-DataDog agent sends the [configured tags](https://docs.datadoghq.com/getting_started/tagging/) to
-undocumented endpoint - `/datadog/intake`. This endpoint isn't supported by VictoriaMetrics yet. This prevents from adding the configured tags to DataDog agent data sent into VictoriaMetrics.
-The workaround is to run a sidecar [vmagent](https://docs.victoriametrics.com/vmagent.html) alongside every DataDog agent, which must run with `DD_DD_URL=http://localhost:8429/datadog` environment variable.
-The sidecar `vmagent` must be configured with the needed tags via `-remoteWrite.label` command-line flag and must forward incoming data with the added tags to a centralized VictoriaMetrics:

-The configuration details are the following:
-1. Set the `dd_url` param for each DataDog agent to the corresponding vmagent proxy address: `dd_url: http://<vmagent-addr>:8429/datadog`
-2. Configure ever sidecar `vmagent` with `-remoteWrite.url` command-line flag, so it forwards the received data to a centralized storage: `-remoteWrite.url=http://victoria-metrics:8428/api/v1/write`
-3. [Specify extra tags](https://docs.victoriametrics.com/vmagent.html#adding-labels-to-metrics) you want to add to the data received from DataDog agent via `-remoteWrite.label` command-line flag at `vmagent` sidecars. For example, the following config adds `team="dev"` and `env="prod"` tags to all the received metrics from DataDog agent: `-remoteWrite.label=team=dev,env=prod`
-
-See [these docs](https://docs.victoriametrics.com/vmagent.html#adding-labels-to-metrics) for details on how to add labels to metrics at `vmagent`.
-
 Extra labels may be added to all the written time series by passing `extra_label=name=value` query args.
 For example, `/datadog/api/v1/series?extra_label=foo=bar` would add `{foo="bar"}` label to all the ingested metrics.

 ## How to send data from InfluxDB-compatible agents such as [Telegraf](https://www.influxdata.com/time-series-platform/telegraf/)
 
 Use `http://<victoriametric-addr>:8428` url instead of InfluxDB url in agents' configs.
