I would like to be able to find out how many times a character appears in a field. Is this possible with grok or some other filter?
To explain, we are getting beats from multiple sources, and multiple departments in my company. There is a standardized field, that has a delimiter character, which I use dissect its data. However, we have a new division that needs more information and wants to increase the amount of delimited data in this field. The issue I have is that the added information is an inside delimited value. The below is a quick example, where there is an extra value ( -loc- ) inside. And, of course there are very different rules for processing these.
My thought is to count how many dashes there are to know how to process. Is this doable in a Logstash filter (grok?), or is there another approach that I should consider?
