njmon
njmon = nmon + JSON format + real-time push to a stats database + instant graphing of “all the stats you can eat” (AIX and Linux)
This njmon is a major overhaul of nmon for the next 10 years:
Load more stats
JSON format is self documenting, flexible and the performance stats format for many new tools
Direct real-time loading of the JSON into modern open source time aware databases
New age browser based graphing tools allow dynamic data choice and graph style per VM, per server or across the estateAll this will be covered and more including many demo’s.
And nmon similar, but the output is in JSON format, it can be used for server performance statistics.
