Use Telegraf to dual write to InfluxDB
InfluxDB 3 Core is in Public Alpha
InfluxDB 3 Core is in public alpha and available for testing and feedback, but is not meant for production use. Both the product and this documentation are works in progress. We welcome and encourage your input about your experience with the alpha and invite you to join our public channels for updates and to share feedback.
Use Telegraf to write your data simultaneously to multiple InfluxDB instances or clusters. This method, known as “dual writing,” is useful for backing up data to a separate instance or for migrating from other versions of InfluxDB to InfluxDB 3 Core.
The following example configures Telegraf for dual writing to InfluxDB 3 Core and an InfluxDB v2 OSS instance.
The InfluxDB v2 output plugin twice–the first pointing to InfluxDB 3 Core and the other to an InfluxDB v2 OSS instance.
Two different tokens–one for InfluxDB v2 OSS and one for Clustered. Configure both tokens as environment variables and use string interpolation in your Telegraf configuration file to reference each environment variable.
While in alpha, InfluxDB 3 Core does not require an authorization token. For the
token
option, provide an arbitrary, non-empty token string.
Sample configuration
# Include any other input, processor, or aggregator plugins that you want to
# include in your configuration.
# Send data to InfluxDB 3 Core
[[outputs.influxdb_v2]]
## The InfluxDB 3 Core URL
urls = ["http://localhost:8181"]
## InfluxDB 3 Core authorization token
token = "${INFLUX_TOKEN}"
## For InfluxDB 3 Core, set organization to an empty string
organization = ""
## Destination database to write into
bucket = "DATABASE_NAME"
# Send data to InfluxDB v2 OSS
[[outputs.influxdb_v2]]
## The InfluxDB v2 OSS URL
urls = ["http://localhost:8086"]
## OSS token for authentication
token = "${INFLUX_TOKEN_OSS}"
## Organization is the name of the organization you want to write to.
organization = "ORG_NAME_OSS"
## Destination bucket to write to
bucket = "BUCKET_NAME_OSS"
Telegraf lets you dual write data to any version of InfluxDB using the
influxdb
(InfluxDB v1)
and influxdb_v2
output plugins.
A single Telegraf agent sends identical data sets to all target outputs.
You cannot filter data based on the output.
InfluxDB v1 does not support the unsigned integer data type. You can only write unsigned integer field values to InfluxDB v2- and 3-based products.
