VictoriaLogs supports both client open-telemetry [SDK](https://opentelemetry.io/docs/languages/) and [collector](https://opentelemetry.io/docs/collector/).
|
|
|
|
## Client SDK
|
|
|
|
Specify `EndpointURL` for http-exporter builder.
|
|
|
|
Consider the following example for `golang` `SDK`:
|
|
|
|
```go
|
|
// Create the OTLP log exporter that sends logs to configured destination
|
|
logExporter, err := otlploghttp.New(ctx,
|
|
otlploghttp.WithEndpointURL("http://victorialogs:9428/insert/opentelemetry/v1/logs"),
|
|
)
|
|
```
|
|
|
|
Optionally, [stream fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) could be defined via headers:
|
|
|
|
```go
|
|
// Create the OTLP log exporter that sends logs to configured destination
|
|
logExporter, err := otlploghttp.New(ctx,
|
|
otlploghttp.WithEndpointURL("http://victorialogs:9428/insert/opentelemetry/v1/logs"),
|
|
otlploghttp.WithHeaders(map[string]string{"VL-Stream-Fields": "telemetry.sdk.language,severity"}),
|
|
)
|
|
|
|
```
|
|
|
|
Given config defines 2 stream fields - `severity` and `telemetry.sdk.language`.
|
|
|
|
See also [HTTP headers](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-headers)
|
|
|
|
## Collector configuration
|
|
|
|
VictoriaLogs supports given below OpenTelemetry collector exporters:
|
|
|
|
* [Elasticsearch](#elasticsearch)
|
|
* [Loki](#loki)
|
|
* [OpenTelemetry](#opentelemetry)
|
|
|
|
### Elasticsearch
|
|
|
|
```yaml
|
|
exporters:
|
|
elasticsearch:
|
|
endpoints:
|
|
- http://victorialogs:9428/insert/elasticsearch
|
|
headers:
|
|
VL-Msg-Field: "Body" # Optional.
|
|
receivers:
|
|
filelog:
|
|
include: [/tmp/logs/*.log]
|
|
resource:
|
|
region: us-east-1
|
|
service:
|
|
pipelines:
|
|
logs:
|
|
receivers: [filelog]
|
|
exporters: [elasticsearch]
|
|
```
|
|
|
|
Please note that every ingested log entry **must** contain at least a `_msg` field with the actual log message. By default,
|
|
the Elasticsearch exporter may place the log message in the `Body` field. In this case, you can specify the field mapping via:
|
|
```yaml
|
|
headers:
|
|
VL-Msg-Field: "Body"
|
|
```
|
|
|
|
VictoriaLogs also support specify `AccountID`, `ProjectID`, log timestamp and other fields via [HTTP headers](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-headers).
|
|
|
|
### Loki
|
|
|
|
```yaml
|
|
exporters:
|
|
loki:
|
|
endpoint: http://victorialogs:9428/insert/loki/api/v1/push
|
|
receivers:
|
|
filelog:
|
|
include: [/tmp/logs/*.log]
|
|
resource:
|
|
region: us-east-1
|
|
service:
|
|
pipelines:
|
|
logs:
|
|
receivers: [filelog]
|
|
exporters: [loki]
|
|
```
|
|
|
|
### OpenTelemetry
|
|
|
|
Specify logs endpoint for [OTLP/HTTP exporter](https://github.com/open-telemetry/opentelemetry-collector/blob/main/exporter/otlphttpexporter/README.md) in configuration file
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/VictoriaLogs/):
|
|
|
|
```yaml
|
|
exporters:
|
|
otlphttp:
|
|
logs_endpoint: http://localhost:9428/insert/opentelemetry/v1/logs
|
|
```
|
|
|
|
Optionally, [stream fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) could be defined via headers:
|
|
|
|
```yaml
|
|
exporters:
|
|
otlphttp:
|
|
logs_endpoint: http://localhost:9428/insert/opentelemetry/v1/logs
|
|
headers:
|
|
VL-Stream-Fields: telemetry.sdk.language,severity
|
|
```
|
|
|
|
See also [HTTP headers](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-headers)
|
|
|
|
Substitute `localhost:9428` address inside `exporters.otlphttp.logs_endpoint` with the real address of VictoriaLogs.
|
|
|
|
The ingested log entries can be queried according to [these docs](https://docs.victoriametrics.com/VictoriaLogs/querying/).
