The exported metrics cover:

- DynamoDB-compatible API request rate, success/error split, latency, request/response size, and per-table read/write item counts
- Raft local state, leader identity, current members, commit/applied index, and leader contact lag
- DynamoDB-compatible API request rate, success/system-error/user-error split, latency, in-flight requests, and per-table read/write activity
- Raft local state, leader identity, membership, last-log/commit/applied/snapshot index, FSM backlog, and leader contact lag

Provisioned monitoring assets live under:

- `monitoring/prometheus/prometheus.yml`
- `monitoring/grafana/dashboards/elastickv-cluster-overview.json`
- `monitoring/grafana/dashboards/elastickv-cluster-summary.json`
- `monitoring/grafana/dashboards/elastickv-raft-status.json`
- `monitoring/grafana/provisioning/`
- `monitoring/docker-compose.yml`

The provisioned dashboards are organized by operator task:

- `Elastickv Cluster Overview` is the landing page for leader identity, cluster-wide latency/error posture, and per-node Raft health
- `Elastickv Request Health` is the DynamoDB/API drilldown for slow operations, noisy nodes, and hot/erroring tables

For consistency and clarity, consider renaming the dashboard file elastickv-cluster-summary.json to elastickv-request-health.json. This would align the filename with its new title Elastickv Request Health and the description provided in this README. You would also need to update this file to reflect the new name.

- `Elastickv Raft Status` is the control-plane drilldown for membership, node state, index drift, backlog, and leader contact

If you bind `--metricsAddress` to a non-loopback address, `--metricsToken` is required. Prometheus must send the same bearer token, for example:
