 - [Fast query engine](https://medium.com/@valyala/when-size-matters-benchmarking-victoriametrics-vs-timescale-and-influxdb-6035811952d4). It excels on heavy queries over thousands of metrics with millions of metric values.
 - The same remote storage URL may be used by multiple Prometheus instances collecting distinct metric sets, so all these metrics may be used in a single query (aka `global querying view`). This works ideally for multiple Prometheus instances located in different subnetworks / datacenters.
 - Accepts data in [InfluxDB line protocol](https://docs.influxdata.com/influxdb/v1.7/write_protocols/line_protocol_reference/), so [Telegraf](https://www.influxdata.com/time-series-platform/telegraf/) and other influx-compatible agents may send data to VictoriaMetrics.
-- [Single-server VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics/releases) accepts data in [Graphite plaintext protocol](https://graphite.readthedocs.io/en/latest/feeding-carbon.html#the-plaintext-protocol) if `-graphiteListenAddr` is set.
+- [Single-server VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics/releases) accepts data in [Graphite plaintext protocol](https://graphite.readthedocs.io/en/latest/feeding-carbon.html#the-plaintext-protocol) if `-graphiteListenAddr` is set and in [OpenTSDB format](http://opentsdb.net/docs/build/html/api_telnet/put.html) if `-opentsdbListenAddr` is set.
 - VictoriaMetrics supports backfilling, i.e. data points from the past may be inserted into the DB.
 - Time series data may be exported via `/api/v1/export?match=<metric_selector>`. Optional `start` and `end` timestamps may be added for exporting time series in the given time range.
 - Time series may be deleted via `/api/v1/admin/tsdb/delete_series?match[]=<metric_selector>`.
