    My computer sent/received exactly 2GB data yesterday evening but I don't know what was it. I found it out because my internet connection has 10GB months limit (wireless) so when I connected at 8pm I had 4.5GB left but at 11pm I had just 2.5GB left. I didn't watch any videos or HD pictures just read articles. Also, I had photo stream disable and denied automatically download all attachments in my email client. I'm not aware that system downloaded any updates.
    Is any possibility to find out in system what was uploaded/downloaded backward in time?
    I haven't used any third party apps for data monitoring.
    My OS X version is 10.9.2

    Thanks for answer

    You can see if updates downloaded by opening the App Store and it will show the updates downloaded in the last 30 days. I recommend downloading the free application Bandwidth+ from the App Store.

    Also, if possible, you should look at finding a new ISP if you can afford it. In this day and age 10 GB a month is being surpassed by some people on just cell phones, let alone full computers.

    Thanks I'll try this app. Anyway, does exist any command in the terminal which can show the network data in/out history? I'm sure that system keeps a log process. Although I've tried to google it I've found nothing. That's why I'm writing here...
    Yep I know that this kind of connection nowadays is a little bit weird but I can explain it easily. I'm at the hotel so I don't have too many choices. Also, I'm using the unique voucher number which is just for one computer (hotel internet provider).
    And the main argument is, I'm in Australia and connection here is like in the third world :)

    I don't know of any terminal command that shows network bandwidth used at a particular time. "ifconfig -a" will show total network bandwidth used since the last reboot, but that doesn't tell you what was using the connection at some point in the past.

    If you catch it while the network traffic is being used, you can look at Activity Monitor under the Network tab on Mavericks. Alternatively, you could run fs_usage in the terminal as root and that will show you which process is using the network connection (along with every file system hit too).
