* 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

VictoriaLogs supports given below Logstash outputs:
|
|
- [Elasticsearch](#elasticsearch)
|
|
- [Loki](#loki)
|
|
- [HTTP JSON](#http)
|
|
|
|
## Elasticsearch
|
|
|
|
Specify [`output.elasticsearch`](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html) section in the `logstash.conf` file
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/):
|
|
|
|
```logstash
|
|
output {
|
|
elasticsearch {
|
|
hosts => ["http://localhost:9428/insert/elasticsearch/"]
|
|
parameters => {
|
|
"_msg_field" => "message"
|
|
"_time_field" => "@timestamp"
|
|
"_stream_fields" => "host.name,process.name"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Substitute `localhost:9428` address inside `hosts` with the real TCP address of VictoriaLogs.
|
|
|
|
See [these docs](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-parameters) for details on the `parameters` section.
|
|
|
|
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)
|
|
and inspecting VictoriaLogs logs then:
|
|
|
|
```logstash
|
|
output {
|
|
elasticsearch {
|
|
hosts => ["http://localhost:9428/insert/elasticsearch/"]
|
|
parameters => {
|
|
"_msg_field" => "message"
|
|
"_time_field" => "@timestamp"
|
|
"_stream_fields" => "host.name,process.name"
|
|
"debug" => "1"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
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:
|
|
|
|
```logstash
|
|
output {
|
|
elasticsearch {
|
|
hosts => ["http://localhost:9428/insert/elasticsearch/"]
|
|
parameters => {
|
|
"_msg_field" => "message"
|
|
"_time_field" => "@timestamp"
|
|
"_stream_fields" => "host.hostname,process.name"
|
|
"ignore_fields" => "log.offset,event.original"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
If the Logstash sends logs to VictoriaLogs in another datacenter, then it may be useful enabling data compression via `http_compression: true` option.
|
|
This usually allows saving network bandwidth and costs by up to 5 times:
|
|
|
|
```logstash
|
|
output {
|
|
elasticsearch {
|
|
hosts => ["http://localhost:9428/insert/elasticsearch/"]
|
|
parameters => {
|
|
"_msg_field" => "message"
|
|
"_time_field" => "@timestamp"
|
|
"_stream_fields" => "host.hostname,process.name"
|
|
}
|
|
http_compression => true
|
|
}
|
|
}
|
|
```
|
|
|
|
By default, the ingested logs are stored in the `(AccountID=0, ProjectID=0)` [tenant](https://docs.victoriametrics.com/victorialogs/#multitenancy).
|
|
If you need storing logs in other tenant, then specify the needed tenant via `custom_headers` at `output.elasticsearch` section.
|
|
For example, the following `logstash.conf` config instructs Logstash to store the data to `(AccountID=12, ProjectID=34)` tenant:
|
|
|
|
```logstash
|
|
output {
|
|
elasticsearch {
|
|
hosts => ["http://localhost:9428/insert/elasticsearch/"]
|
|
custom_headers => {
|
|
"AccountID" => "1"
|
|
"ProjectID" => "2"
|
|
}
|
|
parameters => {
|
|
"_msg_field" => "message"
|
|
"_time_field" => "@timestamp"
|
|
"_stream_fields" => "host.hostname,process.name"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
## Loki
|
|
|
|
Specify [`output.loki`](https://grafana.com/docs/loki/latest/send-data/logstash/) section in the `logstash.conf` file
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/):
|
|
|
|
```conf
|
|
output {
|
|
loki {
|
|
url => "http://victorialogs:9428/insert/loki/api/v1/push?_stream_fields=host.ip,process.name&_msg_field=message&_time_field=@timestamp"
|
|
}
|
|
}
|
|
```
|
|
|
|
## HTTP
|
|
|
|
Specify [`output.http`](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-http.html) section in the `logstash.conf` file
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/):
|
|
|
|
```conf
|
|
output {
|
|
url => "http://victorialogs:9428/insert/jsonline?_stream_fields=host.ip,process.name&_msg_field=message&_time_field=@timestamp"
|
|
format => "json"
|
|
http_method => "post"
|
|
}
|
|
```
