Provides performance reports with suggestions for making configurational changes to the environment, and helps to identify areas for further investigation. The reports are based on the key performance metrics of various partition resources that are collected from the Virtual I/O Server (VIOS) environment.
You can use the part command to start the VIOS Performance Advisor tool.
By using the VIOS command-line interface, run the part command to start the VIOS Performance Advisor tool.
When you start the VIOS Performance Advisor tool in the on-demand monitoring mode, provide the duration for which the tool must monitor the system in minutes. The duration that you provide must be 10 - 60 minutes at the end of which the tool generates the reports.
When you start the VIOS Performance Advisor tool in the postprocessing mode, provide the command with an .nmon file as input (-f FILENAME). If the recordings do not have all the required data for the advisory tool to produce the reports, it adds Insufficient Data messages to the relevant fields.
The vios_advisor.xml file structure is based on an XML schema definition (XSD) located in the /usr/perf/analysis/vios_advisor.xsd file.
