make && make install


Edit your nginx.conf.


    # turn on accounting function
    http_accounting  on;
    server {

        # set accounting_id based on server, use variable
        http_accounting_id  $http_host;
        location / {
            # set accounting_id based on location
            http_accounting_id  accounting_id_str;

Sample syslog output

Apr  8 11:19:46 localhost NgxAccounting: pid:8555|from:1428463159|to:1428463186|accounting_id:default|requests:10|bytes_in:1400|bytes_out:223062|latency_ms:1873|upstream_latency_ms:1873|200:9|302:1

The output contains a list of k/v for the accounting metrics, in the sequence of:

key meaning
pid pid of nginx worker process
from / to metric was collected between these timestamps
accounting_id identify for the accounting unit, you name it with http_accounting_id directive
requests count of total requests processed
bytes_in total bytes receiverd by the server
bytes_out total bytes send out by the server
latency_ms a sum of $request_time, in millisecond
upstream_latency_ms a sum of $upstream_response_time, in millisecond
200 / 302 / 400 / 404 / 500 ... count of requests which response is with http code 200/302/400/404/500, etc
