## Fluentbit setup
|
|
|
|
Specify [http output](https://docs.fluentbit.io/manual/pipeline/outputs/http) section in the `fluentbit.conf`
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/VictoriaLogs/):
|
|
|
|
```conf
|
|
[Output]
|
|
Name http
|
|
Match *
|
|
host localhost
|
|
port 9428
|
|
uri /insert/jsonline?_stream_fields=stream&_msg_field=log&_time_field=date
|
|
format json_lines
|
|
json_date_format iso8601
|
|
```
|
|
|
|
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 `uri`.
|
|
|
|
It is recommended verifying whether the initial setup generates the needed [log fields](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#data-model)
|
|
and uses the correct [stream fields](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#stream-fields).
|
|
This can be done by specifying `debug` [parameter](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/#http-parameters) in the `uri`
|
|
and inspecting VictoriaLogs logs then:
|
|
|
|
```conf
|
|
[Output]
|
|
Name http
|
|
Match *
|
|
host localhost
|
|
port 9428
|
|
uri /insert/jsonline?_stream_fields=stream&_msg_field=log&_time_field=date&debug=1
|
|
format json_lines
|
|
json_date_format iso8601
|
|
```
|
|
|
|
If some [log fields](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#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:
|
|
|
|
```conf
|
|
[Output]
|
|
Name http
|
|
Match *
|
|
host localhost
|
|
port 9428
|
|
uri /insert/jsonline?_stream_fields=stream&_msg_field=log&_time_field=date&ignore_fields=log.offset,event.original
|
|
format json_lines
|
|
json_date_format iso8601
|
|
```
|
|
|
|
If the Fluentbit 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:
|
|
|
|
```conf
|
|
[Output]
|
|
Name http
|
|
Match *
|
|
host localhost
|
|
port 9428
|
|
uri /insert/jsonline?_stream_fields=stream&_msg_field=log&_time_field=date
|
|
format json_lines
|
|
json_date_format iso8601
|
|
compress gzip
|
|
```
|
|
|
|
By default, the ingested logs are stored in the `(AccountID=0, ProjectID=0)` [tenant](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#multitenancy).
|
|
If you need storing logs in other tenant, then specify the needed tenant via `header` options.
|
|
For example, the following `fluentbit.conf` config instructs Fluentbit to store the data to `(AccountID=12, ProjectID=34)` tenant:
|
|
|
|
```conf
|
|
[Output]
|
|
Name http
|
|
Match *
|
|
host localhost
|
|
port 9428
|
|
uri /insert/jsonline?_stream_fields=stream&_msg_field=log&_time_field=date
|
|
format json_lines
|
|
json_date_format iso8601
|
|
header AccountID 12
|
|
header ProjectID 23
|
|
```
