Hello All.
I am trying to use values, retrieved from a config file, as kwargs and not
having any luck. Well at least I think that's what I'm trying to do ;)
Any suggestions would be most appreciated.
Here's the exception:
Traceback (most recent call last):
File "c:\dev\LogServerMonitor\LogServerMonitor.py", line 246, in <module>
sched.add_cron_job(check_logging_db, minute = '*/run_interval_quantity')
File "c:\Python26\lib\site-packages\apscheduler\scheduler.py", line 249,
in add_cron_job
second)
File "c:\Python26\lib\site-packages\apscheduler\triggers.py", line 22, in
__init__
self._compile_expressions(minutes, 'minute')
File "c:\Python26\lib\site-packages\apscheduler\triggers.py", line 43, in
_compile_expressions
compiled_expr_list = [compile_single(expr) for expr in expr_list]
File "c:\Python26\lib\site-packages\apscheduler\triggers.py", line 36, in
compile_single
(expr, fieldname))
ValueError: Unrecognized expression "*/run_interval_quantity" for field
"minute"
An example of what I am doing is:
######################################################################################
Config File Contents:
[RunInterval]
#How often the application queries the DB to look for the date of
#the last entry (Default every 1 Minute).
#Valid RunInterval Quantities are integers > 0
RunIntervalQuantity: 1
#Valid RunInterval Types are S=Seconds, M=Minutes, H=Hours, D=Days
RunIntervalType: M
