Discover: Gateway timeout error

I am getting gateway timeout error while discovering the index in kibana, but for the same index, I am able to see dashboard and visualization.


Thanks in advance.

Hey @Ranjith_B_K,

Maybe Kibana has a very slow connection to Elasticsearch and can't retrieve all the records Discover wants to return (500 by default). Have you tried reducing the value of discover:sampleSize in Kibana Advanced Settings?


Thanks @azasypkin, reducing the sampleSize value made it work.
