Generating Performance Statistics by Using the rastat Utility

rastat.pl is a command line utility that runs tests against the Recovery Appliance to gather performance statistics which can help you identify system bottlenecks.

The tests can generate statistics on:

  • backup data sent to the Recovery Appliance over the network

  • restore data received from the Recovery Appliance over the network

  • Recovery Appliance ASM disk group read or write I/O

  • Recovery Appliance container file read or write I/O

  • Recovery Appliance container file allocation rate

The utility is a Perl script that can be run from any Linux or Unix-based client machine that is either a protected database or an upstream Recovery Appliance. The I/O tests however, can also be run directly from the Recovery Appliance server.

You can run multiple tests in parallel on one or more protected databases to simulate a real environment. Each test result represents the performance of an individual client. Note that ongoing activities between other protected databases and the Recovery Appliance being tested, such as backup and restore or other testing, can impact the resulting statistics.
