prometheus.exporter.memcached

The prometheus.exporter.memcached component embeds memcached_exporter for collecting metrics from a Memcached server.

Usage

river 
prometheus.exporter.memcached "LABEL" {
}

Arguments

The following arguments are supported:

NameTypeDescriptionDefaultRequired
addressstringThe Memcached server address."localhost:11211"no
timeoutdurationThe timeout for connecting to the Memcached server."1s"no

Blocks

The prometheus.exporter.memcached component does not support any blocks, and is configured fully through arguments.

Exported fields

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

NameTypeDescription
targetslist(map(string))The targets that can be used to collect exporter metrics.

For example, the targets can either be passed to a discovery.relabel component to rewrite the targets’ label sets, or to a prometheus.scrape component that collects the exposed metrics.

The exported targets will use the configured in-memory traffic address specified by the run command.

Component health

prometheus.exporter.memcached is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

prometheus.exporter.memcached does not expose any component-specific debug information.

Debug metrics

prometheus.exporter.memcached does not expose any component-specific debug metrics.

Examples

This minimal example uses a prometheus.exporter.memcached component to collect metrics from a Memcached server running locally, and scrapes the metrics using a prometheus.scrape component:

river 
prometheus.exporter.memcached "example" {
    address = "localhost:13321"
    timeout = "5s"
}

prometheus.scrape "example" {
    targets    = [prometheus.exporter.memcached.example.targets]
    forward_to = [prometheus.remote_write.default.receiver]
}

prometheus.remote_write "default" {
  endpoint {
    url = "prometheus.example.com/api/v1/write"

    basic_auth {
      username = "user"
      password = "pass"
    }
  }
}
