Hi,
In our apache logs we also log response time with the %D parameter. We would also like to add this field to the filebeat logs so we can analyse it in Kibana.
I can manage to add an updated grok pattern to the filebeat pipeline, however everytime we update our Elastic Cloud version, this seems to be overwritten. I guess because the field is not defined in ECS?
Is there anyway to keep the changes I apply to the pipeline patterns persisted when we upgrade to new versions?
