I have these splunk output event in splunk logs. 1 event is for one specific server only. Under one server we have 5 services running and associated memory information. These output is in table format. I like to create regular expression so that I can create table format output as below:



Servername          Servicename               Memory(in MB) (since above memory in bytes)

Why use a regular expression when Splunk has a command specifically for this data format?  Check out the multikv command at https://docs.splunk.com/Documentation/Splunk/8.2.4/SearchReference/Multikv
