Alert status can now be selected when an alert occurs with host connectivity monitors and more

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

Alert status can now be selected when an alert occurs with host connectivity monitors

Among the various monitors that can be configured with Mackerel, ‘Host connectivity monitoring’ can detect when metric transmission from the agent (mackerel-agent) gets interrupted and issues an alert. However up until now, the status of this alert was fixed to critical. With this update, it is now possible to choose the status of an alert when it occurs.

Some users may not even be aware of host connectivity monitoring due to the fact that it’s already configured from the get-go. We recommend reviewing the page linked below.
