- 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.
- Examples
- 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 of from Apica Inside Agents which are capable to can collect real-time performance information from multiple in-house sources such as operating
- Operating systems (OS performance data)
- Databases
- Network
- System management frameworks
- NMP
- ARM
- APIs
- Application management modules
