Dual write to InfluxDB OSS and InfluxDB Clustered
If you want to back up your data in two places, or if you’re migrating from InfluxDB OSS to InfluxDB Clustered, you may want to set up Telegraf to dual write.
Use Telegraf to write to both InfluxDB OSS and InfluxDB Clustered simultaneously.
The sample configuration below uses:
- The InfluxDB v2 output plugin twice: first pointing to the OSS instance and then to the InfluxDB cluster.
- Two different tokens, one for OSS and one for Clustered. You’ll need to configure both tokens as environment variables (see how to Configure authentication credentials as environment variables).
Use the configuration below to write your data to both OSS and Clustered instances simultaneously.
Sample configuration
# 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 = "${INFLUX_TOKEN_OSS}"
## Organization is the name of the organization you want to write to. It must already exist.
organization = "ORG_NAME_OSS"
## Destination bucket to write to.
bucket = "BUCKET_NAME_OSS"
# Send data to InfluxDB cluster
[[outputs.influxdb_v2]]
## The URLs of the InfluxDB instance.
urls = ["https://cluster-host.com"]
## Cloud token for authentication.
token = "${INFLUX_TOKEN}"
## For InfluxDB Clustered, set organization to an empty string.
organization = ""
## Destination bucket to write into.
bucket = "DATABASE_NAME"
