hello archers, thought i ask here first, before i try some kernel mailing list. i'm writing (for fun) a tiny daemon that sends linux usage (cpu, mem, net, etc.) statistics as efficiently as possible to another machine, repeatedly, to get "live" data. at the moment i'm simply sending /proc files, but they sometimes have too much data. so was wondering if there is a more efficient way to get (only parts of) the data thats available in /proc? for example, /proc/meminfo has all this info: MemTotal: 8051660 kB MemFree: 6046020 kB MemAvailable: 6843080 kB Buffers: 109116 kB Cached: 708336 kB SwapCached: 0 kB Active: 1332416 kB Inactive: 455428 kB Active(anon): 971040 kB Inactive(anon): 22340 kB Active(file): 361376 kB Inactive(file): 433088 kB Unevictable: 16 kB Mlocked: 16 kB SwapTotal: 1048572 kB SwapFree: 1048572 kB Dirty: 16 kB Writeback: 0 kB AnonPages: 970412 kB Mapped: 323384 kB Shmem: 23008 kB Slab: 71760 kB SReclaimable: 44860 kB SUnreclaim: 26900 kB KernelStack: 6544 kB PageTables: 22924 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 5074400 kB Committed_AS: 3487604 kB VmallocTotal: 34359738367 kB VmallocUsed: 0 kB VmallocChunk: 0 kB HardwareCorrupted: 0 kB AnonHugePages: 413696 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 168600 kB DirectMap2M: 8091648 kB but i only need: MemTotal: 8051660 kB MemAvailable: 6843080 kB Cached: 708336 kB event better would be if kernel would only tell me: 8051660 6843080 708336 if /proc is the only way to get this info, i wonder if creating a kernel module for this would be more efficient, or even possible?
