it defaults to the system bundle.
|
||||
|
||||
```yaml tab="File (YAML)"
|
||||
metrics:
|

||||
When using this option, setting the `key` option is required.
|
||||
|
||||

```yaml tab="File (YAML)"
|
||||
metrics:
|
||||

||||
|
||||
##### `insecureSkipVerify`
|
||||
|
||||
_Optional, Default=false_
|
||||
|
||||
If `insecureSkipVerify` is `true`,
|
||||
the TLS connection to the OpenTelemetry Collector accepts any certificate presented by the server regardless of the hostnames it covers.
|
||||
|
||||
```yaml tab="File (YAML)"
|
||||
metrics:
|
||||
openTelemetry:
|

||||
|
||||
```bash tab="CLI"
|
||||
--metrics.openTelemetry.tls.insecureSkipVerify=true
|
||||
```
|
||||
|
||||
#### gRPC configuration
|
||||
|
||||
This instructs the reporter to send metrics to the OpenTelemetry Collector using gRPC.
|
||||
|
||||
```yaml tab="File (YAML)"
|
||||
metrics:
|
||||
openTelemetry:
|
||||
grpc: {}
|
||||
```
|
||||
|
||||
```toml tab="File (TOML)"
|
||||
[metrics]
|
||||
[metrics.openTelemetry.grpc]
|
||||
```
