    The Packet Forwarder is used to capture and forward hits to a cloud-based DNCA that is operating on a virtual machine.
  - SSL Keys
    For decrypting transmissions by using the SSL protocol, the Unica Discover Network Capture Application must be provided the SSL keys in use in the transaction stream.
  - Performance Measurement
    Performance measurement provides details on the Network Capture software performance and timestamp measurements.
    - Timestamp overview
      You can use timestamp values to analyze performance of the DNCA.
    - Example timestamps in the request
      The following example values is displayed in the request after the DNCA generates its timestamps.
      - Timestamp Definitions and Values in the Request
        The following table provides an explanation for each of the values in the [timestamp] section of the request:
      - Calculating Times from Timestamps
        You can measure the performance by calculating the times from the timestamp values.
    - Factors Affecting Timestamp Values
      The following factors must be considered when evaluating timestamps.
    - Testing Discover Processing Performance
      You can use the following test to check how quickly Discover is processing hits. In an ideal system, the length of time between the DNCA capturing a hit and it appearing in the Short Term Canister is a few seconds.
    - Reporting
      Reports that are based on timestamp information that is captured and computed by Discover can be configured and reviewed through the Discover Portal.
  - Configuring DNCA on Red Hat Enterprise Linux™ (RHEL)
    The following sections contain important information for configuring DNCA in a Red Hat Enterprise Linux™ environment:
  - DNCA monitoring
    You can monitor the passive capturing to diagnose performance issues.
  - Overview of DNCA maintenance
    The maintenance utility performs routine maintenance and logging tasks for Discover DNCA. You can use the utility to help maintain the ability of the DNCA to perform DNCA.
  - DNCA frequently asked questions (FAQ)
    The following content contains frequently asked questions or scenarios that can be used to help isolate or fix an issue with your Network Capture Application.
