I have a script that queries servers in our environment to assist with  
patch-levels etc… I am having an issue and need to backtrace which  
class called my class.

What I currently have  
print “\nCollectData Failed 2: in needDate != yes & package == none  
#{hostName}\n”

What I would like to have  
print “\nCollectData Failed 2: in needDate != yes & package == none  
#{hostName}, called from #{callingClass}\n”

collectdata.rb:class CollectData  
collectdata.rb: print “\nCollectData  
Failed 1: in package != none and needDate == no #{hostName}\n”  
collectdata.rb: print “\nCollectData  
Failed 2: in needDate != yes & package == none #{hostName}\n”  
collectdata.rb: print “\nCollectData  
Failed 3: in needDate == yes #{hostName}\n”  
collectdata.rb: print “\nCollectData  
Failed: #{hostName}\n”  
rpmlist.rb: rpmInfo =  
CollectData.new(hostName)  
rpmmysql.rb: rpmInfo2 =  
CollectData.new(hostName,package.signature)

If I understand correctly what you want, try using the command +caller+  
to get what you want. It returns an array with current stack trace.
