Is it Observable

Episode : WHat is Odigo

This repository contains the files utilized during the tutorial presented in the dedicated IsItObservable episode related Odigos.

This repository showcase the usage of Odigos with :

• The hipster-shop
• The OpenTelemetry demo
• Dynatrace

We will send all Telemetry data produced by Odigos to Dynatrace.

Prerequisite

The following tools need to be install on your machine :

• jq
• kubectl
• git
• gcloud ( if you are using GKE)
• Helm

Deployment Steps in GCP

You will first need a Kubernetes cluster with 2 Nodes. You can either deploy on Minikube or K3s or follow the instructions to create GKE cluster:

1.Create a Google Cloud Platform Project

PROJECT_ID="<your-project-id>"
gcloud services enable container.googleapis.com --project ${PROJECT_ID}
gcloud services enable monitoring.googleapis.com \
    cloudtrace.googleapis.com \
    clouddebugger.googleapis.com \
    cloudprofiler.googleapis.com \
    --project ${PROJECT_ID}

2.Create a GKE cluster

ZONE=europe-west3-a
NAME=isitobservable-odigos
gcloud container clusters create "${NAME}" --zone ${ZONE} --machine-type=e2-standard-8 --num-nodes=2

Getting started

Dynatrace Tenant

1. Dynatrace Tenant - start a trial

If you don't have any Dyntrace tenant , then i suggest to create a trial using the following link : Dynatrace Trial Once you have your Tenant save the Dynatrace tenant url in the variable DT_TENANT_URL (for example : https://dedededfrf.live.dynatrace.com)

DT_TENANT_URL=<YOUR TENANT Host>

2. Create the Dynatrace API Tokens

Create a Dynatrace token with the following scope ( left menu Acces Token):

• ingest metrics
• ingest OpenTelemetry traces
• ingest logs

Save the value of the token . We will use it later to store in a k8S secret

DATA_INGEST_TOKEN=<YOUR TOKEN VALUE>

2.Clone the Github Repository

https://github.com/isItObservable/odigos
cd odigos

3.Deploy most of the components

The application will deploy the entire environemnt:

chmod 777 deployment.sh
./deployment.sh   --dthost "${DT_TENANT_URL}" --dttoken "${DATA_INGEST_TOKEN}" 

5.Configure Odigo

1. From the ui:

kubectl port-forward svc/odigos-ui 3000:3000 -n odigos-system

Select the namespace Hipster-shop and click on "everything in this namespace"

2. From the cmdline

1. Instrument the hipster-shop namespace

to let odigos instrument the hipster-shop we need to label the namespace :

kubectl label ns hipster-shop odigos-instrumentation=enabled

2. Create the Dynatrace destination

to create the dynatrace destination , we first need to create the dynatrace secret in the odigos-system
