reaches its final state could lead to incomplete, inconsistent, or misleading information. A Measurement is considered complete when its execution transitions to a Passed, Failed, Error, or Stopped states. The generated reports reflect the performance data, and ensures that the reports represent stable and finalized Measurement results.

Note:

A partial or in-progress Measurements do not generate reports.

Client-based Report Generation

In Active Assurance, every Measurement runs between two Test Agent interfaces. These two endpoints form what is known as a Measurement pair. A Measurement pair consists of:

  • A client (sender) Test Agent interface
  • A server (receiver) Test Agent interface

Both work together to run a QoS Policy Profiling or Path MTU Discovery verification test. The client initiates the request, while the server responds to them.

Routing Director generates report data only from the client’s perspective. This is because the client is the initiator of the test and has full visibility of sent packets, received responses, round‑trip delays, and so on. The server or receiver acts primarily as a responder and does not maintain the complete context required to build a full report.

To view report results, always select the Measurement where the Test Agent interface is configured as the client or sender in the Measurement pair.

Note:

For plug‑ins that do not support report generation, the Measurement Details page displays their results in other tabs such as Metrics, Topology, or PCAP tabs (Observability > Active Assurance > Measurement Explorer > Measurement‑Name).

Tasks You Can Perform

You can perform the following tasks on the Reports tab:

  • View relative time—The relative time displays how long ago the report was generated. You can view the overall relative time of the generated report in HH hours, MM min, SS seconds format.

    Viewing the relative time helps you to understand how relevant the report is. This is useful when you are monitoring active Measurements or comparing results across multiple Measurements.

  • View Measurement details—You can view the following details related to the selected Measurement:

    • Status—Displays the final evaluation state of the selected Measurement, such as Passed, Failed, Stopped or Error. The overall status indicates whether criteria defined in the Measurements are met or not.

    • Duration—Displays the total time taken for the Measurement execution in <M> min <S> sec ago format. The duration defines how long the Measurement ran before reaching the final execution state.

    • Start Time—Displays how long ago the Measurement execution started in <H> hours <M> min <S> sec ago format. This helps you understand when the measurement started relative to the current time.

    • End Time—Displays how long ago the Measurement execution completed in <H> hours <M> min <S> sec ago format. This helps you identify when the measurement was completed relative to the current time.

  • View Measurement direction—You can view the direction of the selected Measurement. The Measurement direction identifies the traffic flow perspective used for Measurement. The direction helps to clarify whether the device acted as the Client or Sender, or Server or Receiver.

  • View configured parameters details—You can view parameters you configured for the Plug-in while configuring a Measurement. You can verify the Plug-in-specific configuration values used during Measurement execution.

  • View Measurement evaluation results—You can view the evaluation results associated with the Measurement. You can identify if there aew any detected deviations from expected behavior, and also view the reason for this behavior.
