# ioping > Monitor I/O latency in real time. > More information: . - 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|-count]}} 10 {{[-s|-size]}} 1M /tmp` - Measure disk seek rate on `/dev/sdX`: `ioping {{[-R|-rapid]}} {{/dev/sdX}}` - Measure disk sequential speed on `/dev/sdX`: `ioping {{[-RL|-rapid -linear]}} {{/dev/sdX}}`
