Documentation Grafana Alloy Reference Components otelcol otelcol.receiver.solace

otelcol.receiver.solace

otelcol.receiver.solace accepts traces from a Solace PubSub+ Event Broker and forwards it to other otelcol.* components.

You can specify multiple otelcol.receiver.solace components by giving them different labels.

Usage

alloy Copy

otelcol.receiver.solace "<LABEL>" {
  queue = "<QUEUE>"
  auth {
    // sasl_plain or sasl_xauth2 or sasl_external block
  }
  output {
    traces  = [...]
  }
}

Arguments

You can use the following arguments with otelcol.receiver.solace:

queue must have the format queue://#telemetry-myTelemetryProfile.

Blocks

You can use the following blocks with otelcol.receiver.solace:

The > symbol indicates deeper levels of nesting. For example, authentication > tls refers to a tls block defined inside an authentication block.

One SASL authentication block is required in the authentication block.

sasl_external must be used together with the tls block.

output

Required

The output block configures a set of components to forward resulting telemetry data to.

The following arguments are supported:

You must specify the output block, but all its arguments are optional. By default, telemetry data is dropped. Configure the metrics, logs, and traces arguments accordingly to send telemetry data to other components.

authentication

The authentication block configures how to authenticate for connecting to the Solace broker. It doesn’t support any arguments and is configured fully through inner blocks.

sasl_external

The sasl_xauth2 block configures how to authenticate to the Solace broker with SASL External. It doesn’t support any arguments or blocks. It must be used with the tls block.

sasl_plain

The sasl_plain block configures how to authenticate to the Solace broker with SASL PLAIN.

The following arguments are supported:

sasl_xauth2

The sasl_xauth2 block configures how to authenticate to the Solace broker with SASL XOauth2.

The following arguments are supported:

debug_metrics

The debug_metrics block configures the metrics that this component generates to monitor its state.

The following arguments are supported:

disable_high_cardinality_metrics is the Alloy equivalent to the telemetry.disableHighCardinalityMetrics feature gate in the OpenTelemetry Collector. It removes attributes that could cause high cardinality metrics. For example, attributes with IP addresses and port numbers in metrics about HTTP and gRPC connections are removed.

flow

The flow block configures the behaviour to use when temporary errors are encountered from the next component. It doesn’t support any arguments and is configured fully through inner blocks.

delayed_retry

The delayed_retry block sets the flow control strategy to delayed retry which will wait before trying to push the message to the next component again.

The following arguments are supported:

tls

The following arguments are supported:

If the server doesn’t support TLS, you must set the insecure argument to true.

To disable tls for connections to the server, set the insecure argument to true.

If you set reload_interval to "0s", the certificate never reloaded.

The following pairs of arguments are mutually exclusive and can’t both be set simultaneously:

• ca_pem and ca_file
• cert_pem and cert_file
• key_pem and key_file

If cipher_suites is left blank, a safe default list is used. Refer to the Go TLS documentation for a list of supported cipher suites.

The curve_preferences argument determines the set of elliptic curves to prefer during a handshake in preference order. If not provided, a default list is used. The set of elliptic curves available are X25519, P521, P256, and P384.

Exported fields

otelcol.receiver.solace doesn’t export any fields.

Component health

otelcol.receiver.solace is only reported as unhealthy if given an invalid configuration.

Debug information

otelcol.receiver.solace doesn’t expose any component-specific debug information.

Example

This example forwards read telemetry data through a batch processor before finally sending it to an OTLP-capable endpoint:

alloy Copy

otelcol.receiver.solace "default" {
  queue = "queue://#telemetry-testprofile"
  broker = "localhost:5672"
  auth {
    sasl_plain {
      username = "alloy"
      password = "password"
    }
  }
  tls {
    insecure             = true
    insecure_skip_verify = true
  }
  output {
    traces = [otelcol.processor.batch.default.input]
  }
}

otelcol.processor.batch "default" {
  output {
    traces  = [otelcol.exporter.otlp.default.input]
  }
}

otelcol.exporter.otlp "default" {
  client {
    endpoint = sys.env("<OTLP_ENDPOINT>")
  }
}
