Please > > clarify what you would like changed. Thank you. Hi, from the naming of the item I was expecting it to be total hugepages on the host, not just the free ones. What I would really like for it to say something like: "Huge Pages (size: total amount / free): 1048576: 2 / 2" or something like that. Greetings Klaas (In reply to Steven Rosenberg from comment #1) > Created attachment 1696874 [details] > Huge Pages Displayed in the Host > > We currently display the size and amount as per the screen shot. Please > clarify what you would like changed. Thank you. As mentioned in comment #0, it is not clear if those numbers are free, used or totals. And I think it should be also improved, displaying total and free, or total and used.

The 2048 is the amount of free huge pages of the given size. So the label does show that for a given page the format is the "size: amount". What format would you like specifically that would be clearer to you? There are two values per page, size and amount. [1] https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/restapi/jaxrs/src/main/java/org/ovirt/engine/api/restapi/resource/HostStatisticalQuery.java#L72-L73 I think we can avoid the confusion about what is currently presented by simply replacing "Huge Pages" with "Free Huge Pages". As for adding the total huge pages, this should probably be a separate RFE. (In reply to Arik from comment #6) > As for adding the total huge pages, this should probably be a separate RFE. Filed bz 1848579 for that @Michal Skrivanek - I am guessing you mean fixed in rhv-4.4.1-11 ?
