AWS Step Functions Integration release and more

Hello. Mackerel team CRE Inoue (id:a-know) here.

It is hot outside! For the past week, I’ve been rotating through the same Mackerel T-shirts and polo shirts to try and keep cool. Is summer only going to get hotter from here on out? I'm a little worried.

Now then, on to this week’s update information.

AWS Step Functions Integration release

AWS Step Functions is now supported as as a feature of AWS Integration!

With Integration configured, 1 State Machine can be registered as 1 Micro host in Mackerel (refer here for more on Micro hosts). The formula used to calculate the metric count is 7 + 9 × (number of activities) + 8 × (number of Lambda functions).

Coincidentally, AWS Step Functions is also used in the backend of Hatena Blog, a service provided by Hatena, so there was a lot of excitement in the company over the support for this integration. We definitely recommend all of our Mackerel users to give it a try!

When Anomaly Detection for Roles/training fails, the reason is now displayed

Have you all gotten the chance to try out the recently released public beta version of our new function Anomaly Detection for Roles?

There have been some cases of the training using machine learning algorithms failing under certain conditions, but today's update makes it possible to understand why the training failed.

The Anomaly Detection for Roles function has been highly praised as being effective for understanding workload characteristics such as these, and for helping make monitor configurations more complete. It’s also very easy to set up, so be sure to give it a try if you haven’t already!

“The Confused Deputy Problem” for AWS Integration has been resolved

The External ID for the AWS Integration configuration IAM role is now issued at random.


This solves "The Confused Deputy Problem" and improves the security of integrated roles. You can also improve security by issuing and configuring an External ID for existing AWS Integration configurations.

We’ve also updated the description for the configuration method in the help page, so be sure to give that a second look.

Along with EOL, official support for Ubuntu 14.04 LTS has ended

Along with the support that ended on April 30th of this year, the official support for Ubuntu 14.04 LTS has also ended with Mackerel. Check out the help page linked below for all the officially supported environments.

Other updates

Due to the large number of update content today, I’ll simply list the rest below. - The entry method for credit card information has changed - The card number entry is now easier to understand and more secure than ever. - Changes have been made to the plan page, so that standard hosts and micro hosts that exceed the metric limit can be checked individually

At the event, they will be talking on "Mackerel's Dashboard Renewal" and "Creating a character for Mackerel's container-agent". It’s not often that you get the chance to hear directly from the designers regarding their designs and user-friendliness, so if you’re interested, by all means!
