Hi, I am very new to elasticsearch, at my company we are testing the data base and we are trying to create a cluster with 2 nodes, one master node and one only search node.
We already had the two nodes up and running, at the search node config we spcified the values:
And the cluster shows the two nodes already, but, when we check the node diagnostics using HQ we see that the search node has no activity, is something missing on the configuration file?
Thanks in advance.
PD: We do not need a replica node, the data we are storing is volatile so it is not importan to us to have a replication schema, we just one to set up one master and data node, and one search only node.
This is our cluster diagnostics:

How this Field is Calculated
High values indicate slow I/O.
Keys: stats.indices.flush.total_time_in_millis / stats.indices.flush.total
Value: 54094103 / 44993 = 1202.2781988309293
1202.2781988309293 <= 750 = Pass!
1202.2781988309293 <= 1500 = Warning!
