Extract values from log message

Hi
I am using Grafana 7.0.3 with ElasticSearch 7.4
I have logs in my system with various values. I want to be able to extract those values from the log field, and use them to create the graph (specifically i have an organization (enum) value, and time value in ms - both part of the log message)
I cant find how to get these values from the log string using Lucene Queries.

Is this even possible ? and If so were can I find the syntax.

Thanks.

Very possible, use logstash…
The script depends on the log format that you want to parse.

For the specific log format, you need to build the specific grok syntax.
