Change CSV column names

[heyman]

Since we're changing the CSV columns (#1316) we should also consider changing the column names to be more consistent.

Here are the current column names for the history CSV

Timestamp
User count
Type
Name
# requests
# failures
Requests/s
Requests Failed/s
Median response time
Average response time
Min response time
Max response time
Average Content Size
50%
66%
75%
80%
90%
95%
98%
99%
99.9%
99.99%
99.999
100%

Column names for the request stats CSV

Type
Name
# requests
# failures
Median response time
Average response time
Min response time
Max response time
Average Content Size
Requests/s
Requests Failed/s
50%
66%
75%
80%
90%
95%
98%
99%
99.9%
99.99%
99.999
100%

Column names for the failures CSV

Method
Name
Error
Occurrences

Column names for the exceptions CSV

Count
Message
Traceback
Nodes

For the use-case where people use the CSV data programmatically, I guess it would make sense to use more variable like column names such as user_count, request_count, requests_per_second, response_time_99, etc.

However there's also the use-case of simply importing the CSV into a spreadsheet, and it that case more human readable column names makes more sense.

What do you think?

I'm definitely ok with changing, but I'm not personally invested in it and dont want it to block 1.0 release :)

I've decided to change the naming to be more consistent, and to append a "Total " prefix to the columns in the history CSV that contains stats for the whole (total) test run. The new column names for the history CSV will be:

Timestamp
User Count
Type
Name
Requests/s
Failures/s
50%
66%
75%
80%
90%
95%
98%
99%
99.9%
99.99%
99.999%
100%
Total Request Count
Total Failure Count
Total Median Response Time
Total Average Response Time
Total Min Response Time
Total Max Response Time
Total Average Content Size
