Re: [zones-discuss] Per-zone CPU Usage Reporting?
Hello, Jeff! Have you tried prstat -Z? Is this not what you are looking for?

If you don't have many short running processes, this is not a big deal. However, if you have a print server, software builds, and sometimes misbehaving applications, such approaches miss the bulk of the workload. I've solved this, but in code I sadly can't share.

Re: [zones-discuss] Per-zone CPU Usage Reporting?
Hernan, In addition to Mike's point about short-lived processes, prstat doesn't tell me how much CPU time a process used during its life. Solaris Accounting will generate a record for each process, showing how much CPU time it used, and which zone it was in. If you collect all of the records, you can sum CPU time for each zone. They need a tool which uses those records for input and generates a report for chargeback. --JeffV On Fri, Sep 18, 2009 at 9:31 AM, Hernan Saltiel hsalt...@gmail.com wrote: Hello, Jeff!

Re: [zones-discuss] Per-zone CPU Usage Reporting?
That's right, there is a key term here, and is reporting, which involves accounting. Thanks, Jeff! Best regards, HeCSa.
