This repository is the repackaging of node_exporter as an Opentelemetry Collector Receiver.
(Despite the name, it's a receiver)
Opentelemetry Collector already has a component to scrape node metrics. First of all, I recommend to check hostmetrics.
node_exporter receiver is intended to be used when you want to reuse existing dashboards and alerting rules built for Prometheus node_exporter (or just need one of the collectors).
Unfortunately it's not easy to reuse node_exporter because the usage of global variables and flag parsing.
Grafana Alloy had a similar problem, and they created a fork: https://github.com/prometheus/node_exporter/pull/2812
Here, I use different approach. The collector directory is vanilla node_exporter, only the import path of the kingpin library is replaced.
That can make it easer to keep up to date with the original node_exporter.
Can be configured like the original node exporter using the flags field in configuration.
Example:
receivers:
nodeexporter:
interval: 10s
flags:
collector.cpu: "false"
...
service:
pipelines:
metrics:
receivers: [nodeexporter]
exporters: [debug]
This is just a repackage. Kudos for the original contributors (can be found in the current Git history).

Functions ¶
func NewFactory ¶
NewFactory creates a factory for tailtracer receiver.
Types ¶
type NodeExporterReceiver ¶
type NodeExporterReceiver struct {
// contains filtered or unexported fields
}
type Option ¶
type Option interface {
// contains filtered or unexported methods
}
Option sets producer option values.
func WithGatherer ¶
func WithGatherer(gatherer prometheus.Gatherer) Option
WithGatherer configures which prometheus Gatherer the Bridge will gather from. If no registerer is used the prometheus DefaultGatherer is used.
type Producer ¶
type Producer struct {
// contains filtered or unexported fields
}
func NewMetricProducer ¶
NewMetricProducer returns a metric.Producer that fetches metrics from Prometheus. This can be used to allow Prometheus instrumentation to be added to an OpenTelemetry export pipeline.
