Metrics for Grafana to monitor XDCR

Before, I just made an alert on changes_left log entry, but I would like to add graphs to monitor XDCR and alert if there are any isuses. After googling a lot, I found these metrics, but I’m not able to enable/restrive data from them. How would I use these metrics?

couchbase.by_bucket.ep_dcp_xdcr_backoff
(gauge) Number of backoffs for xdcr DCP connections
couchbase.by_bucket.ep_dcp_xdcr_count
(gauge) Number of xdcr DCP connections
shown as connection
couchbase.by_bucket.ep_dcp_xdcr_items_remaining
(gauge) Number of xdcr items remaining to be sent
shown as item
couchbase.by_bucket.ep_dcp_xdcr_items_sent
(gauge) Number of xdcr items sent
shown as item
couchbase.by_bucket.ep_dcp_xdcr_producer_count
(gauge) Number of xdcr producers
couchbase.by_bucket.ep_dcp_xdcr_total_bytes
(gauge)

Thank you for the help
