或者
pip install ngxtop
ngxtop使用详解
# ngxtop --helpngxtop - ad-hoc query for nginx access log. Usage: ngxtop [options] ngxtop [options] (print|top|avg|sum) <var> ... ngxtop info ngxtop [options] query <query> ... Options: -l <file>, --access-log <file> 需要分析的访问日志 -f <format>, --log-format <format> log_format指令指定的日志格式 [默认: combined] --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> 根据变量分组 [默认: request_path] -w <var>, --having <expr> having clause [default: 1] -o <var>, --order-by <var> 排序 [默认: count] -n <number>, --limit <number> 显示的条数 [default: 10] -a <exp> ..., --a <exp> ... add exp (must be aggregation exp: sum, avg, min, max, etc.) into output -v, --verbose 更多的输出 -d, --debug print every line and parsed record -h, --help 当前帮助信息. --version 输出版本信息. 高级选项: -c <file>, --config <file> 运行ngxtop解析nginx配置文件 -i <filter-expression>, --filter <filter-expression> filter in, records satisfied given expression are processed. -p <filter-expression>, --pre-filter <filter-expression> in-filter expression to check in pre-parsing phase. 范例: All examples read nginx config file for access log location and format. If you want to specify the access log file and / or log format, use the -f and -a options. "top" like view of nginx requests $ ngxtop 404前十的请求 $ ngxtop top request_path --filter 'status == 404' 总流量前十的请求 $ ngxtop --order-by 'avg(bytes_sent) * count' 访问量前十的ip地址 $ ngxtop --group-by remote_addr 输出400以上状态吗的请求以及请求来源 $ ngxtop -i 'status >= 400' print request status http_referer Average body bytes sent of 200 responses of requested path begin with 'foo': $ ngxtop avg bytes_sent --filter 'status == 200 and request_path.startswith("foo")' 使用common日志格式分析远程服务器Apache访问日志 $ ssh remote tail -f /var/log/apache2/access.log | ngxtop -f common ngxtop实例
ngxtop -c /etc/nginx/nginx.conf
