Before doing this you need to configure AzureWatch to point to your Azure subscription.

Local Perfmon

The Control Panel client version of AzureWatch uses your local Perfmon (where the tool is running) to display counters.  So you can go to Perfmon and add all instances of the AzureWatch counters if you choose to view it there instead of using AzureWatch.

 

How to View an Azure Queue

Go to Raw Metrics, right click on Managed Queue Counters and add the queue to be viewed.

Once you assign the raw metric of the queue, bring up Aggregated Metrics for the role that will be writing to the queue. Right click and add new Aggregate. Use a value of 2 mins for queues (5 mins for perfmon counters) and ‘Use latest value’.

Click on Publish Changes and wait a few minutes.

Within AzureWatch click on Metrics View – Live to see the current number of items in the queue.

Using Perfmon Counters

Simple formula to remember

  1. Create a Raw Metric
  2. Create an Aggregate
  3. Create a Rule

For the desired role click on Raw Metrics.

In the Raw Metrics Window right click on Managed Performance Counters and select Add New.

In the Performance Counter Properties dialog choose the category and the counter. When you hit okay it should now show up in the Raw Metrics box.

To create an aggregate, choose the raw metric you just created, calculate an average, and use 5 mins interval for perfmon.  Click OK.

Click Rules under the instance you want to monitor, right click New to bring up Rule Edit box.

Add a Boolean expression to trigger an alert.  You can make this as simple or complex as you like. Here I am using 20% to make the perfmon counter trigger. It will send an email to my account (configured earlier in Azure setup) and I can also choose to do autoscaling. Here I have arbitrarily decided to scale down (by one instance) since its faster than scaling up for demo sake.

Click OK and Publish Changes.

Start the app you are monitoring and view the counters either in Perfmon or in AzureWatch.

You should also have an email notification sent to the email address you configured at the start. The rules will be evaluated in order and once the first one is found it will trigger. Here I had previously configured a rule to trigger when the ASP Requests Queued was >5.

All known parameter values:

Avg5UnresponsiveInstanceCount: 0; (metric count: 5);
MikeRequestsQueued: 0; (metric count: 7);

You can also view the perfmon counters in the Dashboard view which shows each role and its corresponding items being monitored.

Window Management

Moving the windows and displaying them was a bit of  a challenge. For some reason I did not have a menu bar show up on my display.  When you start up the Explorer window is present and that’s what you need to view the other windows. If you close it down without the menu there is no way to bring it b back up except restart the tool. Clicking on the items in the Explorer window brings up their corresponding windows.  If you grab it and drag it a cross with arrows appears to allow you to move it to the location you desire by dropping it on one of the arrows.

Here I am dragging the explorer window to drop it on one of the arrows.

 

Instance Scaling Limits

You can configure the monitored app to not scale past or below a certain # of instances.

From the Explorer window double click on one of the roles.

Enter a minimum or maximum number of instances regardless of the rules you have configured. Remember in the rules you can scale up or down when the rule is true.
