William Hegedus

William Hegedus has worked in tech for over a decade in a variety of roles, culminating in site reliability engineering. He developed a keen interest in Prometheus and observability technologies during his time managing a 24/7 NOC environment and eventually became the first SRE at Linode, one of the foremost independent cloud providers. Linode was acquired by Akamai Technologies in 2022, and now Will manages a team of SREs focused on building the internal observability platform for Akamai's Connected Cloud. His team is responsible for a global fleet of Prometheus servers spanning over two dozen data centers and ingesting millions of data points every second, in addition to operating a suite of other observability tools. Will is an open source advocate and contributor who has contributed code to Prometheus, Thanos, and many other CNCF projects related to Kubernetes and observability. He lives in central Virginia with his wonderful wife, four kids, three cats, two dogs, and a bearded dragon.

Sending metrics to Prometheus with the OpenTelemetry collector

At the time of writing, sending data to Prometheus over OTLP is still considered an experimental feature. In fact, the functionality came out during the process of writing this book (in Prometheus version 2.47.0), so we’ll need to upgrade the version of Prometheus we’ve been running so far in order to enable support for it.

Configuring Prometheus

To support the OTLP receiver on Prometheus, we need to adjust our Helm chart to install a newer version of Prometheus and add a --enable-feature=otlp-write-receiver flag to the Prometheus process. Additionally, to avoid any complications inherent in pushing data to multiple Prometheus replicas, we’ll scale back down to a single replica.

The Helm values file we’ll use looks like the following:
