# Prometheus remote write backend ## Prerequisites To use the prometheus remote write API with [storage providers](https://prometheus.io/docs/operating/integrations/#remote-endpoints-and-storage) [protobuf](https://developers.google.com/protocol-buffers/) and [snappy](https://github.com/google/snappy) libraries should be installed first. Next, Netdata should be re-installed from the source. The installer will detect that the required libraries and utilities are now available. ## Configuration An additional option in the backend configuration section is available for the remote write backend: ```conf [backend] remote write URL path = /receive ``` The default value is `/receive`. `remote write URL path` is used to set an endpoint path for the remote write protocol. For example, if your endpoint is `http://example.domain:example_port/storage/read` you should set ```conf [backend] destination = example.domain:example_port remote write URL path = /storage/read ``` `buffered` and `lost` dimensions in the Netdata Backend Data Size operation monitoring chart estimate uncompressed buffer size on failures. ## Notes The remote write backend does not support `buffer on failures` [](<>)
