#`ngxtop` - know what is happenning to your nginx server in real-time.
**ngxtop** parses your nginx access log and outputs useful, `top`-like, metrics of your nginx server.
## Usage
```
Usage:
ngxtop [options]
ngxtop [options] (print|top|avg|sum) <var>
ngxtop info
Options:
-l <file>, --access-log <file> access log file to parse.
-f <format>, --log-format <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 <seconds>, --interval <seconds> report interval when running in follow mode [default: 2.0]
-g <var>, --group-by <var> group by variable [default: request_path]
-w <var>, --having <expr> having clause [default: 1]
-o <var>, --order-by <var> order of output for default query [default: count]
-n <number>, --limit <number> limit the number of records included in report for top command [default: 10]
-a <exp> ..., --a <exp> ... 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.
