Hi Brain,
This worked like a charm and saved couple of hundred lines of code as I
have 20 end points to monitor. One quick question, I have scraping metrics
for some of my spring boot applications and there are around 30
applications that I am scrapping metrics from. is there a way to use
file_sd to reduce the redundancy of the code just like the way it worked
for blackbox exporter.
Thanks
Eswar
