X can be mem_total, mem_free, or any other parameter. For computing an average across multiple hosts: 1. Get value of X from every host, 2. Sum X's received, 3. Do percentage computation. If there is only one HAWQ Segment it would have been correct - it would be the Percentage memory utilized for that host: ((mem_total - mem_free - mem_cached)/mem_total) * 100 If there are multiple hosts, to get the aggregate percentage across all hosts this is the required formula: ((mem_total._sum - mem_free._sum - mem_cached._sum)/mem_total._sum) * 100 - Matt ----------------------------------------------------------- This is an automatically generated e-mail.
