Dustin,
thanks for the great advice, I have just installed the elasticsearch-hq plugin. This provides immensely useful information and gives a way better overview on the cluster status. (way better than parsing through the curl output).
I’ve read in the elasticsearch documentation that it is recommended to disable swapping on the ES server. https://www.elastic.co/guide/en/elasticsearch/guide/current/heap-sizing.html#_swapping_is_the_death_of_performance
Because also the elasticsearch-hq plugin indicated that the elasticsearch server is swapping.
In the plugin I also see that the refresh rate of the Index activity is 13.98ms
I assume this value is not ideal and probably has to do with the documents being stored on NAS storage rather than local disks. Does the refresh rate correspond directly with search performance (or displaying dashboards) ?
Have a great day!!
