package metrics

import "github.com/open-policy-agent/opa/metrics"

Deprecated: This package is intended for older projects transitioning from OPA v0.x and will remain for the lifetime of OPA v1.x, but its use is not recommended. For newer features and behaviours, such as defaulting to the Rego v1 syntax, use the corresponding components in the github.com/open-policy-agent/opa/v1 package instead. See https://www.openpolicyagent.org/docs/latest/v0-compatibility/ for more information.

Package metrics contains helpers for performance metric management inside the policy engine.
