Arm64 package release・Following redirects now possible for external monitoring and more

Hello. Mackerel team CRE Inoue (id:a-know) here with another update announcement.

Arm64 package released for mackerel-agent and more

An Arm64 package for mackerel-agent and various plugin packages is now officially available and can be found in the apt/yum repository (v2 repository).

Some of you may have noticed the recent increase in support for Arm architecture, for example, the release of the A1 instance by Amazon EC2. Feel free to give this a try.

Redirects can now be followed in external monitoring

External URL Monitoring lets you monitor response status codes and response times by simply specifying a URL in the Mackerel Web console. In fact, I think a lot of our users start configuring this monitoring first because it’s not necessary to install the agent.

Up until now, Mackerel's external URL monitoring specifications were to "recognize 2xx or 3xx-type responses as normal responses and not as errors" and "not to follow redirects", but this behavior has been changed. This can now be changed in settings.

Check out the help page linked below for more details.

An error message is now displayed when there is a discrepancy between the agent installation script and the OS type or version


Here’s an example of what it looks like when running Amazon Linux installation script for an Amazon Linux 2 environment.

Our support team has received numerous inquiries regarding this discrepancy, so we’ve added this as a response. Please be advised when installing.

The official command line tool mkr has been updated

Do you use mkr, Mackerel's official command line tool?

Well, it has now been updated to v0.41.0. The following changes have been made.

  • Made it easier to understand the output when running mkr hosts and no hosts exist
  • An armhf package for mkr is now generated in GitHub Releases

Thank you to all who contributed!
