PR Description

Influx receiver that converts to OTEL
Can be used in conjunction with otelcol.exporter.prometheus to further convert influx to prom format.

ex alloy config:

logging {
  level = "debug"
}

// Configure the InfluxDB receiver to collect and forward metrics
otelcol.receiver.influxdb "influxdb_metrics" {
  endpoint = "localhost:8086"  //InfluxDB metrics ingestion endpoint
  output {
    metrics = [otelcol.exporter.prometheus.influx_output.input]  // Forward metrics to Prometheus exporter
  }
}

// Configure the Prometheus exporter to send the metrics to Mimir
otelcol.exporter.prometheus "influx_output" {
  forward_to = [prometheus.remote_write.mimir.receiver]  // Forward metrics to Prometheus remote write (Mimir)
}


prometheus.remote_write "mimir" {
  endpoint {
    url = "https://prometheus-prod-13-prod-us-east-0.grafana.net/api/prom/push"

    basic_auth {
