| Parameter Name                     | Default Value   | Introduced in Version | Last Updated in Version |
| ---------------------------------- | ---------------- | --------------------- | ----------------------- |
| `NodeExporterListenAddress`        | `:9100`         | 0                     | 0                       |

**Description:**

Sets the specific address for publishing metrics.

| `EnableMetricReporting`            | `false`         | 0                     | 0                       |

**Description:**

Determines whether the metrics collection service is enabled for the node. When enabled, the node will collect performance and usage metrics from the specific instance of [`algod`](https://specs.algorand.co/node/non-normative/node-nn-algod). Additionally, machine-wide metrics are also collected. This enables monitoring across all instances on the same machine, helping with performance analysis and troubleshooting.

**Description:**

Specifies the path to the `node_exporter` binary, which exposes node metrics for monitoring and integration with systems like _Prometheus_. The `node_exporter` collects and exposes various performance and health metrics from the node.
