Does nagios have any module for checking consistent global state in the distributed environment? If not, I would like to implement one possibly in java or c. I am more than sure you all know what global snapshot is but regardless I am attaching the link from wiki <a href="http://en.wikipedia.org/wiki/Snapshot_algorithm">http://en.wikipedia.org/wiki/Snapshot_algorithm</a>. Please give me some direction on this. Thanks -- Cordially, Shadhin Rahman
