定时统计每天nginx error的脚本

目的

了解每天nginx errorlog里面出现的错误类型和次数,和zabbix的报警核对,确保报警无漏报或者误报

执行方式

crontab定时执行

0 10 * * * /root/total_nginx_error.sh

脚本介绍

脚本内容

cat total_nginx_error.sh
#!/bin/sh
error_log=/var/log/nginx/error.log-`date +%Y%m%d`
reciever="somename@likeyou.com"
key1="upstream prematurely closed connection while reading upstream"
get_error_upstream() {
  grep error $error_log |\
    awk -F, '{print $1}'  |\
    awk -F: '{print $4,$5}' |\
    awk '{for(i=2;i<=NF;i++){if(i==NF)printf "%s%1c\n" ,$i," " ;else printf "%s%1c" ,$i, " " }}' |\
    awk '{name[$0]=$0;cnt[$0]++}END{for(i in name)print cnt[i],name[i]}' |sort -nr -k 1
}

send_notification() {

  get_error_upstream  |mail -s "Nginx errors checklist `date +%Y%m%d`" $reciever

}
send_notification

发邮件需要安装的软件及配置

需要安装sendmail

安装略

需要有可以发邮件的邮箱,并在/etc/mail.rc 作如下类似配置

# Set smtp server of  alert
set bsdcompat
set from=opsbot@likeyou.com             #修改为自己的邮箱账户

set smtp="smtp.likeyou.com"            #修改为自己的邮箱账户
set smtp-auth-user=somename@likeyou.com  #修改为自己的邮箱账户
set smtp-auth-password="somewords"

set smtp-auth=login

然后每天可以收到错误统计,通过分析帮助改进运维监控
