When writing Java Script Impact Policies I noticed the following:
In the below code example Log(error.stack) seems to only output a truncated stack
trace, which isn't really much use in debugging. I see that I can use error.message,
but that does not give me the same output as if I hadn't bothered with try/catch at
all. It would be nice if error.stack offered full output (see below for
details)?
try {
//some code
}
catch(error) {
Log("An error occured during policy Execution...see stack trace below.");
Log(error.stack);
Log(error.message);
}
finally {
//some code
}
When ran against an example I got the following output:
20 Nov 2020
12:08:41,467: [TEST_TT_MonitorAutoticketJS][pool-2-thread-102283]Parser
log: An error occured during policy Execution...see stack trace below.
Log(error.stack) output: 20 Nov 2020
12:08:41,468: [TEST_TT_MonitorAutoticketJS][pool-2-thread-102283]Parser
log: at pool-2-thread-102283:733 (main)

Log(error.message) output: 20 Nov 2020

log: com.micromuse.common.util.NetcoolException: Die Datenquelle
NCOMS_SPUx ist nicht vorhanden.
For error.stack I would have expected something like:
20 Nov 2020
