Question

我想提供一个队列路径并获取消息的数量。关于如何做到这一点的任何建议？

Answer 1

这将列出计算机上的所有队列和消息数：

gwmi -class Win32_PerfRawData_MSMQ_MSMQQueue -computerName $computerName |
    ft -prop Name, MessagesInQueue

Answer 2

所以，我看到了这个：What can I do with C# and Powershell?并且来到了这里：http://jopinblog.wordpress.com/2008/03/12/counting-messages-in-an-msmq-messagequeue-from-c/

并且做了这个

# Add the .NET assembly MSMQ to the environment.
[Reflection.Assembly]::LoadWithPartialName("System.Messaging")

# Create a new QueueSizer .NET class help to warp MSMQ calls.
$qsource = @"
public class QueueSizer
    {
        public static System.Messaging.Message PeekWithoutTimeout(System.Messaging.MessageQueue q, System.Messaging.Cursor cursor, System.Messaging.PeekAction action)
        {
            System.Messaging.Message ret = null;
            try
            {
                // Peek at the queue, but timeout in one clock tick.
                ret = q.Peek(new System.TimeSpan(1), cursor, action);
            }
            catch (System.Messaging.MessageQueueException mqe)
            {
                // Trap MSMQ exceptions but only ones relating to timeout. Bubble up any other MSMQ exceptions.
                if (!mqe.Message.ToLower().Contains("timeout"))
                {
                    throw;
                }
            }
            return ret;
        }

        // Main message counting method.
        public static int GetMessageCount(string queuepath)
        {
            // Get a specific MSMQ queue by name.
            System.Messaging.MessageQueue q = new System.Messaging.MessageQueue(queuepath);

            int count = 0;

            // Create a cursor to store the current position in the queue.
            System.Messaging.Cursor cursor = q.CreateCursor();

            // Have quick peak at the queue.
            System.Messaging.Message m = PeekWithoutTimeout(q, cursor, System.Messaging.PeekAction.Current);

            if (m != null)
            {
                count = 1;

                // Keep on iterating through the queue and keep count of the number of messages that are found.
                while ((m = PeekWithoutTimeout(q, cursor, System.Messaging.PeekAction.Next)) != null)
                {
                    count++;
                }
            }

            // Return the tally.
            return count;
        }
    }
"@

# Add the new QueueSizer class helper to the environment.
Add-Type -TypeDefinition $qsource -ReferencedAssemblies C:\Windows\assembly\GAC_MSIL\System.Messaging\2.0.0.0__b03f5f7f11d50a3a\System.Messaging.dll

# Call the helper and get the message count.
[QueueSizer]::GetMessageCount('mymachine\private$\myqueue');

它有效。

Answer 3

Windows Server 2012/2012下的PowerShell R2和Windows 8 / 8.1有一堆内置的Cmdlet，可以通过安装 Microsoft Message Queue（MSMQ）服务器核心功能来使用。

# Get all message queues
Get-MsmqQueue;

# Get all the private message queues.
# Display only the QueueName and MessageCount for each queue.
Get-MsmqQueue -QueueType Private | Format-Table -Property QueueName,MessageCount;

还有许多其他Cmdlet可用于队列管理和消息创建。即。

新-MsmqQueue
移除-MsmqQueue
发送-MsmqQueue
接收-MsmqQueue
获取-MsmqQueueManager

有关MSMQ Cmdlet帮助的完整列表，请参阅MSMQ Cmdlets in Windows PowerShell或Get-Command -Module MSMQ（如果您已安装此功能）。

Answer 4

Irwin提供的解决方案并非如此。

您可以通过.GetAllMessages来完成一次检查，而不是foreach循环。

$QueueName = "MycomputerName\MyQueueName" 
$QueuesFromDotNet =  new-object System.Messaging.MessageQueue $QueueName


If($QueuesFromDotNet.GetAllMessages().Length -gt $Curr)
{
    //Do Something
}

.Length为您提供给定队列中的消息数。

Answer 5

按照this link的处方，您可以使用

$queues = Get-WmiObject Win32_PerfFormattedData_msmq_MSMQQueue
$queues | ft -property Name,MessagesInQueue

获取本地队列的大小，或

$host = ...
$cred = get-credential
$queues = Get-WmiObject Win32_PerfFormattedData_msmq_MSMQQueue -computer $host -credential $cred
$queues | ft -property Name,MessagesInQueue

用于远程队列。

Answer 6

PowerShell Community Extensions中有一组MSMQ管理cmdlet。尝试一下，看看是否有任何帮助（可能是Get-MSMQueue）：

Clear-MSMQueue
Get-MSMQueue
New-MSMQueue
Receive-MSMQueue
Send-MSMQueue
Test-MSMQueue

注意：尝试抓取基于beta 2.0模块的distrubtion - 只需记住在解压缩之前“解锁”zip。

Answer 7

将此用于c＃块以获取计数。它使用性能计数器来查询一次：

public static int GetMessageCount(string machineName, string queuepath)
    {
        var queueCounter = new PerformanceCounter(
            "MSMQ Queue",
            "Messages in Queue",
            string.Format("{0}\\{1}", machineName, queuepath),
            machineName);

        return (int)queueCounter.NextValue();
    }

这比重复查看效率更高，因为工作主要在远程计算机上完成，也比GetAllMessages更有效，因为这会返回额外的消息数据，然后计算元素 - 在任何实际负载下都会出现糟糕的性能。 p>

Answer 8

我一直在寻找有关访问集群中队列的信息。

对于其他尝试在集群队列上使用powershell命令的人：

在群集节点之一上：

$env:computername = "MsmqHostName"
Get-MsmqQueue | Format-Table -Property QueueName,MessageCount

从集群中远程：

Invoke-Command -ScriptBlock {$env:computername = "msmqHostName";Get-MsmqQueue | Format-Table -Property QueueName,MessageCount } -ComputerName ClusternNodeName

Answer 9

尝试其中一个......

function GetMessageCount2($queuename)
{
    $queuename = $env:computername + "\" + $queuename
    return (Get-WmiObject Win32_PerfFormattedData_msmq_MSMQQueue | Where-Object -filterscript {$_.Name -eq $queuename}).MessagesinQueue 
}

function GetMessageCount3($queuename)
{
    return (Get-MsmqQueue | Where-Object -FilterScript {$_.QueueName -eq $queuename}).MessageCount
}

Answer 10

我正在寻找一个很好的答案，虽然Irwin的回答让我在正确的基础上，我正在寻找一些更多的Powershell-ish代码。这样做的主要原因是处理更改，因为在.Net运行时中加载了类型，因此无法多次Add-Type，并且无法在不关闭powershell实例的情况下卸载。

所以我接受了他的回答并提出了：

# Add the .NET assembly MSMQ to the environment.
[Reflection.Assembly]::LoadWithPartialName("System.Messaging") | out-Null

function Get-QueueNames([Parameter(Mandatory=$true)][String]$machineName, [String]$servicePrefix)
{
    [System.Messaging.MessageQueue]::GetPrivateQueuesByMachine($machineName) |
        ForEach-Object { $_.Path } | 
        Where-Object { $_ -like "*$($servicePrefix).*" } 
}

function Get-MessageCount([parameter(Mandatory=$true)][String]$queueName)
{
    function HasMessage
    {
        param
        (
            [System.Messaging.MessageQueue]$queue,
            [System.Messaging.Cursor]$cursor,
            [System.Messaging.PeekAction]$action
        )

        $hasMessage = $false
        try
        {
            $timeout = New-Object System.TimeSpan -ArgumentList 1
            $message = $queue.Peek($timeout, $cursor, $action)
            if ($message -ne $null)
            {
                $hasMessage = $true
            }
        }
        catch [System.Messaging.MessageQueueException]
        {
            # Only trap timeout related exceptions
            if ($_.Exception.Message -notmatch "timeout")
            {
                throw
            }
        }

        $hasMessage
    }

    $count = 0
    $queue = New-Object System.Messaging.MessageQueue -ArgumentList $queueName
    $cursor = $queue.CreateCursor()

    $action = [System.Messaging.PeekAction]::Current
    $hasMessage = HasMessage $queue $cursor $action
    while ($hasMessage)
    {
        $count++
        $action = [System.Messaging.PeekAction]::Next
        $hasMessage = HasMessage $queue $cursor $action
    }

    $count
}

$machineName = "."
$prefix = "something"

Get-QueueNames $machineName $prefix |
    ForEach-Object {
        New-Object PSObject -Property @{
            QueueName = $_
            MessageCount = Get-MessageCount $_
        }
    }

可以优化它，以便第一个函数返回队列而不是队列名称，但我需要两个不同的场景。

Answer 12

这对我有用

[System.Reflection.Assembly]::LoadWithPartialName("System.Messaging") | Out-Null

$AlertCount = 39

$queuePath = ".\private$\test.pdpvts.error"

$queue = New-Object System.Messaging.MessageQueue $queuePath


If($queue.GetAllMessages().Length -gt $AlertCount)
{
    Send-MailMessage -To "Me" -From "Alerts" -Subject "Message queue is full" -Credential mycridentials -UseSsl -SmtpServer mail.google.com
}
