Nginx常用统计命令

Nginx作为一个Web服务器，虽然本身具有非常强大的性能，但是部分场景下会出现请求过慢的情况，这个时候就需要对日志进行分析，查看接口性能分析。虽然有诸如GoAccess、request-log-analyzer等强大的日志分析工具，但是日常还是需要掌握一些进本的Nginx日志分析命令。

1
awk '{print $1}' access.log | sort -n | uniq | wc -l

1
grep "07/July/2021:[08-11]" access.log | awk '{print $1}' | sort -n | uniq | wc -l 

1
awk '{print $1}' access.log | sort -n | uniq -c | sort -nr | head -n {$n}

1
awk '{print $1}' access.log | sort -n | uniq -c | awk '{if($1 > {$n}) print $0}' | sort -rn

1
grep '8.8.8.8' access.log | awk '{print $7}' | sort | uniq -c | sort -rn

1
awk '{print $7}' access.log | sort | uniq -c | sort -rn | head n {$n}

1
grep -v "www.google.com" access.log | awk '{print $7}' | sort | uniq -c | sort -rn | head n {$n}

1
awk '{print $7}' access.log | sort | uniq -c | awk '{if ($1 > {$N}) print $0}' | less 

1
awk '{print $4}' access.log | cut -c 14-21 | sort | uniq -c | sort -nr | head -n {$N}

1
awk '{print $4}' access.log | cut -c 14-18 | sort | uniq -c | sort -nr | head -n {$N}

1
awk '{print $4}' access.log | cut -c 14-15 | sort | uniq -c | sort -nr | head -n {$N}

该命令需要配置Nginx的log_format

1
awk '{if($NF > {$N}) print $7}' access.log | sort | uniq -c | sort -nr | less 

1
awk '{if($NF > {$N} && $7~/{pattern}/) print $7}' | sort | uniq -c | sort -nr | less

1
netstat -tan | grep -i 'established' | grep ':443' | wc -l
