## Constructors

### <a id="Tracon_QuotaUsageQuery__ctor"></a> QuotaUsageQuery\(\)

```csharp
public QuotaUsageQuery()
```

## Properties

### <a id="Tracon_QuotaUsageQuery_AgentName"></a> AgentName

Fetches only this agent's counters. An empty string means tenant-wide.

```csharp
public string? AgentName { get; init; }
```

#### Property Value

 [string](https://learn.microsoft.com/dotnet/api/system.string)?

### <a id="Tracon_QuotaUsageQuery_Period"></a> Period

Fetches only this interval's counters.

```csharp
public QuotaPeriod? Period { get; init; }
```

#### Property Value

 [QuotaPeriod](/api/tracon.quotaperiod/)?

### <a id="Tracon_QuotaUsageQuery_PeriodStarts"></a> PeriodStarts

Fetches only the counters of the periods named here, each for the given
first day (local time). [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) applies no period filter:
every counter of every period is returned — the whole history.

```csharp
public IReadOnlyDictionary<QuotaPeriod, DateOnly>? PeriodStarts { get; init; }
```

#### Property Value

 [IReadOnlyDictionary](https://learn.microsoft.com/dotnet/api/system.collections.generic.ireadonlydictionary\-2)<[QuotaPeriod](/api/tracon.quotaperiod/), [DateOnly](https://learn.microsoft.com/dotnet/api/system.dateonly)\>?

#### Remarks

The caller computes the first days from the configured time zone, exactly
as it does for [IQuotaStore.AddUsageAsync](/api/tracon.iquotastore/#Tracon_IQuotaStore_AddUsageAsync_Tracon_QuotaConsumption_System_Collections_Generic_IReadOnlyDictionary_Tracon_QuotaPeriod_System_DateOnly__System_Threading_CancellationToken_); a store does not
know time zones. A period that is not in the map returns no counters, so
an empty map returns an empty list. The filter applies together with
[QuotaUsageQuery.AgentName](/api/tracon.quotausagequery/#Tracon_QuotaUsageQuery_AgentName) and [QuotaUsageQuery.Period](/api/tracon.quotausagequery/#Tracon_QuotaUsageQuery_Period).

The admission check reads usage before every run. Without this filter
each read returned the tenant's whole history, which only grows.

### <a id="Tracon_QuotaUsageQuery_TenantId"></a> TenantId

The tenant identifier.

```csharp
public required string TenantId { get; init; }
```

#### Property Value

 [string](https://learn.microsoft.com/dotnet/api/system.string)

## Methods

### <a id="Tracon_QuotaUsageQuery_Equals_System_Object_"></a> Equals\(object?\)

```csharp
public override bool Equals(object? obj)
```

#### Returns

 [bool](https://learn.microsoft.com/dotnet/api/system.boolean)

### <a id="Tracon_QuotaUsageQuery_GetHashCode"></a> GetHashCode\(\)

```csharp
public override int GetHashCode()
```

#### Returns

 [int](https://learn.microsoft.com/dotnet/api/system.int32)

### <a id="Tracon_QuotaUsageQuery_ToString"></a> ToString\(\)

```csharp
public override string ToString()
```

#### Returns

 [string](https://learn.microsoft.com/dotnet/api/system.string)

## Operators

### <a id="Tracon_QuotaUsageQuery_op_Equality_Tracon_QuotaUsageQuery_Tracon_QuotaUsageQuery_"></a> operator ==\(QuotaUsageQuery?, QuotaUsageQuery?\)

```

#### Parameters

`left` [QuotaUsageQuery](/api/tracon.quotausagequery/)?

`right` [QuotaUsageQuery](/api/tracon.quotausagequery/)?

#### Returns

 [bool](https://learn.microsoft.com/dotnet/api/system.boolean)

### <a id="Tracon_QuotaUsageQuery_op_Inequality_Tracon_QuotaUsageQuery_Tracon_QuotaUsageQuery_"></a> operator \!=\(QuotaUsageQuery?, QuotaUsageQuery?\)
