python写的分析mysql binlog日志工具

上山打老虎

　　因为数据库增删改突然暴增，需要查询是那些表的操作特别频繁，写了一个用来分析bin-log的小工具，找出增删改查的表，并按照操作次数降序排列，以下是代码：

#for mysql5.5 binlog
import os,sys
#python binlog.py binglog-0001 '2013-07-01 00:00:00' '2013-07-02 00:00:00'
def log_w(type,text):
  logfile = "%s.txt" % (type,text)
  #now = time.strftime("%Y-%m-%d %H:%M:%S")
  tt = str(text) + "\n"
  f = open(logfile,'a+')
  f.write(tt)
  f.close()
logname = sys.argv[1]
start_time = sys.argv[2]
end_time = sys.argv[3]
comn = "/usr/bin/mysqlbinlog --start-datetime='%s' --stop-datetime='%s' %s" % (start_time,end_time,logname)
aa=os.popen(comn).readlines()
mylist=[]
for a in aa:
  if ('UPDATE' in a):
      update = ' '.join(a.split()[:2])
      mylist.append(update)
  if ('INSERT INTO' in a):
      update = ' '.join(a.split()[:3]).replace("INTO ","")
      mylist.append(update)
  if ('DELETE from' in a):
      update = ' '.join(a.split()[:3]).replace("from ","")
      mylist.append(update)
mylist.sort()
bb = list(set(mylist))
bb.sort()
cc = []
for item in bb:
    cc.append([mylist.count(item),(item)])
cc.sort()
cc.reverse()
for i in cc:
    print str(i[0])+'\t'+i[1]

执行结果如下：
