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.
与 nmon 类似,但输出为 JSON 格式,可以用于服务器性能统计。
