A silly example app configured to send runtime and host metrics to Honeycomb.

An example application that sends metrics & traces to Honeycomb

• See golang server code in server/main.go.
• See OpenTelemetry Collector configuration in ./config/otelcol-config.yaml

Running this example locally

1. Install dependencies. On MacOS:

brew install go ansible entr
brew install --cask multipass

2. Create a provision/cloud-init.yaml file with a valid SSH public key in it so you can connect to your servers:

ssh_authorized_keys:
  - ssh-rsa abcabc_my_ssh_key [email protected]
package_update: true

3. Create local virtual machines:

./provision/provision.bash

Hacky note: the scripts from this point forward assume that it's possible to connect to local vms as vm1, vm2, and lb. To get everything working you'll need to create aliases from those names to the VM IP addresses in your ~/.ssh/config file. You can find those IP addresses by running multipass list.

4. Deploy to your hosts (you'll need a Honeycomb API key for this)

HNY_API_KEY=????? ./deploy.bash

5. Server should be running on the lb host at port 80
