110-opentelemetry-php-app

This cookbook runs multiple containers on a Docker host. A container of the Apache http server exposes a web listener to serve some PHP samples and another container continuously connects to it to generate traffic. The PHP samples are manually instrumented with OpenTelemetry and different exporters, OTLP http and also Zipkin. The Aternity OpenTelemetry Collector container collects all traces, every span without sampling, and sends the spans to the Aternity SaaS backend.

Prerequisites

1. an Aternity APM account (SaaS)
2. a Docker host, for example Docker Desktop

Step by Step

Step1. Get your CustomerID & SaaS Analysis Server Host details from the Aternity APM webconsole

Navigate to Aternity APM (for example https://apm.myaccount.aternity.com) > Agents > Install Agents:

1. Find your CustomerID, for example 12341234-12341234-13241234
2. Grab SaaS Analysis Server Host, for example agents.apm.myaccount.aternity.com

Those information are required to activate the Aternity OpenTelemetry Collector container, passing via the environment variable SERVER_URL.

Step2. Start the containers

Download a local copy of the files of this cookbook, for example store them in the folder Tech-Community/110-opentelemetry-php-app

|- docker-compose.yaml
|- src
    |- index.php
    |- SampleOTLPhttpExporter.php
    |- SampleZipkinExporter.php

Start the containers using the docker-compose.yaml, for example with Bash:

cd Tech-Community/110-opentelemetry-php-app

# Configure the environment variables for the Aternity OpenTelemetry Collector
export ATERNITY_SAAS_SERVER_HOST="agents.apm.myaccount.aternity.com"
export ATERNITY_CUSTOMER_ID="12341234-12341234-13241234"

docker-compose up

or with PowerShell:

cd Tech-Community/110-opentelemetry-php-app

# Configure the environement variable for the Aternity OpenTelemetry Collector
$env:ATERNITY_SAAS_SERVER_HOST="agents.apm.myaccount.aternity.com"
$env:ATERNITY_CUSTOMER_ID="12341234-12341234-13241234"

docker-compose up

Step3. Try the app

Browse the local urls

• http://localhost:8110
• http://localhost:8110/SampleOTLPhttpExporter.php
• http://localhost:8110/SampleZipkinExporter.php

Step4. Open the Aternity APM webconsole to visualize and analyze the traces collected for every transaction

Notes

Stop the app and all the containers

Press CTRL + C in the shell where it is running.

Or in a shell, go to the folder where you keep the docker-compose.yaml and run:

docker-compose down
