#### 1、介绍
本工具用与日志记录python程序内存信息，包括内存对象数量(memory type num)，内存对象增长(memory type num increment)，以及堆内存信息(memory heap info)。
#### 2、使用方式
示例：
```python
import time
import debug_util
class Int:
def __init__(self, value):
self.value = value
def new_int(i1, rs1):
a = Int(i1)
rs1.append(a)
if __name__ == '__main__':
ml = debug_util.memory_logger(log_file_name='test', duration=2)
ml.add_target(debug_util.handlers.MEMORY_TYPE_NUM)
ml.add_target(debug_util.handlers.MEMORY_TYPE_NUM_GROWTH)
ml.add_target(debug_util.handlers.MEMORY_STACK)
ml.start()
rs = []
i = 0
while True:
if i % 1000000 == 0:
time.sleep(2)
if i == 10000000:
break
new_int(i, rs)
i += 1
```
查看log/test.log文件
