-# 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`
