python3 regular expression.. support to improve

[anna]

Hi All,

I am parsing below logs lines, regex is working, checked on online regex editor(https://regex101.com/), please lets know any suggestion.



Working regex (re.search)
------------------
CAM ID or CAM Id --- (\b\s\:\s)(\d.*?)\b\, --- group(2)

e.g. CAM ID: 19378780 or CAM Id : 3835407
here able to capture 'CAM Id : 3835407' as this end with , and not 'CAM ID: 19378780(' as this ends with '('
sample :- CAM ID: 19378780(A1-VC4-Snk-5 : TU12-Snk-1-2-2 ),

-------------------

Native or native cause --- \s([\w+]{6}\s\w...)\s(\w.*)\b, --- group(2)
e.g. native P.C: LP-EXC, and Native P.C: BIT Failed,

-------------------

system time --- (\d./\d./\d.\s\d.:\d.:\d.) --- group(1)
e.g.[24236:20 04/07/20 13:03:41 InternalExternalAlarmList.cc:55]

-------------------

Port --- \((.*?)\) --- group(1)
here facing issue, sometime string with one opening '(' and end with double '))', and wanted '(' captured in regex.

eg. (XS B:SAM_16 oPort 1-SFP)) or (XS B:SAM_16 oPort 1-SFP ))

-------------------

Nodename --- \b\/([A-Z]{3}?.\w.*?)\b@ --- group(1)
here not able to capture like 'EMS_BG-40_17', how can i capture like EMS~~LSN/EMS_BG-40_17
-------------------

Alarm Status --- (<?[a-zA-Z0-9_ ]+>)\s(.*?\b\s) --- group(2)
Capturing only New or Clear.

e.g. [24236:20 04/07/20 13:03:41 InternalExternalAlarmList.cc:55] > Clear
[1833:22 01/07/20 14:08:25 InternalExternalAlarmList.cc:287] > New

-------------------
