FnordMetric allows you to chart events in real time. This is great for keeping track of user activity in your Rails app as demonstrated in this episode.

Interesting screencast. Could it be a mountable engine? Is possible to protect it with authentication?
There is a little information about doing so here: https://github.com/paulasmuth/fnordmetric/issues/60
I've just now asked for an example / gist

Does anyone know whether and if so how it's possible to use fnordmetric on heroku?

Yes you can.
This pull request enabled Fnordmetric to run as a rack app.

However, keep an eye in your Redis Store. Depending on the amounts of events you might end running out of space in your Redis REALLY QUICKLY.
I ate a 100MB Redis Store in just 3 days (Hight traffic website).
I see that fnordmetric is namespacing redis. Can this be easily integrated with resque using the same redis instance?
I am going to integrate the event tracking into my system. Will this lead to some performance issue when real time access increased sharply?
Can anyone describe how FnordMetric compares/contrasts to graphite-statsd??
Does anyone know if / how / links to an API or such that will allow me to pull for instance just one graph into my Rails app, for example for showing number of visits to a user's page on that user's dashboard?
How expensive would this solution be if you have 100,000+ interactions a day on your site? Does this scale well?
I am trying to install fnordmetric gem in my rails application. I installed the gem with this command sudo gem install fnordmetric. Gem is installed but i am getting this error when i run the server through script/server
invalid gemspec in illformed requirement in /usr/local/lib/ruby/gems/1.8/specifications/fnordmetric-1.0 gemspec
and in /code/ts-delayed-delta/ruby/gems/1.8/specifications/fnordmetric-1.0 gemspec
I updated the gems using sudo gem update --system. Still i am getting the same error.
Can anyone suggest me how to overcome this problem..?
Thank you in advance
Where can I find the example of the fnordmetric.rb file? The link is not to the file.
Could you put this on GitHub?
I am interested in using this in a multi-tenant app. There is a hint at the fnordmetric.io site "Namespaces can be used to separate users if you are deploying FnordMetric as a white-label solution to your customers." I'd like to know how to do this dynamically in a running app so when a user creates an account an instance of fnordmetric is also setup and configured for him/her. I would appreciate any pointers on this.
did you find and answer for that? I'm also trying to find a good solution for this problem
@bakki, did you find and answer for that? I'm also trying to find a good solution for this problem
I watched the video and followed all the instruction of Fnordmetric railscast.
install redis
redis-server /usr/local/etc/redis.conf
Redis is working fine on my local(Ubuntu 12.04)
gem install fnordmetric
Installed successfully.
Created new fnordmetric.rb file
When I run ruby fnordmetric.rb on terminal
$ ruby fnordmetric.rb
./fnordmetric.rb:3: uninitialized constant FnordMetric (NameError)
from fnordmetric.rb:1:in `require'
from fnordmetric.rb:1
I am getting above error.
Please help me to fix this issue and get it working
Thanks in advance
On rubygems that latest update is June 2013 and it is presently at a failing rating on GitHub. Is this something of a concern or can this gem still be used safely in production?
Cool! Thanks guys!
Is this is available on github ?
