问题
I would like to read Windows' event log. I am not sure if it's the best way but I would like to use the pywin32 -> win32evtlog module to do so. First and foremost is it possible to read logs from Windows 7 using this library and if so how to read events associated with applications runs (running an .exe must leave a trace in the event log in windows i guess).
I have managed to find some little example on the net but it's not enough for me and the documentation isn't well written unfortunately ;/
import win32evtlog
hand = win32evtlog.OpenEventLog(None,"Microsoft-Windows-TaskScheduler/Operational")
print win32evtlog.GetNumberOfEventLogRecords(hand)

you can find plenty of demos related to the winapi in your C:\PythonXX\Lib\site-packages\win32\Demos
folder. In this folder you'll find a script named eventLogDemo.py
. There you can see how to use win32evtlog
module. Just start this script with eventLogDemo.py -v
and you will get prints from your Windows event log with logtype Application.
In case you can't find this script:
import win32evtlog
import win32api
import win32con
import win32security # To translate NT Sids to account names.
import win32evtlogutil
def ReadLog(computer, logType="Application", dumpEachRecord = 0):
# read the entire log back.
h=win32evtlog.OpenEventLog(computer, logType)
numRecords = win32evtlog.GetNumberOfEventLogRecords(h)
# print "There are %d records" % numRecords
num=0
while 1:
objects = win32evtlog.ReadEventLog(h, win32evtlog.EVENTLOG_BACKWARDS_READ|win32evtlog.EVENTLOG_SEQUENTIAL_READ, 0)
if not objects:
break
for object in objects:
# get it for testing purposes, but dont print it.
msg = win32evtlogutil.SafeFormatMessage(object, logType)
if object.Sid is not None:
try:
domain, user, typ = win32security.LookupAccountSid(computer, object.Sid)
sidDesc = "%s/%s" % (domain, user)
except win32security.error:
sidDesc = str(object.Sid)
user_desc = "Event associated with user %s" % (sidDesc,)
else:
user_desc = None
if dumpEachRecord:
print "Event record from %r generated at %s" % (object.SourceName, object.TimeGenerated.Format())
if user_desc:
print user_desc
try:
print msg
except UnicodeError:
print "(unicode error printing message: repr() follows...)"
print repr(msg)
num = num + len(objects)
if numRecords == num:
print "Successfully read all", numRecords, "records"
else:
print "Couldn't get all records - reported %d, but found %d" % (numRecords, num)
print "(Note that some other app may have written records while we were running!)"
win32evtlog.CloseEventLog(h)
def usage():
print "Writes an event to the event log."
print "-w : Dont write any test records."
print "-r : Dont read the event log"
print "-c : computerName : Process the log on the specified computer"
print "-v : Verbose"
print "-t : LogType - Use the specified log - default = 'Application'"
def test():
# check if running on Windows NT, if not, display notice and terminate
if win32api.GetVersion() & 0x80000000:
print "This sample only runs on NT"
return
import sys, getopt
opts, args = getopt.getopt(sys.argv[1:], "rwh?c:t:v")
computer = None
do_read = do_write = 1
logType = "Application"
verbose = 0
if len(args)>0:
print "Invalid args"
usage()
return 1
for opt, val in opts:
if opt == '-t':
logType = val
if opt == '-c':
computer = val
if opt in ['-h', '-?']:
usage()
return
if opt=='-r':
do_read = 0
if opt=='-w':
do_write = 0
if opt=='-v':
verbose = verbose + 1
if do_write:
ph=win32api.GetCurrentProcess()
th = win32security.OpenProcessToken(ph,win32con.TOKEN_READ)
my_sid = win32security.GetTokenInformation(th,win32security.TokenUser)[0]
win32evtlogutil.ReportEvent(logType, 2,
strings=["The message text for event 2","Another insert"],
data = "Raw\0Data".encode("ascii"), sid = my_sid)
win32evtlogutil.ReportEvent(logType, 1, eventType=win32evtlog.EVENTLOG_WARNING_TYPE,
strings=["A warning","An even more dire warning"],
data = "Raw\0Data".encode("ascii"), sid = my_sid)
win32evtlogutil.ReportEvent(logType, 1, eventType=win32evtlog.EVENTLOG_INFORMATION_TYPE,
strings=["An info","Too much info"],
data = "Raw\0Data".encode("ascii"), sid = my_sid)
print("Successfully wrote 3 records to the log")
if do_read:
ReadLog(computer, logType, verbose > 0)
if __name__=='__main__':
test()
I hope this script fits your needs
