Subject how is failure detection achieved in cloudstack?
Date Tue, 09 Apr 2013 11:45:24 GMT
I would like to know how the process of failure detection is achieved in
cloudStack (if any). I would like to know about the implementation details,
i.e. if its done at physical, virtual machine or at application level. Does
cloudStack use any known failure detection mechanisms? e.g. [1][2][3][4] or
any other. Where can I find this information?

Thank you in advance.
