Hi Is there any way using SCCM that I can work out automatically which machines are switched on at night? Regards D

Hi, There is no default feature (yet) that will tell you if a computer is running right now or not. With R3 (currently in public Beta), you will be able to configure collection based power rules. With those rules you can power down computers etc. Furthermore each client will report how much power they using daily, weekly etc. For now you can create a custom solution eg. where you ping the computers at night and pick up the responses.Kent Agerlund | http://scug.dk/members/Agerlund/default.aspx | The Danish community for System Center products

If you just want to know when they last booted then you can look at the last boot time in inventory or I am sure you can get creative with DCM. But otherwise I think you will need to wait for R3 to give you more information. What are you trying to accomplish or look at? http://www.sccm-tools.com http://sms-hints-tricks.blogspot.com

If you wanted to see which computers are on at night, you could do so with a hardware inventory timestamp query. For example, the following query would tell you if a computer ran a hardware inventory between 10pm and 3am: select SMS_R_System.ResourceId, SMS_R_System.ResourceType, SMS_R_System.Name, SMS_R_System.SMSUniqueIdentifier, SMS_R_System.ResourceDomainORWorkgroup, SMS_R_System.Client from SMS_R_System inner join SMS_G_System_WORKSTATION_STATUS on SMS_G_System_WORKSTATION_STATUS.ResourceID = SMS_R_System.ResourceId where DATEPART(HH, SMS_G_System_WORKSTATION_STATUS.TimeStamp) > 22 or DATEPART(HH, SMS_G_System_WORKSTATION_STATUS.TimeStamp) < 3 You would have to schedule inventory to be at night or push out a script. Of course, if they run inventory later they would fall out of the script, so you would need your collection refresh to happen at about 3:00am in the example above. You could use anything that has a timestamp field, such as Advertisement Status, Patch Scanning, Software Inventory or Heartbeat Discovery.
