VictoriaLogs supports given below Fluentd outputs:
- [Loki](#loki)
- [HTTP JSON](#http)
## Loki
Specify [loki output](https://docs.fluentd.io/manual/pipeline/outputs/loki) section in the `fluentd.conf`
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/):
```conf
<match **>
@type loki
url "http://localhost:9428/insert"
<buffer>
flush_interval 10s
flush_at_shutdown true
</buffer>
custom_headers {"VL-Msg-Field": "log", "VL-Time-Field": "time", "VL-Stream-Fields": "path"}
buffer_chunk_limit 1m
</match>
```
## HTTP
Specify [http output](https://docs.fluentd.io/manual/pipeline/outputs/http) section in the `fluentd.conf`
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/):
```fluentd
<match **>
@type http
endpoint "http://localhost:9428/insert/jsonline"
headers {"VL-Msg-Field": "log", "VL-Time-Field": "time", "VL-Stream-Fields": "path"}
</match>
```
Substitute the host (`localhost`) and port (`9428`) with the real TCP address of VictoriaLogs.
See [these docs](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-parameters) for details on the query args specified in the `endpoint`.
It is recommended verifying whether the initial setup generates the needed [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model)
and uses the correct [stream fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields).
This can be done by specifying `debug` [parameter](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-parameters) in the `endpoint`
and inspecting VictoriaLogs logs then:
```fluentd
<match **>
@type http
endpoint "http://localhost:9428/insert/jsonline&debug=1"
headers {"VL-Msg-Field": "log", "VL-Time-Field": "time", "VL-Stream-Fields": "path"}
</match>
```
If some [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) must be skipped
during data ingestion, then they can be put into `ignore_fields` [parameter](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-parameters).
For example, the following config instructs VictoriaLogs to ignore `log.offset` and `event.original` fields in the ingested logs:
```fluentd
<match **>
@type http
endpoint "http://localhost:9428/insert/jsonline&ignore_fields=log.offset,event.original"
headers {"VL-Msg-Field": "log", "VL-Time-Field": "time", "VL-Stream-Fields": "path"}
</match>
```
If the Fluentd sends logs to VictoriaLogs in another datacenter, then it may be useful enabling data compression via `compress gzip` option.
This usually allows saving network bandwidth and costs by up to 5 times:
```fluentd
<match **>
@type http
endpoint "http://localhost:9428/insert/jsonline&ignore_fields=log.offset,event.original"
headers {"VL-Msg-Field": "log", "VL-Time-Field": "time", "VL-Stream-Fields": "path"}
compress gzip
</match>
```
By default, the ingested logs are stored in the `(AccountID=0, ProjectID=0)` [tenant](https://docs.victoriametrics.com/victorialogs/keyconcepts/#multitenancy).
If you need storing logs in other tenant, then specify the needed tenant via `header` options.
For example, the following `fluentd.conf` config instructs Fluentd to store the data to `(AccountID=12, ProjectID=34)` tenant:
```fluentd
<match **>
@type http
endpoint "http://localhost:9428/insert/jsonline"
headers {"VL-Msg-Field": "log", "VL-Time-Field": "time", "VL-Stream-Fields": "path"}
header AccountID 12
header ProjectID 23
</match>
```
