Let me start by admitting there are likely a half dozen better ways to ingest the data but I don't have access to change that, thus I must learn how to manipulate what I have.
Goal: Take a dynamic set of ASCII numbers delimited by a "." and convert that to letters or punctuation and remove the delimiter.
Issue: I can isolate the sequence but have yet to find a method to convert the decimal number to ASCII character. My best lead thus far is find a way to convert the number to base16 and then use the SPLUNK function for URL decode.
If you are familiar with the MIB from JUNOS for jnxJSNatSrcNumSessions you are aware of the OID value is part standard and part dynamic based on the POOL NAME and IP structure. Structured as such "188.8.131.52.4.26184.108.40.206.220.127.116.11.1.6.<#i>.<#x>.<#y>.<#z>.0.192.168.0.0".
