Jira Service Management has been added to the notification channel.
With the End of support for Opsgenie, we've added Jira Service Management (JSM) as an alternative notification channel. JSM is a service management tool provided by Atlassian, and like Opsgenie, it offers incident management and alert notification capabilities.
Select "Jira Service Management" from the notification channel creation page and enter the required information to enable alert notifications from Mackerel to JSM. For details on the settings, please see the Help page.

The new host registration screen has been revised to make the OS options easier to understand.
Previously, the OS names supported by Mackerel's package management system were limited and confusing. We've reorganized and expanded the options so that available OSes are clear at a glance. This makes it easier to find the optimal installation procedure for your host.

AWS WAF Classic support has ended in AWS Integration.
As previously announced, we have ended support for AWS WAF Classic. If you are still using AWS WAF Classic, please consider migrating to AWS WAF.
Thank you for your understanding.
