I have deployed ELK system to monitor kubernetes clusters logs from different data-centers and environments. I would like to be able to filter logs based on cluster's name. Is it possible to add my own customize tag (variable) to elastic search or Kibana tags so it will filter logs base on that.
For example I want to add kubernetes.cluster_name tag to fields in Logstash* so I can create a dashboards based on that tag.
Any assistance would be greatly appreciated.
