InfluxDB OSS v1

OpenTSDB

This page documents an earlier version of InfluxDB OSS. InfluxDB 3 Core is the latest stable version.

InfluxDB supports the OpenTSDB “telnet” protocol. When OpenTSDB support is enabled, InfluxDB can act as a drop-in replacement for your OpenTSDB system.

An example input point, and how it is processed, is shown below.

put sys.cpu.user 1356998400 42.5 host=webserver01 cpu=0

When InfluxDB receives this data, a point is written to the database. The point’s Measurement is sys.cpu.user, the timestamp is 1356998400, and the value is 42.5. The point is also tagged with host=webserver01 and cpu=0. Tags allow fast and efficient queries to be performed on your data.

To learn more about enabling OpenTSDB support, check the example configuration file.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On February 3, 2026, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
