日常杂记

很早就想写一些shell相关得东西了，平时会用到比较多的shell相关的东西，但是一般都去百度或者google去了，一直觉得不够系统，因此就从日常杂记开始，把日常用到的一些脚本记录下来开始吧。

监控工作通知socket的连接状态：

tail -f /data/micro_servers/logs/inner_api.log | grep 'fail!response' | 
while read msg ;
do python /home/lc/send_wechat.py 'lc@email.com,cy@email.com' '工作通知socket断开,\n请检查服务推送消息是否正常'  $msg;
done

监控是否有消息推送失败

tail -f /data/micro_servers/logs/inner_api.log | grep '推送失败' | while read msg ;
do python /home/lc/send_wechat.py 'lc@email.com,cy@email.com' '工作通知推送失败,\n请关注服务推送消息是否正常'  $msg;
done

发送微信的python脚本

#!/usr/bin/python
# -*- coding: utf-8 -*-

import hashlib
import json
import urllib2
import sys


def getMD5(data):

        hash_md5 = hashlib.md5(data)
        return hash_md5.hexdigest()

# 调用接口发送企业微信消息
def send_wechat(emails, message):
    # emails = ['lc@email.com', 'cy@email.com']
    businessId = 'monitor'
    salt = 'monitor_slat'
    url = 'http://{ip}:{port}/message/inform'
    params = {}
    params['businessId'] = businessId
    params['recipients'] = emails
    params['content'] = message
    params['sign'] = getMD5(businessId + message + salt)

    headers = {'Content-Type': 'application/json'}

    request = urllib2.Request(url=url, data=json.dumps(params), headers=headers)
    response = urllib2.urlopen(request)

    print response.getcode()  # 请求状态，200为成功
    print response.read()  # 返回的body


if __name__ == "__main__":

    if len(sys.argv) < 3:
        print("args error, need more argv like 'xxx@emails.com,xxx@emails.com'")
        sys.exit(-1)

    emails = sys.argv[1].split(",")
    message = sys.argv[2]
    send_wechat(emails, message)

日志统计脚本：

#!/bin/bash
# log statistics 
currentTimeLog=/data//logs/info-$(date "+%Y-%m-%d" -d "1 days ago").log
IFS=$'\n'
cat $currentTimeLog | grep "收到请求:" | grep "null" | awk '{a[$8]=a[$8]+1}END{for (i in a)print i,"请求次数：",a[i]}' | sort -n -t "：" -k2 -r > /home/lc/logStatistics-$(date "+%Y-%m-%d" -d "1 days ago").log
if [ "$?" == 0 ];then
   cat /home/lc/logStatistics-$(date "+%Y-%m-%d" -d "1 days ago").log | mail -s "外部接口访问情况-非网关访问" lc@emails.com lg@emails.com
