In-Depth Test Measurements

  • 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.

  • 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

    • 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 of Apica Inside Agents which are capable to collect real-time performance information from multiple in-house sources such as operating systems (OS performance data), databases, network, and system management frameworks, SNMP, ARM APIs and application management modules.
