browser-breakdown.md

This is a breakdown of the top 100 browsers that bugsnag-js saw during 2014-01-08Z.

It's interesting to see that, for our customers at least, Safari (28%) beats Chrome (26%) by a small margin (maybe it's counting iPhone too); with IE (20%) slightly behind. Firefox (12%) is lagging sorely.

Raw percentages for the most popular 100 browsers (about 95% of total), the remainder were a total mess.

user-agent.rb

# 1. Get a list of the logfiles you want to analyze:
# $  s3cmd ls s3://examplelogs/cf-logs/ABCDEF1234567890.2014-01-08 | sed 's/.*s3/s3/' | tee /tmp/logfiles
#
# 2. Extract the CGI-escaped user-agent strings:
# $  cat /tmp/logfiles | xargs -I{} s3cmd get {} - | gunzip | cut -d $'\t' -f 11 | tee /tmp/browsers
#
# 3. Parse them and add them up (requires gem install useragent)
# $  ruby analyze.rb <(cat /tmp/browsers | sort | uniq -c) | tee /tmp/analysis
#
