    Hi,
    I do have a strange messages in Console it says "disk writes_2017-02-04-004442" and it has poping up 2017-02-04 and 2017-02-05.
    It seems that it has start coming after I did re-install macOS I did that 2015-02-03.

    It do show up in console under "System Reports" and the file name starts at "disk writes_"
    The full names of the reports is:
    "disk writes_2017-02-04-004442_Robins-MacBook-Pro"
    "disk writes_2017-02-05-003337_Robins-MacBook-Pro"

    The beining of the log created 2017-02-04


    And here is the beginning of the log created 2017-02-05.

    Here is the complete log files, you need to download them as it's to long to copy / past here.
    I have made them in PDF file.

    TL;DR I think it's harmless. I had a look in my console, and sure enough had a couple of entries.

    After some googling and futzing around in Terminal, these are apparently reports written by a daemon (i.e. a background process) called systemstatsd. It kicks off every now and then, to collect some statistics.

    I was surprised to see that you can actually view the results in a human-readable format. Open a terminal and on the prompt, type:

    $ sudo systemstats | less

    It prints a pretty nice bunch of usage numbers on disk activity, wifi activity et cetera. My guess is, that it can be used to diagnose problems that occur in the field. For instance, suppose a customer brings in a MacBook Pro with the message that the battery life is terrible. Then the genius could take a look at this report. Under the header "ranked battery usage", it says for my 2016 15" MBP:

    CPU Time: 00:06:53 (62.7%)
    00:01:07 (10.2%) 97342 org.mozilla.firefox
    00:00:57 (8.6%) 11882 com.crashplan.engine
    00:00:56 (8.6%) 106 com.apple.sandboxd
    00:00:33 (5.1%) 21717 com.apple.WindowServer
    00:00:27 (4.1%) 2322 com.crystalidea.MacsFanControl


    That's pretty interesting :)

    So you have the same log files under system report in console?

    I have deleted the log files now and I'll se if it pops up again.
