-# OpenTSDB with HTTP
-
-Netdata can easily communicate with OpenTSDB using HTTP API. To enable this channel, set the following options in your
-`netdata.conf`:
-
-```conf
-[backend]
-    type = opentsdb:http
-    destination = localhost:4242
-```
-
-In this example, OpenTSDB is running with its default port, which is `4242`. If you run OpenTSDB on a different port,
-change the `destination = localhost:4242` line accordingly.
-
-## HTTPS
-
-As of [v1.16.0](https://github.com/netdata/netdata/releases/tag/v1.16.0), Netdata can send metrics to OpenTSDB using
-TLS/SSL. Unfortunately, OpenTDSB does not support encrypted connections, so you will have to configure a reverse proxy
-to enable HTTPS communication between Netdata and OpenTSBD. You can set up a reverse proxy with
-[Nginx](../../docs/Running-behind-nginx.md).
-
-After your proxy is configured, make the following changes to `netdata.conf`:
-
-```conf
-[backend]
-    type = opentsdb:https
-    destination = localhost:8082
-```
-
-In this example, we used the port `8082` for our reverse proxy. If your reverse proxy listens on a different port,
-change the `destination = localhost:8082` line accordingly.
