# Metrics By default Prometheus metrics are enabled for all clients. The metrics are exposed to the Docker network and accessible only from other containers - refer to [Exposing ports](/slingnode.ethereum/architecture/exposing-ports.md) page for details on exposing them to the host or to the network. The metrics can be disabled by overriding the following variables and setting them to false: ```yaml execution_client_metrics_enabled: true consensus_client_metrics_enabled: true validator_client_metrics_enabled: true ``` The ports the metrics are exposed on can be modified using the following variables: ```yaml execution_client_metrics_port: 6060 consensus_client_metrics_port: 8008 validator_client_metrics_port: 8009 ``` ### Geth expensive metrics Be default Geth's expensive metrics are enabled. They can be disabled by overriding the following variable and setting it to false: ```yaml geth_metrics_expensive_enabled: true ``` ## slingnode.ethereum\_observability SlingNode has developed an [Ansible role that can deploy an Observability stack](https://slingnode.gitbook.io/slingnode.ethereum_observability/) that seamlessly integrates with nodes deployed using slingnode.ethereum role. The role deploys Prometheus that will automatically start scraping the metrics. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
