How can I access associated data from my alarm tag ‘Alarm Active’ event script?
Currently I have this, but it’s not working:
Associated Data defined
Script in ‘Alarm Active’ event
and the error
It seems that alarmEvent.get(“associated data name”) is not working in alarm event…?
Hi zxcslo, there appears to be a bug with the alarmEvent.get() function in the context of Tag Event scripts. However there is a workaround. Please copy the unicodeDataToDict() and getActiveData() function into your script and call getActiveData() with alarmEvent as the function parameter. This will return a dictionary object in which you can access your associated data with the [] operator. See below for an example.
# Converts the unicode string returned by activeData.toString() into a python dictionary
def unicodeDataToDict(unicode):
import ast
# Makes sure the unicode conforms to dictonary format by doing various string replacements
unicode = unicode.replace("{", "{'")
unicode = unicode.replace("}", "'}")
unicode = unicode.replace('=', "':'")
unicode = unicode.replace("," , "','")
unicode = unicode.replace("' " , "'")
# Converts the unicode string to a dictionary object
return ast.literal_eval(unicode)
# Returns various alarm properties including associated data as a python dictionary
def getActiveData(alarmEvent):
activeData = alarmEvent.getActiveData()
# We can't explicilty access the data inside activeData so perform a workaround here.
# Calling the print() function on an activeData object will return a unicode string containing
# various alarm property names mapped to its corresponding values.
# E.g. {name=myAlarm}
# We will then format this unicode string so that it conforms with the syntax of a python dictionary
# and then convert into a dictionary object
activeDataDict = unicodeDataToDict(activeData.toString())
return activeDataDict
activeDataDict = getActiveData(alarmEvent)
# You can access alarm properties by doing: activeDataDict['NAME_OF_ASSOCIATED_DATA']
# Note that all values in the dictionary are in string format so it may be necessary
# to do some casting.
deviceName = activeDataDict['deviceName']
hostname = activeDataDict['hostname']
Cool… It’s working. Thank you. 
Can we expect this bug to be resolved soon?
I have submitted a ticket for this bug, but unfortunately there is currently no estimate for when it will be resolved. I will update this thread when it has been fixed.
