I have no knowledge of JSON format so this may not be possible. Please let me know if it is/isn't possible.
My issue is that I have a field called logMessage. A sample of what is stored in there looks like this:
Starting process 'the_process' with parameters 'some parameters'
What I want to do for my pie chart visualization is split on the logMessage field and pull out the part that is in the first single quotes (the_process) and display those fields on the pie chart with the count.
