MANAGEABLE

Dictionary defintion

Lower TCO

Increase availability and uptime

Management can be a Key Differentiator

Monitoring System State using WMI IndicationsDemo

Don’t invent your own mechanism, use standards.

Writing WMI providers is

easy.Support for standards ensures “Write once – manage from anywhere”.•Local or Remote•Windows or non-Windows client

WMI is well integrated with PowerShell to

provide rich experience to IT pros.

You don’t have to use printf()

We are making event logs easy to analyze
