          "hostname" : "<hostname>",
          "cpuAddrSize" : <number>,
          "memSizeMB" : <number>,
          "memLimitMB" : <number>,
          "numCores" : <number>,
          "cpuArch" : "<identifier>",
          "numaEnabled" : <boolean>
   },
   "os" : {
          "type" : "<string>",
          "name" : "<string>",
          "version" : "<string>"
   },
   "extra" : {
          "versionString" : "<string>",
          "libcVersion" : "<string>",
          "kernelVersion" : "<string>",
          "cpuFrequencyMHz" : "<string>",
          "cpuFeatures" : "<string>",
          "pageSize" : <number>,
