在Python Linux环境下,可以使用psutil
库来监控磁盘IO性能
pip install psutil
接下来,可以使用以下代码示例来监控磁盘IO性能:
import time
import psutil
def monitor_disk_io():
while True:
disk_io_counters = psutil.disk_io_counters()
read_count = disk_io_counters.read_count
write_count = disk_io_counters.write_count
read_bytes = disk_io_counters.read_bytes
write_bytes = disk_io_counters.write_bytes
read_time = disk_io_counters.read_time
write_time = disk_io_counters.write_time
print(f"Read Count: {read_count}")
print(f"Write Count: {write_count}")
print(f"Read Bytes: {read_bytes}")
print(f"Write Bytes: {write_bytes}")
print(f"Read Time: {read_time} ms")
print(f"Write Time: {write_time} ms")
time.sleep(1) # 每隔1秒钟打印一次磁盘IO信息
if __name__ == "__main__":
monitor_disk_io()
这个代码示例会每隔1秒钟打印一次磁盘IO信息,包括读写次数、读写字节数和读写时间。你可以根据需要调整监控间隔或者添加其他功能。
