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
