This flag was deprecated since [v1.96.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.96.0). Use `-enableMultitenantHandlers` instead, as it is easier to use and combine with [multitenant URL at vminsert](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#multitenancy-via-labels). See these [docs for details](https://docs.victoriametrics.com/vmagent.html#multitenancy).**

**Update note 2: the `-streamAggr.dropInputLabels` command-line flag at `vmagent` was renamed to `-remoteWrite.streamAggr.dropInputLabels`. `-streamAggr.dropInputLabels` is now used for global streaming aggregation.**

## Routing
|
||||
|
||||
[Single-node VictoriaMetrics](https://docs.victoriametrics.com/single-server-victoriametrics/) supports relabeling,
|
||||
deduplication and stream aggregation for all the received data, scraped or pushed.
|
||||
The processed data is then stored in local storage and **can't be forwarded further**.
|
||||
|
||||
[vmagent](https://docs.victoriametrics.com/vmagent/) supports relabeling, deduplication and stream aggregation for all
|
||||
the received data, scraped or pushed. Then, the collected data will be forwarded to specified `-remoteWrite.url` destinations.
|
||||
The data processing order is the following:
|
||||
1. All the received data is [relabeled](https://docs.victoriametrics.com/vmagent/#relabeling) according to
|
||||
specified `-remoteWrite.relabelConfig`;
|
||||
1. All the received data is [deduplicated](https://docs.victoriametrics.com/stream-aggregation/#deduplication)
|
||||
according to specified `-streamAggr.dedupInterval`;
|
||||
1. All the received data is aggregated according to specified `-streamAggr.config`;
|
||||
1. The resulting data from p1 and p2 is then replicated to each `-remoteWrite.url`;
|
||||
1. Data sent to each `-remoteWrite.url` can be additionally relabeled according to the
|
||||
corresponding `-remoteWrite.urlRelabelConfig` (set individually per URL);
|
||||
1. Data sent to each `-remoteWrite.url` can be additionally deduplicated according to the
|
||||
corresponding `-remoteWrite.streamAggr.dedupInterval` (set individually per URL);
|
||||
1. Data sent to each `-remoteWrite.url` can be additionally aggregated according to the
|
||||
corresponding `-remoteWrite.streamAggr.config` (set individually per URL). Please note, it is not recommended
|
||||
to use `-streamAggr.config` and `-remoteWrite.streamAggr.config` together, unless you understand the complications.
|
||||
|
||||
Typical scenarios for data routing with vmagent:
|
||||
1. **Aggregate incoming data and replicate to N destinations**. For this one should configure `-streamAggr.config`
|
||||
to aggregate the incoming data before replicating it to all the configured `-remoteWrite.url` destinations.
|
||||
2. **Individually aggregate incoming data for each destination**. For this on should configure `-remoteWrite.streamAggr.config`
|
||||
for each `-remoteWrite.url` destination. [Relabeling](https://docs.victoriametrics.com/vmagent/#relabeling)
|
||||
via `-remoteWrite.urlRelabelConfig` can be used for routing only selected metrics to each `-remoteWrite.url` destination.
|
||||
|
||||
## Deduplication
|
||||
|
||||
[vmagent](https://docs.victoriametrics.com/vmagent/) supports online [de-duplication](https://docs.victoriametrics.com/#deduplication) of samples
|
||||
before sending them to the configured `-remoteWrite.url`. The de-duplication can be enabled via the following options:
|
||||
|
||||
- By specifying the desired de-duplication interval via `-remoteWrite.streamAggr.dedupInterval` command-line flag for the particular `-remoteWrite.url`.
|
||||
- By specifying the desired de-duplication interval via `-streamAggr.dedupInterval` command-line flag for all received data
|
||||
or via `-remoteWrite.streamAggr.dedupInterval` command-line flag for the particular `-remoteWrite.url` destination.
|
||||
For example, `./vmagent -remoteWrite.url=http://remote-storage/api/v1/write -remoteWrite.streamAggr.dedupInterval=30s` instructs `vmagent` to leave
|
||||
only the last sample per each seen [time series](https://docs.victoriametrics.com/keyconcepts/#time-series) per every 30 seconds.
|
||||
The de-duplication is performed after applying `-remoteWrite.relabelConfig` and `-remoteWrite.urlRelabelConfig` [relabeling](https://docs.victoriametrics.com/vmagent/#relabeling).
|
||||
The de-deduplication is performed after applying [relabeling](https://docs.victoriametrics.com/vmagent/#relabeling) and
|
||||
before performing the aggregation.
|
||||
If the `-remoteWrite.streamAggr.config` and / or `-streamAggr.config` is set, then the de-duplication is performed individually per each
|
||||
[stream aggregation config](#stream-aggregation-config) for the matching samples after applying [input_relabel_configs](#relabeling).
|
||||
|
||||
If the `-remoteWrite.streamAggr.config` is set, then the de-duplication is performed individually per each [stream aggregation config](#stream-aggregation-config)
|
||||
for the matching samples after applying [input_relabel_configs](#relabeling).
|
||||
|
||||
- By specifying `dedup_interval` option individually per each [stream aggregation config](#stream-aggregation-config) at `-remoteWrite.streamAggr.config`.
|
