Documentation Grafana Cloud Instrument and send data Grafana Alloy Reference Components prometheus prometheus.exporter.mongodb

prometheus.exporter.mongodb

The prometheus.exporter.mongodb component embeds the Percona mongodb_exporter.

We strongly recommend configuring a separate user for Alloy, giving it only the strictly mandatory security privileges necessary for monitoring your node. Refer to the Percona documentation for more information.

Usage

alloy Copy

prometheus.exporter.mongodb "<LABEL>" {
    mongodb_uri = "<MONGODB_URI>"
}

Arguments

You can use the following arguments with prometheus.exporter.mongodb:

MongoDB node connection URI must be in the Standard Connection String Format

Blocks

The prometheus.exporter.mongodb component doesn’t support any blocks. You can configure this component with arguments.

Exported fields

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

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 use the configured in-memory traffic address specified by the run command.

Component health

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

Debug information

prometheus.exporter.mongodb doesn’t expose any component-specific debug information.

Debug metrics

prometheus.exporter.mongodb doesn’t expose any component-specific debug metrics.

Example

The following example uses a prometheus.scrape component to collect metrics from prometheus.exporter.mongodb:

alloy Copy

prometheus.exporter.mongodb "example" {
  mongodb_uri = "mongodb://127.0.0.1:27017"
}

// Configure a prometheus.scrape component to collect MongoDB metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.mongodb.example.targets
  forward_to = [ prometheus.remote_write.default.receiver ]
}

prometheus.remote_write "default" {
  endpoint {
    url = "<PROMETHEUS_REMOTE_WRITE_URL>"
  }
}

Replace the following:

• <PROMETHEUS_REMOTE_WRITE_URL>: The URL of the Prometheus remote_write compatible server to send metrics to.
