| `consul.raft.apply` | Counts the number of Raft transactions applied during the interval. This metric is only reported on the leader. | raft transactions / interval | counter |
| `consul.raft.commitTime` | Measures the time it takes to commit a new entry to the Raft log on the leader. | ms | timer |
**Why they're important:** Taken together, these metrics indicate how long it takes to complete write operations in various parts of the Consul cluster. Generally these should all be fairly consistent and no more than a few milliseconds. Sudden changes in any of the timing values could be due to unexpected load on the Consul servers, or due to problems on the servers themselves.
