使用Python记录跟踪守护进程

我们有一个遗留的

C

编写的程序，可以将日志输出到文本文件，并且该程序能够每天旋转日志

e、 g

现在我想编写一个python守护进程，跟踪日志并将其注入DB，我的问题是

用Python跟踪文件的推荐方法是什么<代码>扭曲的或

Pyinotify

如何处理守护进程停止并且需要恢复日志跟踪的情况？我应该将偏移量存储在另一个文件中吗

谢谢。

我也遇到过类似的问题。 我的做法是：

import io
import time

def checklog(fs,logfile):
    trytimes = 10
    line = ''
    while line == '':
        time.sleep(1)
        line = fs.readline().replace('\n','')
        trytimes = trytimes - 1
        while trytimes == 0 and line == '':
            try:
                fs = io.open(logfile,'rb')
                fs.seek(0,2)
                trytimes = 10
                break
            except:
                time.sleep(10)
    return line,fs


logfile="app.log"
fs = io.open(logfile,'rb')
fs.seek(0,2)# seek to tail of the logfile
while True:
    line = fs.readline().replace('\n','')
    while line == '':
        line,fs = checklog(fs,logfile)
        #do something for line;

希望这有帮助

import io
import time

def checklog(fs,logfile):
    trytimes = 10
    line = ''
    while line == '':
        time.sleep(1)
        line = fs.readline().replace('\n','')
        trytimes = trytimes - 1
        while trytimes == 0 and line == '':
            try:
                fs = io.open(logfile,'rb')
                fs.seek(0,2)
                trytimes = 10
                break
            except:
                time.sleep(10)
    return line,fs


logfile="app.log"
fs = io.open(logfile,'rb')
fs.seek(0,2)# seek to tail of the logfile
while True:
    line = fs.readline().replace('\n','')
    while line == '':
        line,fs = checklog(fs,logfile)
        #do something for line;
