Examples of rwtime-nd.stp, the Linux SystemTap version. rwtime-nd.stp measures syscall read() and write() times, summarizing them as histograms. A process name can be specified. For example, to measure read() and write() latency from processes named "node": # ./rwtime-nd.stp node Tracing read/write syscalls for processes named "node"... Hit Ctrl-C to end. ^C syscall read latency (ns): value |-------------------------------------------------- count 512 | 0 1024 | 0 2048 | 2 4096 |@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 278 8192 | 1 16384 | 5 32768 | 0 65536 | 0 syscall write latency (ns): value |-------------------------------------------------- count 4096 | 0 8192 | 0 16384 |@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 135 32768 |@@ 8 65536 | 0 131072 | 0 Those reads and writes were very fast, between 4 and 32 microseconds. Here's an example with much higher latencies: processes named "bash": # ./rwtime-nd.stp bash Tracing read/write syscalls for processes named "bash"...
