When creating a Graph Collection you will get an error like below:
Alert: ERROR: Sorry, but we can´t find any data using config file "ping.cfg", Read FAQ online
You need to rename the service to remove the colon ( : ) and the forward slash ( / ) characters. Note that renaming services will create a new graph and will disregard the old graph.
Will be fixed by MON-12438 that will disallow `:` and `/`object names by default upon creation.
