很久以前写的代码，在windows下获得CPU和内存使用情况：
1 import win32pdh
2
3 # Counter paths
4 PROCESSOR_PERCENT = r'\Processor(_Total)\% Processor Time'
5 MEMORY_PERCENT = r'\Memory\% Committed Bytes In Use'
6 MEMORY_COMMITTED = r'\Memory\Committed Bytes'
7 PROCESS_BYTES = lambda x: r'\Process(%s)\Private Bytes' % x
8
9 class Query:
10 def __init__(self):
11 self.counters = {}
12 self.query = None
13 self.query = win32pdh.OpenQuery(None, 0)
14
15 def add_counter(self, path):
16 if win32pdh.ValidatePath(path) != 0:
17 raise Exception('Invalid path: %s' % path)
18 counter = win32pdh.AddCounter(self.query, path, 0)
19 self.counters[path] = counter
20
21 def remove_counter(self, path):
22 win32pdh.RemoveCounter(self.counters[path])
23 del self.counters[path]
24
25 def get_values(self):
26 values = {}
27 win32pdh.CollectQueryData(self.query)
28 for path in self.counters:
29 status, value = win32pdh.GetFormattedCounterValue(
30 self.counters[path], win32pdh.PDH_FMT_LONG)
31 values[path] = value
32 return values
33
34 sysinfo_query = Query()
35 sysinfo_query.add_counter(PROCESSOR_PERCENT)
36 sysinfo_query.add_counter(MEMORY_PERCENT)
37 sysinfo_query.get_values()
38
39 def get_sysinfo():
40 """Return a tuple (mem_usage, cpu_usage)."""
41 info = sysinfo_query.get_values()
42 return info[MEMORY_PERCENT], info[PROCESSOR_PERCENT]
*nix系统下，用管道分析 uptime 和 free 命令的输出就可以了。
