Performance statistics

Performance Statistics

TempestaFW has a set of performance statistics counters that show various aspects of TempestaFW operation. The counters and their values are self-explanatory. Performance statistics can be shown when TempestaFW is loaded and running.

Below is an example of the command to show the statistics, and the output:

$ cat /proc/tempesta/perfstat

Tempesta health statistics:
        HTTP '404' code : 2

Note that no-cache requests aren't represented neither in Cache hits nor in Cache misses since Tempesta FW doesn't check the cache for such requests.
