             Summary: Customize log_filepath to allow files writen to NFS-shares
                 Key: AIRFLOW-1371
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1371
             Project: Apache Airflow
          Issue Type: Improvement
          Components: models
    Affects Versions: Airflow 1.8
            Reporter: Alexander Bij
            Priority: Minor


To be able to send logs to a NFS-mount the folder and files cannot contain [reserved characters](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx) like:
* < (less than)
* > (greater than)
* : (colon)
* " (double quote)
* / (forward slash)
* \ (backslash)
* | (vertical bar or pipe)
* ? (question mark)
* (asterisk)

Airflow writes the logs with an ISO-datetime format. This file contains one of these characters.
There are some solutions. What I would like is a configurable log_file_format to create log-files.

{code:python}
# Fetched by views.py and written by models.py currently like this:
    @property
    def log_filepath(self):
        iso = self.execution_date.isoformat()
        log = os.path.expanduser(configuration.get('core', 'BASE_LOG_FOLDER'))
        return (
            "{log}/{self.dag_id}/{self.task_id}/{iso}.log".format(**locals())){code}
