还有一个问题， ./sonic-ios-bridge perfmon --sys-cpu --sys-mem --sys-disk --sys-network --fps --gpu -r 2000
-r 参数我写的是刷新数据的时间，可是设置5000毫秒后，sys的指标不会显示出来， gpu和fps 倒是实时显示出啦，
所以这个 -r 参数目前是有问题的。不会按设置的时间显示出来，会一直打印 gpu 和 fps的数据：
{"type":"fps","timestamp":1677840711,"fps":9}
{"type":"gpu","timestamp":1677840712,"tiler_utilization":6,"device_utilization":6,"renderer_utilization":5}
{"type":"fps","timestamp":1677840712,"fps":9}
{"type":"gpu","timestamp":1677840713,"tiler_utilization":10,"device_utilization":11,"renderer_utilization":9}
