Prometheus Remote Write Exporter

This Exporter sends metrics data in Prometheus TimeSeries format to Cortex or any Prometheus remote write compatible backend.

Non-cumulative monotonic, histogram, and summary OTLP metrics are dropped by this exporter.

The following settings are required:

endpoint: protocol:host:port to which the exporter is going to send traces or metrics, using the HTTP/HTTPS protocol.

The following settings can be optionally configured:

namespace: prefix attached to each exported metric name.
headers: additional headers attached to each HTTP request. If X-Prometheus-Remote-Write-Version is set by user, its value must be 0.1.0
insecure (default = false): whether to enable client transport security for the exporter's connection.
ca_file: path to the CA cert. For a client this verifies the server certificate. Should only be used if insecure is set to false.
cert_file: path to the TLS cert to use for TLS required connections. Should only be used if insecure is set to false.
key_file: path to the TLS key to use for TLS required connections. Should only be used if insecure is set to false.
timeout (default = 5s): How long to wait until the connection is close.
read_buffer_size (default = 0): ReadBufferSize for HTTP client.
write_buffer_size (default = 512 * 1024): WriteBufferSize for HTTP client.

Example:

exporters:
prometheusremotewrite:
 endpoint: "http://some.url:9411/api/prom/push"

The full list of settings exposed for this exporter are documented here with detailed sample configurations here.
