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.
...
- Examples
- DNS resolve rate
- Examples
...
- 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 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.
