# etcd vs node_exporter

etcd and node_exporter share 3 technologies: Prometheus, github.com/coreos/go-systemd/v22, and github.com/prometheus/client_model. Both are written in Go.

- [etcd-io/etcd](https://seerepo.com/r/etcd-io/etcd): Distributed reliable key-value store for the most critical data of a distributed system
- [prometheus/node_exporter](https://seerepo.com/r/prometheus/node_exporter): Exporter for machine metrics

## What they share and what sets them apart

- In common: Prometheus, github.com/coreos/go-systemd/v22, github.com/prometheus/client_model
- Only in etcd: net/http, go.etcd.io/etcd/api/v3, go.etcd.io/bbolt, github.com/olekukonko/tablewriter, github.com/cheggaaa/pb/v3, github.com/golang-jwt/jwt/v5, go.uber.org/zap, OpenTelemetry, go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc, go.opentelemetry.io/otel, go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc, go.opentelemetry.io/otel/sdk, gopkg.in/natefinch/lumberjack.v2
- Only in node_exporter: howett.net/plist, github.com/prometheus/common

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
