Test Measurement Features

  • Sampling rates up to 100%

    • Store the complete data from every test.

  • Measures in-depth values for each HTTP(S) request

    • DNS resolve time

    • TCP/IP connect time

    • SSL handshake time

    • Request transmit time

    • Time to First Byte of the response header

    • Response header received time

    • Response content received time.

  • Measures internal statistics inside DNS, TCP/IP, SSL, and HTTP layers.

    • Examples

      • DNS resolve rate

      • Abbreviated SSL handshake rate

      • HTTP Keep-Alive efficiency

      • Inner throughput diagram of each received HTTP content response.

  • All measured errors contain snapshots of all of the current HTTP data

    • Request header

    • Request content

    • Response header

    • Response content.

  • All measured errors contain also layer-specific context information

    • Outbound TCP/IP address

    • Outbound TCP/IP port

    • SSL session ID

    • The layer-specific execution step of the failed HTTP(S) request.

      • Example: If an empty web page is returned, you can see clearly if this is caused by a network problem or caused by an overload of the stressed web server.

  • Each measured error contains also a snapshot of

    • The actual values of all user-specific variables and a snapshot-statistic about the activity of all other users at error time.

  • The measurements can be complemented with additional statistics from Apica Inside Agents which can collect real-time performance information from multiple in-house sources

    • Operating systems (OS performance data)

    • Databases

    • Network

    • System management frameworks

      • NMP

      • ARM

      • APIs

    • Application management modules
