The filter option available in Kibana applies to all the metrics.
How can I set separate filter for each individual metric in a single Kibana visualization?
Can someone suggest anything on this?
I don't think it's possible to apply a filter to one metric but not others. Filters in Kibana are pretty tightly coupled to the aggregation query it generates. You can add multiple metrics and aggregations in a single request, and thus a single visualization, but any filters will apply to the entire request.
