significantly since the last restore happened so last restore times might not
reflect what would happen if an agent restarts now.
### License Expiration <EnterpriseAlert inline />
| Metric Name | Description | Unit | Type |
| :-------------------------------- | :--------------------------------------------------------------- | :---- | :---- |
| `consul.system.licenseExpiration` | Number of hours until the Consul Enterprise license will expire. | hours | gauge |
**Why they're important:**
This measurement indicates how many hours are left before the Consul Enterprise license expires. When the license expires some
Consul Enterprise features will cease to work. An example of this is that after expiration, it is no longer possible to create
or modify resources in non-default namespaces or to manage namespace definitions themselves even though reads of namespaced
resources will still work.
**What to look for:**
This metric should be monitored to ensure that the license doesn't expire to prevent degradation of functionality.

| `consul.acl.blocked.{check,service}.deregistration` | Increments whenever a deregistration fails for an entity (check or service) is blocked by an ACL. | requests | counter |
| `consul.acl.blocked.{check,node,service}.registration` | Increments whenever a registration fails for an entity (check, node or service) is blocked by an ACL. | requests | counter |
| `consul.acl.blocked.{check,service}.deregistration` | Increments whenever a deregistration fails for an entity (check or service) is blocked by an ACL. | requests | counter |
| `consul.acl.blocked.{check,node,service}.registration` | Increments whenever a registration fails for an entity (check, node or service) is blocked by an ACL. | requests | counter |
| `consul.api.http` | Migrated from consul.http.. this samples how long it takes to service the given HTTP request for the given verb and path. Includes labels for `path` and `method`. `path` does not include details like service or key names, for these an underscore will be present as a placeholder (eg. path=`v1.kv._`) | ms | timer |
| `consul.client.rpc` | Increments whenever a Consul agent in client mode makes an RPC request to a Consul server. This gives a measure of how much a given agent is loading the Consul servers. Currently, this is only generated by agents in client mode, not Consul servers. | requests | counter |
