Check when iMac was woken from Sleep?

[seble]

Hi all.
I'm a student, and on a limited broadband plan here in the UK. I thought it was going to be the start of a beautiful month now that my broadband had been reset back to 0gb in the past couple of days, but since the Mac update 10.8.4 my iMac data usage has sky rocketed!!

I updated OSX last night (off peak allowance) and yesterday my computer downloaded 20Gb in the day! I checked my history a couple of youtube videos, but nothing that would make it climb so high!

I emailed them and they showed me when the most was being downloaded. Is there a way to check to see what times the iMac was woken from sleep as you can do with startup? this would be useful in seeing if the times correlate.

tldr: can I check to see what times the Mac was woken from sleep? Is there anyway to check what data my mac was downloading? Thanks

Check the Console for hints.

Thanks, not sure what to be looking out for exactly. It appears to be mostly outdated anti-malware software 'talking' in there.

That's all I can really see in here. Anything else I can do that might help?

Using the Console utility, look at the kernel log. Mine has the following lines from when I woke the system up from sleep this morning:

Jun  7 07:45:15 cider kernel[0]: Wake reason: EHC2
Jun  7 07:45:15 cider kernel[0]: Previous Sleep Cause: 5
Jun  7 07:45:15 cider kernel[0]: The USB device HubDevice (Port 1 of Hub at 0xfa000000) may have caused a wake by issuing a remote wakeup (2)
Jun  7 07:45:15 cider kernel[0]: The USB device Keyboard Hub (Port 4 of Hub at 0xfa100000) may have caused a wake by issuing a remote wakeup (3)
Jun  7 07:45:15 cider kernel[0]: The USB device Apple Keyboard (Port 2 of Hub at 0xfa140000) may have caused a wake by issuing a remote wakeup (3)

Note that you could get some other messages in between the various wakeup messages.

Thanks all, that was much help, especially telling me which log to look in! The data mystery continues
