AppPerf (Application Performance Monitoring)
Demo
There is an instance of this running at https://app-perf.herokuapp.com. Please note that there is a low data retention setting so that it doesn't go over the allowed total row count with Heroku.
To log in use the email address of "user@example.com" and a password of "password".
More images are at the bottom.
NOTE: This application is in extremely beginning stages and I am still working out flows and learning the data model. I will be cleaning code up as I go.
This is a application monitoring app. I am trying to build an open source, easy to setup, performance monitoring tool.
Setup
Setup should be striaghtforward and easy. We use foreman to manage processes. Begin by running the setup script:
./bin/setup
This should create and setup the database and any other needed services/apps. Then to start everything up, run foreman:
bundle exec foreman start
Navigate to http://localhost:5000. This application is setup to report to itself so you can begin seeing information immediatetly!
Using Other databases
SQLite has some limitation with concurrency in this app, as well as various date functions used for reporting. If you would rather test against postgresql (Mysql to come), you can run the following command to create a local development database running on port 5443 (Must have postgresql installed):
./bin/setup_psql
Note: Don't forget to update your config/database.yml file.
Adding Applications
App Perf will automatically detect new applications that are posting data and display them in the Applications page. From there you can go to each individual application to view the performance metrics.
In order to monitor an application, you have to add the Ruby Agent gem to the Gemfile:
gem "app_perf_rpm", :git => "git@github.com:randy-girard/app_perf_rpm"
Once you have add the gem, Add the following lines to your project (or in an initializer):
require 'app_perf_rpm'
AppPerfRpm.configure do |rpm|
rpm.license_key = "License Key"
rpm.application_name = "Application Name"
end
You can get your license key by visiting the Applications tab and clicking the "New Application" button.
How the data model works
Adding metrics to App Perf is as simple as posting data to the following endpoint:
POST http://domain/api/listener/:protocol_version/:license_key
Currently the only protocol version supported is 2. License key is generated when you create a new user account. There is a default one that is used for testing in the .env.development file.
TODO: Add examples of how to submit data.
Contributing to the App Perf Ruby Agent
Clone the github project at https://github.com/randy-girard/app_perf_rpm somewhere locally, then run the following command to force bundler to look at that specific path:
bundle config local.app_perf_rpm /path/to/local/app_perf_rpm
To remove this configuration, run the following command:
bundle config --delete local.app_perf_rpm
