This is really cool and I might have found a very good use for it just by looking at it.
One thing though: IMHO it should also be possible to dispatch events over UDP as often times you don't care that much whether the event is actually logged or not.
You do however care about the responsiveness of the application that's doing the logging and you really don't want it to hang while the logging server is being slow with its tcp handshake.
Thankfully, this is open source and n github, so I can fix this. Expect a pull request tomorrow-ish
Awesome! At Fileboard we use lots of third party tools (Mixpanel/KISSMetrics) to keep track of user metrics and stuff but there are always things where these tools just can't provide us with answers. Especially since we are an ipad app and most of these things are designed for web app usage.
I didn't want to roll my own solution for keeping track of the "extra" stuff but having seen this I am definatly going to give it a spin and see wether it helps us get more grip on user behavior.
Hmm was just thinking. Could I also use this for tracking internal transactions? I am still looking for a good solution to get insight into the statistical/live transactions that my system is handling.
User behavior is great but since our solution spans multiple servers I would love to be able to see what happens say for ex. when somebody wants to send a e-mail message with dropbox attachment through our system.
Also tracking the nr of errors being raised would be mighty interesting. I know there are third party solutions out there that solve part of the equation but having this data in one place sounds pretty interesting.
Yes, thats exactly what we do with it. We use it to track (among other things) sent/read messages, created ratings, , signups and sales.
You can define your own metrics/gauges very easily. Have a look at "doc/ulm_stats.rb" or contact me on skype ("paulasmuth") if you run into any questions or issues :)
I'm a product manager/developer and find myself wanting to know the real-time and historical usage of the products I manage so that I can proactively address issues and prioritize future development. Some kind of combination of google analytics for the client side and NewRelic (or http://amon.cx) for the server side.
I'm going to play with this over the holidays to see if it would help me with that.
Really clean design, love it. I can imagine this would be really cool with something like a chat application displaying messages/sec, users online, messages read, stuff like that.
Also an excellent showcase of a use of redis.
EDIT: And in case you missed it first time around like I did, here's a link to a screencast of it in action: http://www.screenr.com/KiJs
I only took a quick glance through the source, but what's with the MongoDB dependency? Is there a chance that what you're using it for could be replaced with Redis? I already use Redis, but I'm hesitant to introduce yet another database into my stack unless it's absolutely necessary.
Cool :) We've actually been using it in production for a few months now.
You should have a look at "doc/ulm_stats.rb" - that's the configuration from the screenshots and screencasts.
If you have any issues or questions you can always contact me on skype ("paulasmuth")...
