I have a discovery rule using "vfs.fs.discovery" for the key. I need to be able to strip the trailing \ on the returned value, as I'm trying to create items such as perf_counter["\logicaldisk(C
\% Disk Write Time"] and the vfs.fs.discovery returns C:\, which obviously won't work as the perfcounter doesn't exist.
Is there a way to strip out the last character, or to use a regex to extract the first few chars (for example \w: )?
