Checking site usage analysis

I have recently noticed that on one of our Sharepoint environments the usage analysis processing was not running on one virtual server.To solve this issue I found the following article on the Microsoft site: Usage Analysis Tools in SharePoint Products and Technologies

To check if the usage analysis processing is running for a specific virtual server use the following command:
stsadm -o getproperty -pn job-usage-analysis -url http://<virtual server URL>

To configure the usage analysis processing use:
stsadm -o setproperty -pn job-usage-analysis -pv “daily between hh:mm:ss and hh:mm:ss” -url http://<servername>

After setting this property, the usage analysis processing worked fine again.
