RabbitMQ–How to remove unacked messages–Part II

Yesterday I showed how to remove unacked messages from a RabbitMQ queue through the Management Portal. Today let us leave the Graphical User Interface behind and solve the same problem from the command line.

Through the command line

RabbitMQ has multiple command line tools available in the sbin folder. The one we need is rabbitmqctl.bat

Show queues with unacked connections like this.

rabbitmqctl list_queues name messages_unacknowledged

The output should be something like this:

VLM.eShopExample.Worker-Development 1
VLM.eShopExample.Worker-Production 0

We see that one queue has an unacked message. Let's find out the channel and associated connection that is causing the unacked message.

rabbitmqctl list_channels connection messages_unacknowledged

This returns the following output:

<rabbit@SERVER.1650192371.27249.9> 1

Ok, we found the channel that caused the problem. Let's close it. We specify the connection and a message that will be shown to the user.

rabbitmqctl close_connection "<rabbit@SERVER.1650192371.27249.9
>" "Sorry! We're closed."

We can remove the unacked message from the queue by purging it with the following command:

rabbitmqctl purge_queue VLM.eShopExample.Worker-Development

Let's run the first command again to verify that we no longer have any unacked messages.

rabbitmqctl list_queues name messages_unacknowledged
VLM.eShopExample.Worker-Development 0
VLM.eShopExample.Worker-Production 0

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
