Hi, Thanks for the responses. A bit late to check this one. I have one more query - In the Chukwa administration guide: http://people.apache.org/~eyang/docs/r0.1.2/admin.html It says *Chukwa* can also be installed on a single node, in which case the machine must have at least *16 GB of memory. *
Q) For my usecase ( for monitoring system metrics) - is it safe to assume it is not going to be that big a requirement for memory?
