# Logstash setup
|
|
|
|
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/):
|
|
|
|
```conf
|
|
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.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)
|
|
and inspecting VictoriaLogs logs then:
|
|
|
|
```conf
|
|
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.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 {
|
|
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:
|
|
|
|
```conf
|
|
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:
|
|
|
|
```conf
|
|
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"
|
|
}
|
|
}
|
|
}
|
|
```
