Extract value from string in kibana

Question

My logs are added in kibana, the logs are in string format. Consider a log line is like 'Total Execution time 1s' I need to extract 1 from this line and put this in some graph or sum it.

Can someone please guide how to do that.

Answer 1

Manipulation of String can be done b Logstash using GROK input filter. Or at Elasticsearch Ingest node using similar filter.

Once the String is parse and stored in an appropriate field, you can visualize it on Kibana. Kibana itself cannot parse a field.
