The script compute the average time waiting time for block IO per device and prints list every 10 seconds. In some cases there can be too many oustanding block IO operations and the script may exceed the default number of MAXMAPENTRIES allowed. In this case the allowed number can be increased with "-DMAXMAPENTRIES=10000" option on the stap command line.</p></li> <li><a href="io/iostats.stp">io/iostats.stp</a> - List Executables Reading and Writing the Most Data<br> keywords: <a href="keyword-index.html#IO">IO</a> <a href="keyword-index.html#PROFILING">PROFILING</a> <br> <p> The iostat.stp script measures the amount of data successfully read and written by all the executables on the system.
