Detailed Explanation
“IOPS” stands for “Input/Output Operations Per Second.” IOPS is an important performance metric for storage devices that shows number of read/write operations that a storage device can perform per second. A high IOPS number means that a storage device is capable of performing a large number of read and write operations in a very short amount of time. This can be beneficial for applications and systems that require fast and efficient access to storage resources. If there is a sudden drop in IOPS, it could indicate a problem with the storage system or with one of the applications running on the system.
Iotop is an interactive real-time I/O usage monitoring tool to check disk read and write bandwidth usage for each running process on Linux.
#install iotop on Ubuntu
$ sudo apt update
$ sudo apt install iotop
#Check Total IO Usage Per Process
$ sudo iotop -ao
#Check Process ID instead of TID in iotop
$ sudo iotop -P
#Filter by Process id or username
$ sudo iotop -P -p <PID> -p <PID>
$ sudo iotop -P -u <USERNAME1> -u <USERNAME2>
IOPS via network is largely a function of block size divided into bandwidth. 1gbit is about 125MB/sec, divide that by 4KB(block size, for example) or whatever your block size is and you get about 32,768. the max number of IOPS over 1gbit network.
Best Practices
- 최신 버전 사용 권장
- 공식 문서 참고
- 테스트 환경에서 먼저 검증
