Virtual I/O Server Advisor

Virtual I/O Server Advisor


Overview


The VIOS advisor is an application that runs within the customer's VIOS for a user specified amount of time (hours), which polls and collects key performance metrics before analyzing results and providing a health check report and proposes changes to the environment or areas to investigate further.
The goal of the VIOS advisor is not to provide another monitoring tool, but instead have an expert system view performance metrics already available to the customer and make assessments and recommendations based on the expertise and experience available within the IBM systems performance group.

Setup

  • Download vios_advisor.zip from the link provided in download section
  • Unzip vios_advisor.zip on a workstation that has a web browser.
  • ftp vios_advisor onto the VIOS you wish to monitor. (place in any directory)
  • chmod +x vios_advisor to give the application execution priviliges.

Steps to run VIOS Advisor

The application "vios_advisor" takes only one paramter, which is the duration of the the monitoring period, in minutes.
For example,to monitor the VIOS for 30 minutes run:
vios_advisor 30
Usage Statement:
Usage: vios_advisor
duration_in_minutes:
Recommended monitoring time = >= 30 min
Minimum monitoring time = 5 min (only recommended for settings verification)
Maximum monitoring time = 1440 min (24 hours)
-v : Version

Results

The vios_advisor application is silent (does not produce any output to screen) and upon termination, will generate an xml file in the current running directory labeled:
vios_advisor.xml
Copy over the vios_advisor.xml file to the workstation where the zip file: vios_advisor.zip was extracted, and place the file in the vios_advisor folder.
Open the vios_advisor.xml file with the web-browser of your choice to see the report.
