I have a workbench which has a complex custom transformer added in which a python caller is present. I wanted to check what is happening in that python caller so I used some print statements. But I cannot find those print statements in logs that is being generated. How to get the log of a custom transformer in FME Desktop 2019.

Print statements will appear in the on-screen log window, but will not necessarily be logged in the exact same order as the transformer messages, and may only appear on-screen and not in the log file.
The best way to log messages is to use the FMELogFile object in the fmeobjects API. Example:
import fmeobjects
def my_function(feature):
# Do something ...
# Sends a message to the FME log file and console window.
# Severity must be one of FME_INFORM, FME_WARN, FME_ERROR,
# FME_FATAL, FME_STATISTIC, or FME_STATUSREPORT.
message = 'This message will appear both on screen and in the log file'
severity = fmeobjects.FME_INFORM
fmeobjects.FMELogFile().logMessageString(message, severity)
# Do something else here...

Got it.. Thanks
