Kibana Elasticsearch Shards and replication


(Tony Chong) #1

Hi everyone,

Sorry if this has been covered but a few pages of searching through the
group hasn't sprung an answer for this.

If I decided to have 3 elasticsearch nodes, with 3 shards, and 0 replicas,
would kibana be able to retrieve all the data in my ES cluster or just the
data from the elasticsearch listed in its configuration, considering not
all the shards would live on that node?

Thanks,

Tony

Once you have a cluster, all data on any node is accessible.
It does this by passing the query to the master node which then collects
the data as required from the other nodes.
