Here are descriptions about values. See Usage for real values:

Key | Description | Example
--- | --- | ---
`alloc_count` | The number of allocated memory blocks that aren’t freed. If this value is continuously increased, there may be a memory leak. | `1400`
`cache_hit_rate` | Percentage of cache used responses in the Groonga process. If there are 10 requests and 7 responses are created from cache, `cache_hit_rate` is `70.0`. The percentage is computed from only requests that use commands that support cache. Here are commands that support cache: select logical_select logical_range_filter logical_count | `29.4`
`command_version` | The Command version that is used by the context. | `1`
`default_command_version` | The default Command version of the Groonga process. | `1`
`max_command_version` | The max Command version of the Groonga process. | `2`
`n_queries` | The number of requests processed by the Groonga process. It counts only requests that use commands that support cache. Here are commands that support cache: select logical_select logical_range_filter logical_count | `29`
`start_time` | New in version 5.0.8. The time that the Groonga process started in UNIX time. | `1441761403`
`starttime` | Deprecated since version 5.0.8: Use `start_time` instead. | `1441761403`
`uptime` | The elapsed time since the Groonga process started in second. For example, `216639` means that `2.5` (= `216639 / 60 / 60 / 24 = 2.507`) days. | `216639`
`version` | The version of the Groonga process. | `5.0.7`
