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.

Thanos Query

Thanos Query is another of the most fundamental Thanos components. Without it, there’s not much point to Thanos Sidecar. It provides both a web UI and an API that are used to execute PromQL queries across multiple data sources (for example, Prometheus via Thanos Sidecar, metrics in object storage via Thanos Store, and so on).

The web UI will feel familiar to anyone who has used the Prometheus web UI since their functionality and UX are essentially equivalent. The query API is also 100% PromQL compliant and therefore can be used as a Prometheus-typed data source in Grafana. In practice at companies I’ve been at, we’ve even tended to use Thanos Query as our default data source in Grafana.

Thanos Query works by connecting to one or more endpoints that implement Thanos’s gRPC-based StoreAPI. Endpoints can be specified via the repeatable --endpoint flag. This flag supports both static definitions (for example, --endpoint=192.168.1.2:10901)...
