Hi there, am trying to create a "metric visualization" to show the count of the "number of instances matching a text pattern", but do not see that field within the list of eligible fields when trying to use.
From the mapping, I do see it's a "text" field. Can we use grok filters on a field (say, log message) within a Kibana visualization? Or can they be used only within logstash to ingest data into elastic?
Here's what I mean:
Each document ingested into Elastic contains a text field called "log" with "SQLException" (somewhere within certain documents).
I am looking for a way to dashboard the total number of occurrences of "SQLException" in the text field called "log".
Thanks!
