文件
基本用法:
>>> from hazelnut import MemInfo >>> mem = MemInfo() >>> mem MemTotal: 8092252 kB MemFree: 5444872 kB MemAvailable: 7138880 kB Buffers: 484724 kB Cached: 1299716 kB SwapCached: 0 kB Active: 1732744 kB Inactive: 671312 kB Active(anon): 509420 kB Inactive(anon): 111312 kB Active(file): 1223324 kB Inactive(file): 560000 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 16776188 kB SwapFree: 16776188 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 619632 kB Mapped: 96216 kB Shmem: 1120 kB Slab: 184200 kB SReclaimable: 159252 kB SUnreclaim: 24948 kB KernelStack: 3856 kB PageTables: 5664 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 20822312 kB Committed_AS: 1755880 kB VmallocTotal: 34359738367 kB VmallocUsed: 362896 kB VmallocChunk: 34359343324 kB HardwareCorrupted: 0 kB AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 97980 kB DirectMap2M: 8187904 kB
返回输出为dict类型:

搜索 (不区分大小写):
>>> mem.search('Swap')
['SwapCached: 0 kB\n', 'SwapTotal: 16776188 kB\n', 'SwapFree: 16776188 kB\n']
获取内存使用为int类型 (不区分大小写):
>>> mem.get('Inactive(anon)')
