Yes. That 16 GB number is for the HICC server, not for the collection side. And even then, it's if you have a lot of data (a whole cluster's worth) living in a MySQL database with a web application serving the data.
The monitoring agent and the collector are both fairly small-footprint. --Ari On Sun, Dec 26, 2010 at 10:03 AM, Akshay Kumar <[email protected]> wrote: > Hi, > Thanks for the responses.
