Thanks. Ho
As VW mentioned, we're running our ELK clusters on a nova undercloud.
My elasticsearch cluster looks like this:
* 3 master nodes
* 6 client nodes (these nodes are running elasticsearch as clients only -
no data storage. they handle all api requests. they're also running kibana)
* 40-ish data node

Nathan: The page at

gives you good advice on a maximum size for the elasticsearch VM's memory.
Nathan: suggest you pick a flavor with 64GB RAM or less, then base other sizing

cache so that Lucene can make best use of it.

Hi,
I had some “interesting” issues in the past with sparse files on xfs with
elasticsearch:

If you pre-allocate your files you should be good.

We are running entire ELK clusters on our undercloud. Let me see if I can
point our resident metrics expert at this as well.
