We’re happy to announce the release of new muting features for Datadog monitors. Scoped monitor muting allows teams to eliminate unnecessary alerting during scheduled maintenance, testing, auto scaling events, and instance reboots. Your teams will therefore be able to filter out expected events and quickly pinpoint critical issues in your infrastructure.
Previously, monitor muting was binary: all-or-nothing. With this release, you can take advantage of Datadog tagging to mute specific scopes of a monitor on an ad hoc basis.
In addition to muting individual monitors over specific scopes, you can also schedule global downtime during a specific time window to suppress all alerting related to a tag.
For instance, if you had a planned maintenance window starting at 1am on Sunday, scheduling downtime would prevent a high volume of alerts as you bounce or redeploy the various services and instances in your environment. Plus, your team would be able to anticipate scheduled maintenance via Datadog’s event notifications and plan accordingly.
Datadog also proactively mutes monitors in response to planned downtime in certain situations. For example, monitors related to the manual reboot or shutdown of AWS instances are automatically muted, based on host statuses available via the Cloudwatch API. Similarly, monitors related to manually stopped or terminated Azure virtual machines are automatically muted based on power state annotations available from the Azure Resource Health API. Instance shutdowns that are triggered by autoscaling features are muted by Datadog as well.
Check out our API docs for more information on integrating this feature into your monitoring coverage. If you’re not currently a Datadog customer, you can sign up for a 14-day free trial of Datadog and check out this feature for yourself. Your inbox and pager will thank you for it.
