You can now select which metrics to retrieve with AWS Integration and more

Hello. Mackerel team CRE Inoue (id:a-know) here. So the cold weather has been relentless lately. Some days it feels like winter is never going to end.

Anyways, now on to the update announcements. We have a lot in store for you this week!

You can now select which metrics to retrieve with AWS Integration


Up until now, all of the metrics listed in the help page (= metrics that can be obtained with the Amazon CloudWatch API) were automatically linked with AWS integration. This didn’t require that you be aware of all these metrics, but you also couldn’t control the number of host metrics.

With this release, it is now possible to specify which metrics to integrate to Mackerel. If you have trouble controlling the host metric count, this is for you.

You can now specify the number of decimal places for numerical values displayed on widgets/custom dashboard


It is now possible to specify the number of decimal places for numerical values that are displayed on widgets available with custom dashboards. This can be particularly convenient for displaying the results of function based expressions in a numerical widget. We hope you can put it to good use!

IAM policies used with AWS Integration have been posted

A list of the IAM policies that are used with AWS Integration have been newly posted in the help page.

Please use it as a reference when creating inline policies for integration targets.

New metrics available with Microsoft Azure・RedisCache Integration

The following metrics have been added.

  • Operations Per Second
  • Operations Per Second Shard

Operations Per Second Shard is only available with plans that support shards.

Official support for Windows Server now 2012 or later

This goes hand in hand with the end of support for Windows Server 2008 R2. Be sure to check out the updated help page as well.

OSS Updates


  • [check-log] It is now possible to specify AND as a detection exclusion condition by specifying multiple --exclude


  • custom_identifier can now be configured when using Google Compute Engine instances


  • Now supported for Faraday 1.0
    • Please note that updates can not be made with Faraday 0.x

Mackerel published in CNCF Landscape!

The CNCF (Cloud Native Computing Foundation) is an organization that compiles a list of companies and OSS projects that promote cloud native.

And Mackerel was recently featured in the CNCF's Cloud Native Interactive Landscape!

We look forward to bringing you even more of the benefits of cloud native technology through Mackerel.

A new event based on “The Feedback Whiteboard” from Mackerel DAY 2!

The feedback whiteboard was one of the most popular elements featured at last year’s Mackerel Day #2 event. For me, it was really cool to see so many participants actively exchanging opinions with the Mackerel staff in front of the whiteboard.

But, I also felt like we couldn’t touch on all of the input we received that day. For this reason, we are soliciting more feedback/requests from Mackerel users and holding a discussion event with the Mackerel staff! We’re calling it Mackerel Day #2 : More Whiteboard! (Japanese only)

This will be an event centered around your opinions and requests for Mackerel. Please join us!
