# ioping > monitor I/O latency in real time - Show disk I/O latency using the default values and the current directory `ioping .` - Measure latency on /tmp using 10 requests of 1 megabyte each. `ioping -c 10 -s 1M /tmp` - Measure disk seek rate on /dev/sda. `ioping -R /dev/sda` - Measure disk sequential speed on /dev/sda. `ioping -RL /dev/sda`
