### hh_node (Enterprise only)
Available in InfluxDB Enterprise 1.9.8 and later.
The `hh_node` measurement stores hinted handoff statistics for all queues (shards) for a given node.
The `hh_node` measurement has one additional tag:
- `node` - The destination node for the recorded metrics.
#### queueTotalSize
Total bytes of disk space used by all hinted handoff queues for a single node.
Tracks the disk usage of all hinted handoff queues for a given node (not the bytes waiting to be processed). Due to the implementation of the hinted handoff queue,
a lag occurs between when bytes are processed and when they're removed from the disk.
`queueTotalSize` is used to determine when a node's hinted handoff queue has reached the
maximum size configured in the [hinted-handoff max-size](https://docs.influxdata.com/enterprise_influxdb/v1.9/administration/configure/config-data-nodes/#max-size) parameter.
---
### hh_processor (Enterprise only)
The `hh_processor` measurement stores statistics for a single queue (shard).
In InfluxDB Enterprise, there is a hinted handoff processor on each data node.
