 * **When to use**

 * type for cluster dashboards.
 *
 * **Details**
 *
 * Bigint gauge named `effect_cluster_entities`, updated with the entity type as
 * a metric tag.
 *
 * **Gotchas**
 *
 * This gauge is runner-local and sampled by the entity manager loop. Aggregate
 * across runners and expect up to roughly one polling interval of lag.

 * @see {@link shards} for shard ownership on the current runner
