_load_criteria_map(self, setup_file=None)

source code

load the setup file and parse in the criteria. create a dictionary of criteria self.criteria_map

Example System Monitor setupfile:

   #gauge name, criterion
   gauge0,>50
   gauge1,>50
   gauge2,>50

the system monitor with trip when are gauge pressure exceeds (or the opposite of exceeds) the criterion.

Parameters:

setup_file (str) - absolute path of the setup file

Note: there is no established opposite of exceeds

_pressure_changed(self, object, name, old, new)

source code

Parameters:

object (BaseGauge) - a gauge object
name (str) - trait name
old (str) - the previous value
new (str) - the new value

record_error(self, msg)

source code

record an error

Parameters:

msg (str) - an error message
