# EffectiveCeiling

!!! info
    This page was generated by extracting information from a JSON Schema
    data file for the API.  It may be missing some information, or otherwise
    suggest approximate or placeholder values based on information in the
    schema file; this is due to limitations on how that data is extracted
    from the underlying Rust code and into the JSON Schema, and then again
    from there and into these docs.

Steady-state ceiling for a single throughput axis, with a tag
for which configuration term produced it.

{{since('dev')}}

This is an object value, with the following properties:


  * `display` - required `string`. Pre-formatted human display preserving the operator's
    original configuration units. A rate configured as
    `10000/hr` renders here as `10000/h` rather than `2.78/s`.
    For concurrency, the integer count. For the synthetic
    reconnect-cycling ceiling, the formula
    `max_deliveries_per_connection × <connection_rate>`.

  * `source` - required [CeilingSource](CeilingSource.md). Which configuration term produced an `EffectiveCeiling`.
    
    {{since('dev')}}

  * `value` - required `number` (`double`). Canonical value. For rate axes: events per second; useful
    for numeric comparison. For concurrency: a count.

### Examples
```json
{
  "display": "string",
  "source": {
    "kind": "primary"
  },
  "value": 4.2
}
```
