See how fast is rendering in your Ruby on Rails app. Based on information from logs. Provides you a picture of how often renders and how fast renders your views.
You can see columns:
- Type - type of file (partial or view = P or V)
- View - name of view
- Count - number of renders
- Avg - average time of rendering (in milliseconds)
- Max - maximum time of rendering
- Min - minimum time of rendering
Could be installed as standalone (without adding to Gemfile).
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install log_analyzer
After installation run in console command
log_analyzer -f log/development.log. You can change the file or sorting (time, count, name).
log_analyzer log/development.log -s count
log_analyzer production.log -csv
log_analyzer production.log -pdf
log_analyzer -f log/production.log -s name
log_analyzer -f log/production.log -s time -f v
log_analyzer -f log/production.log -s rtime -f v
log_analyzer -file log/production.log -sort count
log_analyzer -file log/production.log -sort count -filter view
log_analyzer -file log/production.log -sort count -filter partial
log_analyzer -file log/production.log -sort time -filter p
log_analyzer development.log -csv -s time -f p
log_analyzer development.log -xls -s time -f p
log_analyzer log/production.log -pdf --short
log_analyzer -file log/production.log --short
Based on results you can get an idea what to optimize. For example optimizing most often rendering view could give huge benefit. Now with this tool you can find out what are the numbers.
Based on the observations I suggest to run this tool for files less than 1Gb. If you have enough RAM - download the log file to local machine and then run the tool.
After checking out the repo, run
bin/setup to install dependencies. Then, run
rake spec to run the tests. You can also run
bin/console for an interactive prompt that will allow you to experiment.
To install this gem on your local machine, run
bundle exec rake install. To release a new version, update the version number in
version.rb, and then run
bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the
.gem file to rubygems.org.
