Add dispatch_namespace label to worker invocation metrics#18
Merged
Conversation
Adds dispatchNamespaceName as a dimension in the workersInvocationsAdaptive GraphQL query and exposes it as a dispatch_namespace label on all cloudflare_worker_* metrics. This allows grouping worker metrics by dispatch namespace, which is useful for Workers for Platforms deployments where multiple user workers share a namespace.

What/Why?
Adds
dispatchNamespaceNameas a dimension in theworkersInvocationsAdaptiveGraphQL query and exposes it as adispatch_namespacelabel on allcloudflare_worker_*metrics.For Workers for Platforms deployments, user workers run under a dispatch namespace with UUID-based script names. Without this label, there's no way to group or filter metrics by namespace — only by individual
script_name, which is too granular. Thedispatch_namespacelabel enables aggregating all user workers within a namespace (e.g.sum by (dispatch_namespace)).Non-WfP workers have an empty
dispatch_namespace=""label, which is consistent with how other optional dimensions behave.Rollout/Rollback
