В случае, если кто-то еще пытается проанализировать / proc / diskstats с Python, как предложил Алекс:
def diskstats_parse(dev=None):
file_path = '/proc/diskstats'
result = {}
# ref: http://lxr.osuosl.org/source/Documentation/iostats.txt
columns_disk = ['m', 'mm', 'dev', 'reads', 'rd_mrg', 'rd_sectors',
'ms_reading', 'writes', 'wr_mrg', 'wr_sectors',
'ms_writing', 'cur_ios', 'ms_doing_io', 'ms_weighted']
columns_partition = ['m', 'mm', 'dev', 'reads', 'rd_sectors', 'writes', 'wr_sectors']
lines = open(file_path, 'r').readlines()
for line in lines:
if line == '': continue
split = line.split()
if len(split) == len(columns_disk):
columns = columns_disk
elif len(split) == len(columns_partition):
columns = columns_partition
else:
# No match
continue
data = dict(zip(columns, split))
if dev != None and dev != data['dev']:
continue
for key in data:
if key != 'dev':
data[key] = int(data[key])
result[data['dev']] = data
return result
