Both. Fault Tolerant and orders of magnitude faster. >> If so, which distributed file system did you use? >> HDFS (hadoop?) >> lustre ?

Yep, that is what I thought; nothing preventing jffnms from running on a linux cluster. There are many such clusters, hadoop is probably the most common and overly complex linux clustering technology. Openstack, mesos and beowolf are also well known. The really cool thing about 'apache-spark' is it is an 'in-memory' technology. So when it is applied to streaming data, it renders results in 'real-time'. Figuring out how to support that real-time display along with concurrent data writes every period (say 3 minutes) is going to be the trick, imho. Many distros provide binaries for mesos+spark, so setting up a cluster is pretty straightforward (debian, centos, ubuntu, etc). I use gentoo, so it's been another adventure preparing everything from source codes. If anyone is interested, I'll gather up some links to show what is needed to run a simple linux cluster, upon which jffnms could be tested. Mesos is the one that is currently the hot cluster-technology. Maybe the next release of jffnms is branded, mesos-ready? (That would attract many new folks to jffnms). hth, James ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
