When Searching Amazon Athena for Service events

Here is a quick query when you are looking for events in CloudTrail. First, export to Athena.
Then create a query that references the table: Now you are ready for some SQL

In the example below I am getting entries from “TableName” and the service is Amazon WorkSpaces. That has a source of

FROM TableName
WHERE eventsource = '' 
ORDER by eventtime
LIMIT 100;

Monitor your WorkSpaces using CloudWatch metrics

WorkSpaces and Amazon CloudWatch are integrated, so you can gather and analyze performance metrics. You can monitor these metrics using the CloudWatch console, the CloudWatch command line interface, or programmatically using the CloudWatch API. CloudWatch also allows you to set alarms when you reach a specified threshold for a metric.

For more information about using CloudWatch and alarms, see the Amazon CloudWatch User Guide.


To get CloudWatch metrics, enable access on port 443 on the AMAZON subset in the us-east-1 Region. For more information, see IP address and port requirements for WorkSpaces.

Relative Mouse Offset

Relative Mouse Offset
By default, during users’ streaming sessions, AppStream 2.0 transmits information about mouse movements to the streaming instance by using absolute coordinates and rendering the mouse movements locally. For graphics-intensive applications, such as computer-aided design (CAD)/computer-aided manufacturing (CAM) software or video games, mouse performance improves when relative mouse mode is enabled. Relative mouse mode uses relative coordinates, which represent how far the mouse moved since the last frame, rather than the absolute x-y coordinate values within a window or screen. When relative mouse mode is enabled, AppStream 2.0 renders the mouse movements remotely.

Users can enable this feature during their AppStream 2.0 streaming sessions by doing either of the following:

Pressing Ctrl+Shift+F8

Choosing Relative Mouse Position [Ctrl+Shift+F8] from the Settings menu on the AppStream 2.0 toolbar in the top left area of their streaming session window. This method works when they use classic mode or Desktop View.

How to find instances available in the AWS LAX Local Zone

I recently needed to create a custom xml file to configure the instance types available in the LAX local zone for a Citrix Virtual Apps Deployment. In AWS parlance, you are looking to “Find an Instance type using the AWS CLI” This is what the command looks like for the LAX 1a local zone:

aws ec2 describe-instance-type-offerings --location-type "availability-zone" --filters Name=location,Values=us-west-2-lax-1a --region us-west-2

If you are looking in LAX 1b:

aws ec2 describe-instance-type-offerings --location-type "availability-zone" --filters Name=location,Values=us-west-2-lax-1b --region us-west-2

Example output from the LAX 1a local zone

Chromebook Shortcut to Display Settings

Do you ever move your Chromebook place to place with a variety of display / monitor arrangements? I do. So I wanted a shortcut to the Display settings.


This probably won’t work in your browser as a link from this page. Just copy this link and paste it into your browser or create a bookmarks bar shortcut.

I leave the Name blank so there will be just a gear icon with no text in the bookmarks bar.

You can also use:


Whatever is faster or easier for you.
