from logA.txt and storing it because this logA.txt is primary file
which has the start and end date of the incident .

Code did as it should have done . I need to change the code according to
my requirement .
My requirement is to start(y) and end timestamp (k) from logA.txt which
the code is getting now correctly then open logC11.txt see the timestamp
nearest to start(y) which its doing now
2018-10-22 10:21:23 and then look for errors(ERR-2 and ERR-3) in the lines
in logC11.txt starting from 2018-10-22 10:21:23 and before the timestamp
(k) ==> here i need help my code is searching for ERR-2 and ERR-3 occurance
in logC11.txt anywhere in the file I want it to search in a specific window
of 2018-10-22 10:21:23 and less than timestamp (k)
so the my present coded has printed the output :
*Install patch1 - wrong solution
This it will print if it executes the following block :
if re.search ( "ERR-2", newst ):
a = re.findall ( "\d\d/\d\d/\d\d\s[012][0-9]:[0-5][0-9]:[0-5][0-9]",
newst )
for i in range ( len ( a ) ):
newtime = datetime.datetime.strptime ( a[i], '%m/%d/%y %H:%M:%S' )
if newtime > y and newtime < k:
print "Install patch1
Now if you see ERR -2 in logC11.txt it occured at 26th april instead it
should have ignored it because the time windows received from logA.txt y
(2018-10-22 10:21:15) and k (2018-10-22 10:21:25) :
LOG file opened at 04/26/18 06:11:52
ERR-2: OS message: No child processes
operation "wait", location "skudmi:prp:6"
In short I would like to only search in lines :
LOG file opened at 10/22/18 10:21:23
ERR-3: patchObjectPossible causes are:"
Trim whitespace same as SQL Loader
How do I acheive this ?
Please advice ,
Thanks in advance,
