Downtime feature release and more

Hello. CRE Miura (id:missasan) here.

For a long time now we’ve been receiving many enthusiastic requests to release a downtime function that allows the user to stop monitoring at a specified time!

Leading up until now, Mackerel has had several functions for suspending monitoring or notifications, but in order to respond to scheduled batches and maintenance etc., the use of a separate scheduler function was required like with cron for LinuxOS, taking time and effort. With the release of this downtime feature, it is now possible to set up flexible schedules from Mackerel. And of course, it can also be configured from the API.

The Mackerel team is pleased to be able to provide a function that is directly connected to saving users time and effort. In addition to this, if there are changes that you would like to see made to other functions, please feel free to send us some feedback at【】. For open source related items, pull requests are also welcome!

Now on to this week’s update information.

Downtime feature release

We’ve released a function that allows you to suspend monitoring for a specified time period, for a target service/role or monitor. Recurrence settings such as hourly, daily, weekly (day of the week), monthly, and yearly are also available.

During the downtime’s configured time period, incidents will not appear on the alert list nor will notifications be sent to the notification channel, even if there are metric posts that conflict with the target monitor. (Metrics will be posted)

As described in the following use cases, this can be used in advance for load increases or for instances when the service is known to stop.

Use cases

  • Periodic batch processing
  • Scheduled maintenance periods

How to use

Downtime can be configured in the following two ways.

  • From the console screen
  • From the API

Also in mackerel-agent-plugins v0.58.0, the -redis-namespace option has been added to mackerel-plugin-sidekiq, and the key namespace can now be specified. If you use a gem like redis-namespace to give the Redis key a namespace, you can now get metrics by specifying this option.
