How to configure the number of method calls to be tracked in the trace details in PHP applications?
The first 1000 methods that exceed the method threshold are tracked by default, after which only the external calls are tracked. You can modify this by changing the zpa.additional_buffer directive in the zpa.ini (Linux) or php.ini (Windows).
Default configuration:
In the zpa.ini (Linux) or php.ini (Windows),
zpa.additional_buffer = 0
For example:
If the value of zpa.additional_buffer is 0, it indicates that the first 1000 methods will be tracked; if it is 2, it indicates that the first 1002 methods will be tracked; and if it is 5, it indicates that the first 1005 methods will be tracked.
If the value of zpa.additional_buffer is 0, it indicates that the first 1000 methods will be tracked; if it is 2, it indicates that the first 1002 methods will be tracked; and if it is 5, it indicates that the first 1005 methods will be tracked.
