Monitor Azure events with Logic Apps – follow up

Following on from my earlier post “Monitor Azure events with Logic Apps” I’ll now show how to add additional control within the Logic App to only alert on events related to virtual machine changes and how to surface additional event information in the email.

Firstly edit the Logic App in the designer and click the + between the event and email steps and choose Add an action.

EG0

From the Choose an action screen select Control.

EG1

Select Condition.

EG2

Click into the “Choose a value” box, select Expression and enter triggerBody()?[‘data’][‘operationName’] and click ok.

EG3

In the next box select “is equal to” and in the value box enter Microsoft.Compute/virtualMachine.

EG4

Drag the “Send an email” action into the “If true” box.

EG5

These changes ensure the Logic App will only send an email for operations related to virtual machines.

If you would like to include additional event information in the email beyond those in the Dynamic content selection it’s easy to achieve.  From the Logic App page click on runs history.  Click on “When a resource event occurs” and you can see the JSON on the event. Click “Show raw outputs” to see the full JSON generated by the event.

EG56

You can include values from the JSON in the email using the expression box.  Go back to the “Send an email” action and click on the email body.  In the Expression box enter the path to the JSON value, e.g. triggerBody()?[‘data’][‘operationName’] to include the operation name or triggerBody()[‘data’][‘claims’][‘http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name’%5D to include the name of the user that carried out the action.

Office 365 ProPlus installation detection with System Center Configuration Manager (SCCM)

Microsoft have a good guide showing how to deploy Office 365 ProPlus with System Center Configuration Manager (SCCM), see here.  Within the guide there’s a section  showing the detection rule to use.  However, I’ve found the registry detection method doesn’t work and Office 365 ProPlus will install, but Software Centre will show the installation as failed.

The Microsoft guide has the following configuration, which I’ve found to not work.

O365PP0

This is the detection method I use.  If you update the detection method, run a machine policy retrieval & evaluation cycle on an affected machine to test the change.

Monitor Azure events with Logic Apps

In this post I’ll provide a starting point for monitoring Azure with Logic Apps whereby an email is sent when a successful change is made within an Azure subscription.

To start with, check the Event Grid resource provider is registered within your Azure subscription.  You can do this in the Azure portal under Subscriptions -> Resource providers.

EventGrid0

Next, create a Logic App from the Azure portal, entering a name, resource group and location.

EventGrid1

From the splash screen select the common trigger When a Event Grid event occurs.

EventGrid12

Click the sign in button to connect to your Azure subscription.

EventGrid13

Select your Azure subscription, resource type and resource name.  In this example I’ve selected the subscription, for event monitoring across the entire subscription, but you can choose resource group or something else to scope the alerts further.  I’ve also added an event type filter for WriteSuccess, but again you can adjust as per your requirements.

EventGrid14

 

In this example I’ve chosen to be notified by email, so click on new step, then select Office 365 Outlook, followed by send an email.

EventGrid15

Populate the email body with event information that interests you.

EventGrid16

 

Save the Logic App, then make a change, e.g. resize a VM or create a resource within the subscription to trigger the alert.

If you don’t receive an email check the runs history on the Logic App page.

EventGrid17

If nothing is listed check that the Logic app automatically created the Event Grid subscription.  Search for Event Grid subscriptions in the Azure portal.

EventGrid18

If nothing is listed re-register the EventGrid resource provider in your Subscription.  I did this using Azure Cloud Shell Register-Azure RmResource Provider -ProviderNamespace Microsoft.EventGrid.

EventGrid19

Once you have the basics working you can customise further, e.g. to only notify for changes related to virtual machines.  In a future post I’ll show how to do this.

Renaming Azure automation accounts

As of Aug 2018 it’s not possible to rename an Azure automation account, but this is the next best thing.  There are number of limitations to this approach, including the requirement to recreate schedules and a number of other automation account settings and configurations, but if you have a simple setup it’s worthwhile.

  • Bulk export the runbooks from the incorrectly named automation account using the Export-Azure RmAutomation Runbook PowerShell cmdlet.
  • Create a new automation account with the desired name.
  • Bulk import the exported runbooks into the new automation account using the Import-Azure RmAutomation Runbook PowerShell cmdlet.  Use the -Published switch to save time having to manually publish each runbook post import.
  • Recreate and link any schedules and other configurations.
  • Import any modules required by your runbooks.
  • Update the existing modules as they’re not the latest available when you create the account.

 

 

 

 

Working with Azure tags in Power BI

Using tags in Azure is a great way to logically organise resources by categories.  Combining tags with the Power BI Microsoft Azure Consumption Insights connector should offer a powerful way to analyse and gain insights into your Azure expenditure.

AzurePowerBI1.png

Unfortunately, the connector imports the tags as a single field containing the tagging JSON, which makes it difficult to work with the tags in a meaningful way.  For example, if you have tags called System, Geography and Environment it would be great to be able to work with these in Power BI as an individual fields.  Fortunately, this is possible, but not with Power BI in the browser.

Download Power BI Desktop  and get data from the Microsoft Azure Consumption Insights (Beta).

AzurePowerBI2

Enter your EA enrollment number, which you can get from https://ea.azure.com/ .  You’ll also need an API access key, which is available from https://ea.azure.com/ under reports -> download usage -> API access key.

Select UsageDetails, then right-click and select edit.

AzurePowerBI3

If you’ve only recently added tags order the data by date descending.  This is because the Power BI editor loads 1000 rows initially and if you’ve only recently started using tags they’ll only be listed against recent records.

Find the Tags column, right-click choose Transform, followed by JSON.

AzurePowerBI4

Power BI will now parse the JSON and enable you to split out each tag into a separate column.  Click on the arrows and the tag fields will be loaded.

AzurePowerBI5

AzurePowerBI6

Click ok to add the new tag fields to the data set, followed by close & apply.

AzurePowerBI7

You can now work with each tag individually.

Mirrored SQL Databases Stuck In Recovery Mode

Following a server restart, two of three SQL Server databases in a SQL Server Database Mirroring configuration were stuck in recovery mode on the primary server.

Running sys.dm_tran_locks showed a session with a resource_database_id for each of the databases stuck in recovery.

It appeared that SQL Server Database Mirroring was preventing the recovery process completing on the two databases following the server restart.

The resolution was to stop and start the database mirroring endpoints on the primary and secondary SQL Servers.  To return a list of endpoints run select * from sys.endpoints.

To stop and restart the endpoints run

ALTER ENDPOINT %ENDPOINT NAME% STATE=STOPPED

ALTER ENDPOINT %ENDPOINT NAME% STATE=STARTED

Windows 10 April 2018 Update (1803) fails to install with error 0x87D0070C

When deploying the Windows 10 April 2018 Update (1803) via SCCM the update fails to install with error 0x87D0070C.

1803-0

In Event Viewer you see the error “Installation Failure: Windows failed to install the following update with error 0x800704C7: Feature update to Windows 10 (business editions), version 1803, en-gb.”

The error is caused by the default maximum run time setting in SCCM of 60 mins, which in this case is insufficient for the update to install and it times out.  To increase the timeout value, find the update within the Software Updates section of SCCM, right-click on the update and select properties.

1803-1

Increase the value to something like 240 mins and click OK.
