pyroscope.write

BETA: This is a beta component. Beta components are subject to breaking changes, and may be replaced with equivalent functionality that cover the same use case.

pyroscope.write receives performance profiles from other components and forwards them to a series of user-supplied endpoints using Pyroscope’ Push API.

Multiple pyroscope.write components can be specified by giving them different labels.

Usage

river Copy

pyroscope.write "LABEL" {
  endpoint {
    url = PYROSCOPE_URL

    ...
  }

  ...
}

Arguments

The following arguments are supported:

Blocks

The following blocks are supported inside the definition of pyroscope.write:

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

endpoint block

The endpoint block describes a single location to send profiles to. Multiple endpoint blocks can be provided to send profiles to multiple locations.

The following arguments are supported:

At most one of the following can be provided:

• bearer_token argument.
• bearer_token_file argument.
• basic_auth block.
• authorization block.
• oauth2 block.

When multiple endpoint blocks are provided, profiles are concurrently forwarded to all configured locations.

basic_auth block

password and password_file are mutually exclusive, and only one can be provided inside a basic_auth block.

authorization block

credential and credentials_file are mutually exclusive, and only one can be provided inside an authorization block.

oauth2 block

client_secret and client_secret_file are mutually exclusive, and only one can be provided inside an oauth2 block.

The oauth2 block may also contain a separate tls_config sub-block.

tls_config block

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

When configuring client authentication, both the client certificate (using cert_pem or cert_file) and the client key (using key_pem or key_file) must be provided.

When min_version is not provided, the minimum acceptable TLS version is inherited from Go’s default minimum version, TLS 1.2. If min_version is provided, it must be set to one of the following strings:

• "TLS10" (TLS 1.0)
• "TLS11" (TLS 1.1)
• "TLS12" (TLS 1.2)
• "TLS13" (TLS 1.3)

Exported fields

The following fields are exported and can be referenced by other components:

Component health

pyroscope.write is only reported as unhealthy if given an invalid configuration. In those cases, exported fields are kept at their last healthy values.

Debug information

pyroscope.write does not expose any component-specific debug information.

Example

river Copy

pyroscope.write "staging" {
  // Send metrics to a locally running Pyroscope instance.
  endpoint {
    url = "http://pyroscope:4100"
    headers = {
      "X-Scope-OrgID" = "squad-1",
    }
  }
  external_labels = {
    "env" = "staging",
  }
}


pyroscope.scrape "default" {
  targets = [
    {"__address__" = "pyroscope:4100", "service_name"="pyroscope"},
    {"__address__" = "agent:12345", "service_name"="agent"},
  ]
  forward_to = [pyroscope.write.staging.receiver]
}
