Today marks the first day of April.
At Hatena, new employees have entered the company and things have become a bit more lively.
Here is this week’s Mackerel update (don’t worry, even though today is April fools’ day, everything in this article is true).
An API to update hosts’ roles
In the past, you could add roles from the host information updating API, but considering the possibility of a collision with the changes in the Web screen, removal was not possible.
With this update, the API was supplemented in order to update role configurations related to the host, including the possibility of removing the role.
PUT /api/v0/hosts/<hostID>/role-fullnames
By specifying the following format for hosts whose roles you want to configure, role information will be updated.
{
"roleFullnames": [ <string>, <string>, … ]
}
For more details, take a look at the help page.
Official support for Amazon Linux
In last week’s announcement, we informed you about mackerel-agent not working in Amazon Linux AMI 2016.03.
After that, we implemented an emergency response, resolved the problems, and introduced the official support for Amazon Linux in Mackerel.
The Amazon Linux installation procedure is described from Mackerel’s host registration guide screen(https://mackerel.io/my/instruction-agent).

In this change, the blog and help page have become “https” format. Accessing the old URL will redirect you to the new, but a registration change of the RSS reader and such should be done as necessary.

Introducing user blogs
User entries are being sporadically introduced*1 in Mackerel Blog.
Here are user entries about a convenient way to use Mackerel and a new user-developed plugin. Unfortunately, they are only available in Japanese.

プロセスのメモリ使用量とCPU使用率などが取れる mackerel-plugin-linux-proc-stats をリリースしました - tkuchikiの日記
Being able to transfer instantly, such as to a specific host page, with Alfred Workflow seems convenient right?
Recently, i’ve gotten used to Spotlight on Mac, but I think I want to give this a try.
