OddEye Local Proxy

OddEye Proxy is a small and high performance proxy application that act as moc OddEye API server for agents running in internet restricted environments.
It accepts requests from oe-agent, stores metrics in memory or RabbitMQ and push it to real OddEye API servers.


OddEye local proxy is a simple Go application, which is ditributed as source code or pre-compilled, single file binary. Binaries are hosted at releases section, please download and sun the latest version for Linux , it does not have any external dependencies

Build from soure

To build OddEye proxy from source, you need Go sdk and binaries . Building from source fo Linux is easy with only few simple steps.

git clone https://github.com/oddeyeco/oe-go-proxy.git
cd oe-go-proxy 
export GOPATH=`pwd`
go get github.com/streadway/amqp
go get gopkg.in/ini.v1
go build -o oe-go-proxy src/start.go 
mkdir /usr/local/oe-go-proxy

mv oe-go-proxy /usr/local/oe-go-proxy/
mv src/config.ini /usr/local/oe-go-proxy/
cd /usr/local/oe-go-proxy/
chmod 755 oe-go-proxy

We recommend executing oe-go-proxy via system.d. Below are few simple steps to make systemd service and run it OddEye proxy does not need any special privileges so it is safer to run it a regular system user.

useradd -r -s /bin/false oddeye

Create /etc/systemd/system/oe-go-proxy.service file with following content


User = oddeye
Group = oddeye
ExecReload=/bin/kill -HUP $MAINPID


Reload systemd and start service.

systemctl daemon-reload 
systemctl enable oe-go-proxy.service
systemctl restart oe-go-proxy.service


OddEye proxy uses simple and intuitive config file which ships with a source. Example config is below. config file should be in same folder as oe-go-proxy binary. Just set up few parameters and run the service.

listen :
remote : https://api.oddeye.co/oddeye-barlus/put/tsdb
dispatchers : 20
queuesize : 5000000
internalqueue : false

serverauth : true
serveruser : admin
serverpass : $ecretPaSs

clientauth : true
clientuser : admin
clientpass : $ecretPaSs

rabbiturl : amqp://admin:admin@localhost:5672/
rabbitqueue : oemetrics

enabled : true
user: admin
pass: $ecretPaSs

OddEye proxy support caching of messages in memory and RabbitMQ server. If due to any reason proxy will lose connection to main OddEye servers it will cache queuesize amount of messages in memory and if you use RabbitMQ you can cache as many messages and you have disk space for RabbitMQ.

If you prefer not to use RabbitMQ, then OddEye proxy will cache queuesize amount of messages. Local queue is FIFO aof if there are more than queuesize, old one will be replaced with new messages.

Install RabbitMQ

Now we need to install RabbitMQ. If you already have RabbitMQ installation at your environment, you can skip this steps.

Debian / Ubuntu

apt-get install rabbitmq

CentOS / Redhat

yum -y install epel-release
yum -y update
yum -y install erlang socat
wget https://www.rabbitmq.com/releases/rabbitmq-server/${VERSION}/rabbitmq-server-${VERSION}.noarch.rpm
rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
rpm -Uvh rabbitmq-server-${VERSION}.noarch.rpm
systemctl start rabbitmq-server
systemctl enable rabbitmq-server

Enable RabbitMQ web console

rabbitmq-plugins enable rabbitmq_management

Create admin user

rabbitmqctl add_user admin StrongPassword
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
