14	14	The results are not sorted (by date). This can be done by: sort results > results.sorted. The results output format is a SSV (Space Separated Values) file organized in lines (end of line is \n). A result line starts by a timestamp (e.g. 2011-02-13T21:40:00) and numbers detailing the Apache/Nebulous activity during the 10 minutes following the timestamp (that is what happened between 2011-02-13T21:40:00 and 2011-02-13T21:49:59+(1-epsilon)). The first number is the total of Nebulous related messages in the access_log; the second one is the number of entries in the error_log; the third is the number of Nebulous create requests messages, the fourth is the number of find_instance requests; the fifth is the number of delete requests; the sixth is the number of fail_stat requests; the seventh of stat requests; the eighth the Nebulous unknown request (hence the first number is the sum of columns 3 to 8); the last/ninth column is the count of non-Nebulous requests.
