Hi everyone 

do you know  how can i monitor a external website with a additional path ?  

for example if a  try monitoring  " www.google.com " is working good with external node configuration  but in this case i need to monitoring this URL "">www.bkms-system.com/Tenaris"

if i put just "www.bkms-system.com" then  yes works 

any know how can fix this ? 

PD: I tried to config the aplication monitor " web link " and in the "URL" put the url what i want, but is doesn't work 

thanks!
