The following metrics:

• clustermesh_global_services
• clustermesh_global_service_exports

Are supposed to export the "total number of global service in the cluster mesh", in fact this is not what they are doing as they only represent the number of remote service and service exports which could be different (for instance some global service which only exist in the local cluster).

This is done in the Global caches here which only get info from remote clusters:

• cilium/pkg/clustermesh/common/services.go

  Line 35 in 0a2680c

  metricTotalGlobalServices metric.Gauge

• cilium/pkg/clustermesh/operator/service_exports.go

  Line 32 in 0a2680c

  metricTotalGlobalServiceExports metric.Gauge

It am not sure if we should actually fix that or simply rename the metrics to clustermesh_remote_global_services and clustermesh_global_remote_service_exports (or similar) though 🤔
