If you want to back up your data in two places, or if you're migrating from InfluxDB OSS to {{< product-name >}}, you may want to set up Telegraf to dual write.
Use Telegraf to write to both InfluxDB OSS and {{< product-name >}} simultaneously.
The sample configuration below uses:
Use the configuration below to write your data to both OSS and Cloud Serverless instances simultaneously.
# Include any other input, processor, or aggregator plugins that you want to include in your configuration.
# Send data to InfluxDB OSS v2
[[outputs.influxdb_v2]]
## The URLs of the InfluxDB instance.
##
## Multiple URLs can be specified for a single cluster, only ONE of the
## urls will be written to each interval.
## urls exp: http://127.0.0.1:9999
urls = ["http://localhost:8086"]
## OSS token for authentication.
token = "${INFLUX_TOKEN_OSS}"
## Organization is the name of the organization you want to write to. It must already exist.
organization = "ORG_NAME_OSS"
## Destination bucket to write to.
bucket = "BUCKET_NAME_OSS"
# Send data to InfluxDB Cloud Serverless instance
[[outputs.influxdb_v2]]
## The URLs of the InfluxDB Cloud instance.
urls = ["https://{{< influxdb/host >}}"]
## Cloud token for authentication.
token = "${INFLUX_TOKEN}"
## For InfluxDB Cloud Serverless, set organization to an empty string.
organization = ""
## Destination bucket to write into.
bucket = "BUCKET_NAME"
