Comparing methods for recording I/O - V$SYSSTAT vs HP Measureware

Read Original

This technical article compares two methods for recording system I/O data: using Oracle's V$SYSSTAT view via a PL/SQL script and using HP's MeasureWare tool at the OS level. The author graphs the results using rrdtool and demonstrates that the data from both sources aligns almost perfectly, providing explicit validation of the measurement accuracy.
