As the core has almost all features implemented that the datalog plugin features I wanted to implement the one feature missing: using placeholders in the filename. I was successful so far with this code, however - when rotating the file it would be necessary to write into a newly created file with the same placeholder but new values instead of the old one.
e.g.: filename: ./var/log/test{year}_{hour}.csv
class ShngTimedRotatingFileHandler(logging.handlers.TimedRotatingFileHandler):
"""
TimedRotatingFilehandler with a different naming scheme for rotated files
"""
def __init__(self, filename, when='MIDNIGHT', interval=0, backupCount=0, encoding=None, delay=False, utc=False):
self._originalname = os.path.basename(filename)
super().__init__(self.parseFilename(filename), when, interval, backupCount, encoding, delay, utc)
def parseFilename(self, filename):
year = datetime.datetime.now().strftime("%Y")
month = datetime.datetime.now().strftime("%m")
day = datetime.datetime.now().strftime("%d")
hour = datetime.datetime.now().strftime("%H")
minute = datetime.datetime.now().strftime("%M")
stamp = datetime.datetime.now().timestamp()
try:
return eval(f"f'{filename}'")
except Exception:
return filename
def doRollover(self):
prs = self.parseFilename(self._originalname)
if prs != self._originalname:
dfn = self.rotation_filename(self.baseFilename)
sfn = os.path.dirname(self.baseFilename) + "/" + self.parseFilename(self._originalname)
... do something useful here.. however, when using self.rotate the log entries get written into the original name, not the new one...
