================================================================

``ngxtop`` - **real-time** metrics for nginx server (and others)

================================================================



**ngxtop** parses your nginx access log and outputs useful, ``top``-like, metrics of your nginx server.

So you can tell what is happening with your server in real-time.



    ``ngxtop`` is designed to run in a short-period time just like the ``top`` command for troubleshooting and monitoring

    your Nginx server at the moment. If you need a long running monitoring process or storing your webserver stats in external

    monitoring / graphing system, you can try `Luameter `_.



``ngxtop`` tries to determine the correct location and format of nginx access log file by default, so you can just run

``ngxtop`` and having a close look at all requests coming to your nginx server. But it does not limit you to nginx

and the default top view. ``ngxtop`` is flexible enough for you to configure and change most of its behaviours.

You can query for different things, specify your log and format, even parse remote Apache common access log with ease.

See sample usages below for some ideas about what you can do with it.



Installation

------------



::



    pip install ngxtop



Note: ``ngxtop`` is primarily developed and tested with python2 but also supports python3.



Usage

-----



::



    Usage:

        ngxtop [options]

        ngxtop [options] (print|top|avg|sum) 

        ngxtop info



    Options:

        -l , --access-log   access log file to parse.

        -f , --log-format   log format as specify in log_format directive.

        --no-follow  ngxtop default behavior is to ignore current lines in log

                         and only watch for new lines as they are written to the access log.

                         Use this flag to tell ngxtop to process the current content of the access log instead.

        -t , --interval   report interval when running in follow mode [default: 2.0]



        -g , --group-by   group by variable [default: request_path]

        -w , --having   having clause [default: 1]

        -o , --order-by   order of output for default query [default: count]

        -n , --limit   limit the number of records included in report for top command [default: 10]

        -a  ..., --a  ...  add exp (must be aggregation exp: sum, avg, min, max, etc.) into output



        -v, --verbose  more verbose output

        -d, --debug  print every line and parsed record

        -h, --help  print this help message.

        --version  print version information.



        Advanced / experimental options:

        -c , --config   allow ngxtop to parse nginx config file for log format and location.

        -i , --filter   filter in, records satisfied given expression are processed.

        -p , --pre-filter  in-filter expression to check in pre-parsing phase.
