Hello. May be this question already answered, but i can't see it in list archive.
I'm running about 60 Xen nodes with about 7-20 virtual machines under it. I want to gather disk,cpu,memory,network utilisation from virtual machines and get it into database for later processing. As i see, my architecture like this - One or two master servers with mpi process with rank 0, that can insert data into database. This master servers spawns on each Xen node mpi process, that gather statistics from virtual machines on that node and send it to masters (may be with multicast request). On each virtual machine i have process (mpi) that can get and send data to mpi process on each Xen node. Virtual machine have ability to migrate on other Xen node.... Please, Can You help me with architecture of this system (is my thoughts right) ? And one more qeustion - that is the best way, to attach mpi process to already running group? (for example, virtual machine is rebooted, or may be Xen node rebooted).... Than You for any answers... -- Vasiliy G Tolstov <v.tols...@selfip.ru> Selfip.Ru
