通过Powershell在MSMQ上的消息数

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

Windows Server 2012/2012 R2 和 Windows 8/8.1 下的 PowerShell 有一堆内置 Cmdlet，可以通过安装Microsoft 消息队列 (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。IE

• 新建-MsmqQueue
• 删除-MsmqQueue
• 发送-MsmqQueue
• 接收-MsmqQueue
• 获取-MsmqQueueManager

有关 MSMQ Cmdlet 帮助的完整列表，请参阅Windows PowerShell 中的 MSMQ Cmdlet，或者Get-Command -Module MSMQ如果您已经安装了该功能。

所以，我看到了这个：我可以用 C# 和 Powershell 做什么？并转到这里：http://jopinblog.wordpress.com/2008/03/12/counting-messages-in-an-msmq-messagequeue-from-c/

并做了这个

# 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');

它奏效了。
