* Many collectors don't support forwarding url query params to the remote system. It makes impossible to define stream fields for it. Workaround with proxy between VictoriaLogs and log shipper is too complicated solution.
* This commit adds the following changes:
* Adds fallback to to headers params, if query param is empty for:
_msg_field -> VL-Msg-Field
_stream_fields -> VL-Stream-Fields
_ignore_fields -> VL-Ignore-Fields
_time_field -> VL-Time-Field
* removes deprecations from victorialogs compose files, added more
output format examples for logstash, telegraf, fluent-bit

# Fluentbit setup
|
|
|
|
VictoriaLogs supports given below Fluentbit outputs:
|
|
- [Elasticsearch](#elasticsearch)
|
|
- [Loki](#loki)
|
|
- [HTTP JSON](#http)
|
|
|
|
## Elasticsearch
|
|
|
|
Specify [elasticsearch output](https://docs.fluentbit.io/manual/pipeline/outputs/elasticsearch) section in the `fluentbit.conf`
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/):
|
|
|
|
```conf
|
|
[Output]
|
|
Name es
|
|
Match *
|
|
host victorialogs
|
|
port 9428
|
|
compress gzip
|
|
path /insert/elasticsearch
|
|
header AccountID 0
|
|
header ProjectID 0
|
|
header VL-Stream-Fields path
|
|
header VL-Msg-Field log
|
|
header VL-Time-Field @timestamp
|
|
```
|
|
|
|
## Loki
|
|
|
|
Specify [loki output](https://docs.fluentbit.io/manual/pipeline/outputs/loki) section in the `fluentbit.conf`
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/):
|
|
|
|
```conf
|
|
[OUTPUT]
|
|
name loki
|
|
match *
|
|
host victorialogs
|
|
uri /insert/loki/api/v1/push
|
|
port 9428
|
|
label_keys $path,$log,$time
|
|
header VL-Msg-Field log
|
|
header VL-Time-Field time
|
|
header VL-Stream-Fields path
|
|
```
|
|
|
|
## HTTP
|
|
|
|
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/):
|
|
|
|
```fluentbit
|
|
[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/#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 `uri`
|
|
and inspecting VictoriaLogs logs then:
|
|
|
|
```fluentbit
|
|
[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/#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:
|
|
|
|
```fluentbit
|
|
[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:
|
|
|
|
```fluentbit
|
|
[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/#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:
|
|
|
|
```fluentbit
|
|
[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
|
|
```
|
|
