Kool Monkey is an Open and Distributed Web monitoring system that collects metrics related to web site perfomances, such as Response Time, Site Uptime and Network Roundtrip.
Today we observe a proliferation of web monitoring tools, and each one of those is usually in one of the 2 following categories:
Both these types of solution tend to be expensive, and will typically lack support for any but the most common cases.
With any of the existing commercial solutions you're then limited by either the Pricing model, which makes it suitable for establised enterprise businesses, or the provider infrastructure, which generally has coverage of the most common / high internet density areas, and leave out the biggest portion of the globe.
The vast majority of the current providers will offer you agents in the Bay Area, but seldomly you will be offered the ability to monitor from Chiapas, Hawaii or Siberia.
In order to overcome both these limitations we decided to build - and will continue building - Kool Monkeys.
The way Kool Monkeys tries to be a completely new approach to the Web Monitoring problem is by being both Distributed and Open.
The idea behind Kool Monkey is that any user will operate one or more agents.
The agent is free to download, and can run on Linux and OSX with no major
issues.
Once each agent is registered under the account of the user operating it, and its location documented, it will be available for performing any web performance test against any possible web page from that specific location.
The key advantage here is that in order to operate the service at scale, we don't need to set up an expensive infrastructure for hosting agents in various locations across the world. Instead we just need to make the sevice useful for our users and provide incentives for them to run one or more agents. More on that later.
All of the metrics collected by all the agents are stored in a central location, and can be shared with all the users of the platform.
Using the distributed potential of Kool Monkey, you will be able to answer questions such as:
name a remote location here?Without the need to invest a lot of capital in setting up dedicated infrastructure. The only thing you will have to do will be to share your agents with the community.
Kool Monkey is both an Open Source project and an Open Service. The source code for Kool Monkey will be always available though GitHub or any alternative service in the future.
Additionally, we'll be operating an Open Service which will soon be open to the whole community of people interested in Web Performance Measurements and that requires high geographical granularity without prohibitive service fees.
The way this is going to work is very simple:
fair usage slots you will get in order to use the global networkBy using such a model, every user is encouraged to operate as many agents as possible, which will give them
access to more monitoring slots on the global platform. What goes around, comes around is a great way to
summarize the core concept of the service!
The idea behind Kool Monkeys is to create the largest distributed network for Web Monitoring in the world. By doing that we'll be able to open up various possibilities for the future:
State of the Internet by providing up to date comprehensive coverage of
how the current trends in Web performance are evolvingThe project started in the Gopher Gala 2016 (22-24 of January) based on particular needs of the participants.
We are currently doing the management on the project in trello, so feel free to check it out and see what we have done and what we are planning to do.
Kool Monkey is distributed under the terms of the GPLv3
A live demo is availale at this URL. It might be unavailable from time to time, and will be updated regularly. Also, all the stored data is to be considered volatile.
This project has three important elements: the agent, the server and the frontend.
The agent is in charge of doing the actual measurements of the webpage. It's developed in Go as a daemon that comunicates with the server in order to obtain the urls to monitor with some parameters (when to start and end the monitoring, the periodicity of the metrics, what metrics to run, …) and send back the actual metrics obtained.
The server is a central go application that manages the work between the different agents, stores in db the results and comunicates with the front end in order to obtain the user requests and show back the results collected from the agents.
The frontend is where the user can request a new monitoring and see the different information that has been collected in a graphical and easy way.
As you have seen, the development of the project is in Go, so we have provided some Makefiles in order to work with the code. These Makefiles are not only useful to develop in the project, but to build rpms packages from the source.
We have also integrated the project with Travis to run the tests, build the rpms and deploy into production both the server part (metrics collection and web frontend) and the agents, so it's become quite easy to build and deploy the project.
The current status of travis is 
In order to build and run the project you will require the following:
If you want to set up Kool Monkeys for local development, just clone the repo and go through the following steps:
Build the project by calling:
make
Start up the dev environment by calling:
make start-environment
Start the Kool Monkeys server as follows:
./bin/kool-server -conf dev-env/conf/kool-server.conf
Start the monitoring agent:
./bin/kool-agent
