Detailed Description

Manages Prometheus metrics for cluster communication and node tracking.

This class tracks cluster-related metrics including:

• Total number of nodes detected in the cluster
• Health status of cluster communication

Constructor & Destructor Documentation

Metrics()

cluster::Metrics::Metrics

(

)

Constructs a Metrics instance and initializes metrics.

Sets the initial node count to 1 (self) and marks communication as healthy.

Member Function Documentation

onNewState()

void cluster::Metrics::onNewState	(	ClioNode::CUuid	uuid,
		std::shared_ptr< Backend::ClusterData const >	clusterData )

Updates metrics based on new cluster state.

This callback is invoked when cluster state changes. It updates:

• Health status based on whether cluster data is available
• Node count to reflect the current cluster size

Parameters

uuid	The UUID of the node (unused in current implementation)
clusterData	Shared pointer to the current cluster data; may be empty if communication failed
