Monitoring a Virtual Machine in Azure

This is my first entry in English so I would like to apologize upfront if there are any language mistakes. If you find anything that needs correction, please feel free to contact me and I will gladly make the changes based on your suggestions

In the same way we monitor our physical servers, it is necessary to monitor our VM.

Now that we have a Virtual Machin in Azure, I will explain how to enable and configure how to monitor it.

For that, I will use the new Azure Portal, Ibiza. It stills in Preview, but it is functional.

This is the URL

To configure the monitoring it is necessary an Azure Storage Account where the monitor data will be stored, so the first step is to create a Storage Account in the same region that our VM is.

Go to Browse and select Storage Accounts. You can see there is another section called Storage Accounts (Classic). There you can find the Storages Accounts created in the old Portal.

Once in the Storage Accounts section, press ADD

A new slide appears. Here we assign a name to the Storage Account and select the Resource Group and the Location (remember, the Location must be the same where the VM is).

In the upper right corner, with the BELL symbol, you can watch the progress of the deployment.

When the deployment is finished, just refresh with the circular arrow

We can configure the VM monitoring yet. In our case, we will find it in Virtual Machines (classic) because it was created in the old Portal.

Click on the VM and a slide appears. Here we can see the all the data about the VM and another slide with the settings. In the lower part there is a tile called Monitoring where there is a message offering to turn on the diagnostics, but we are going to use the Diagnostics menu item in the right.

In the new slide, press ON to enable the diagnostics options. The first thing is to select the Storage Account configured previusly.

And then, select the parameters we want to monitor.  In this case, we are not going to monitor .NET, SQL or IIS. But remember to check the Boot Diagnostics. And when you have finished of choice the options you want to monitor, press SAVE.

Now we can start the VM and wait for the data to see the charts change.

We can add some alerts now. They are useful to be aware of some important metrics of our VM. Press on Alert Rules and then Add Alert.

In this example, it will send an email to the EMAIL@EMAIL.COM address when the percentage of memory used is greather than 80% for 5 minutes.
