会在POD日志中得到：(所有数据都有[FILE]作标识)

• 每秒钟的读写文件速率

2023-11-09 01:32:26.793 [FILE] read 185 Kbytes/sec write 0 Kbytes/sec

• 读写文件信息

[FILE] func fetch_container_id path /proc/10472/cgroup
[FILE] func get_process_starttime_and_comm pid 10472 name du
2023-11-09 01:32:11.711 [FILE]  PID 32723 TID 3685 comm cp_reader read 391 bytes latency 26408ns filename cgroup

• 如果读写超过了4Kbytes大小，会在PID前面加一个A, 便于检索

2023-11-09 01:31:24.658 [FILE] A PID 32723 TID 3685 comm cp_reader write 8192 bytes latency 30208ns filename bcc_32723_vdso_image_tqKFJR
