# Nodetool cfhistograms (tablehistograms) **cfhistograms** ` `- This command provides statistics about a table, including number of SSTables, read/write latency, partition size and column count. cfhistograms covers all operations since the last time you ran the nodetool cfhistograms command. Note that this command can also be used for `tablehistograms`. This command uses the following syntax: ```shell nodetool cfhistograms keyspaces cfname ``` For example: to get statistics about the `standard1` table in the `keyspaces1` keyspace, use this command: ```shell nodetool cfhistograms keyspaces1 standard1 ``` | Percentile | SSTables value | Write Latency | Read Latency | Partition Size | Cell Count | |--------------|------------------|-----------------|----------------|------------------|--------------| | 50% | 10 | 42 | 20 | 210 | 5 | | 75% | 20 | 42 | 24 | 280 | 5 | | 95% | 25 | 42 | 42 | 300 | 5 | | 98% | 25 | 42 | 770 | 310 | 5 | | 99% | 26 | 42 | 2759 | 310 | 5 | | Min | 0 | 36 | 7 | 210 | 5 | | Max | 26 | 42 | 35425 | 310 | 5 | In this example, 95% of the write latency measurements were 42 microseconds (μs) or less, 95% of the read latencies were 42 μs or less, and 95% of the partitions are 300 bytes or less. The SSTables column means that the 95% of all single-key read requests touched at most 25 SSTables. | Parameter | Description | |----------------|-----------------------------------------| | SSTables | Distribution number of sstable per read | | Write Latency | Distribution of the Write Latency | | Read Latency | Distribution of the Read Latency | | Partition Size | Estimated row size | | Cell Count | Estimated column count | [Nodetool Reference](https://docs.scylladb.com/manual/master/operating-scylla/nodetool.md)
