An output plugin to submit Prometheus Metrics using the remote write protocol
The prometheus remote write plugin allows you to take metrics from Fluent Bit and submit them to a Prometheus server through the remote write mechanism.
Important Note: The prometheus exporter only works with metric plugins, such as Node Exporter Metrics
Key | Description | Default |
---|---|---|
The Prometheus remote write plugin only works with metrics collected by one of the from metric input plugins. In the following example, host metrics are collected by the node exporter metrics plugin and then delivered by the prometheus remote write output plugin.
The following are examples of using Prometheus remote write with hosted services below
With Grafana Cloud hosted metrics you will need to use the specific host that is mentioned as well as specify the HTTP username and password given within the Grafana Cloud page.
With Logz.io hosted prometheus you will need to make use of the header option and add the Authorization Bearer with the proper key. The host and port may also differ within your specific hosted instance.
With Coralogix Metrics you may need to customize the URI. Additionally, you will make use of the header key with Coralogix private key.
