The event muting feature allows you to control how Blue Matador creates events based on resources, projects, and monitors for a specified time. Some use cases of event muting include:
Silencing notifications for a few hours when working on production
Hiding events for your dev environment permanently
Scheduling recurring maintenance windows
Blue Matador’s monitors have automatically configured thresholds and settings that cannot generally be updated. When you want to purposely mute or hide events for specific resources, monitors, or periods of time, you can configure mute rules. You can access mute rules via Setup -> Mute Rules.
On the mute rules page you can view all of your active and inactive mute rules. A mute rule will show up in the active view if all of the following criteria are met:
The resource(s) for the rule is still active in your account
The period for the rule is either forever, currently in progress, or scheduled in the future
The rule has not been disabled
Any rules which affect deleted resources, have a period that occurred in the past, or have been disabled will be inactive and will not affect future events.
Mute rules have two modes: Mute and Mute + Hide. An event that is muted will display in the Dashboard and Timeline views of the app, but will not cause notifications when they are created. An event that is muted and hidden will not display on the Dashboard at all, and is hidden in the Timeline by default. Hidden events can be displayed in the Timeline by selecting the Show Hidden option on the Timeline. This option only appears if there are hidden events within the time range and filters you have selected.
When an event is created, Blue Matador checks the affected resource and event type against any active mute rules in your account. Any matching rules are used to mark the event as muted. In accounts that use projects, the event will be muted if any of its projects match any of the projects in a mute rule. If both a Mute and a Mute + Hide rule match an event, the Mute + Hide rule will take precedence and the event will become hidden.
When an event becomes muted or hidden, it stays permanently muted or hidden for the life of the event. If you disable a rule, or the period of the rule passes, the affected events do not become un-muted or un-hidden. However, future events will always be evaluated using the active rules at the time the event is created.
If an event becomes muted or hidden after it has already created a notification to an incident management integration such as PagerDuty, OpsGenie, or VictorOps, the event will not resolve the related incident immediately in Pagerduty, OpsGenie, or VictorOps; it will still resolve the related incident in PagerDuty, OpsGenie, or VictorOps when the event itself resolves.
You can create a mute rule from the Mute Rules page. Mute rules can also be created from the Timeline, Resources, and Monitors pages. When creating a mute rule from the Mute Rules page, you must select the affected resources and monitors, specify the period of time the rule will be active, and decide whether matching events will be muted, or muted and hidden.
Go to the Mute Rules page via Setup > Mute Rules
Click the Create Rule button to open the Mute Events modal
Click Choose Resources to open the resource selector
If your account has projects set up, you can use the projects dropdown to select which projects will be affected by the rule
Selecting All Resources means the rule will affect every current and future resource in your account
Click Done to finalize the resource selection
Click Select Monitors to open the monitor selector
If you select All Monitors, then all current and future Blue Matador monitors will be affected
If you select the check box next to a service name, then all current and future monitors for that service will be affected
You can expand one of the services to select specific monitors that will be affected in each service
Click Done to finalize the monitor selection
Click Specify Time to open the period selector
If you select Forever, then the rule will apply until it is disabled. Currently open events matching the resources and monitor selections will also be affected
If you select For X hours, then the rule will apply for a limited amount of hours starting when the rule is saved. Currently open events matching the resources and monitor selections will also be affected
You may also schedule the period in the future. Using this method, use the date and time picker to specify the time range of the first occurrence. If this period should repeat, then check the box and specify the value for Repeat every X days. Currently open events will not be affected by a rule created using a scheduled period, regardless of the repeat setting.
Then, select the muting mode
Mute means that events will be created normally, appear in the Dashboard and Timeline, but will not cause notifications through your notification integrations
Mute + Hide means that the events will be created as hidden, which means they will not appear in the Dashboard, and do not appear in the timeline by default. They will also not cause notifications through your notification integrations
When specifying resources using projects, events will be muted/hidden for those projects, but may still cause notifications and appear in the Dashboard if the event resource belongs to multiple projects and is not muted/hidden for every project it belongs to.
Finally, click Save to save the mute rule
Once a mute rule is created, it cannot be edited. We prevent editing because it is unclear what should happen to matching events when modifying an existing mute rule with respect to the period that has been specified. Instead, you can disable and clone a mute rule to get a different configuration.
Disabling a mute rule will cause future events matching that rule to no longer match. Those events may still become muted by matching other active rules. Currently muted or hidden events that were affected by the newly disabled rule will not be un-muted or un-hidden. Disabling cannot be undone, but a similar effect can be achieved by cloning a disabled rule.
Both active and inactive rules can be cloned. Cloning a mute rule will open up the Mute Events modal with information pre-filled from the source mute rule. The time period will be filled out with the source rule’s configuration, but the current time is used when deciding which events will match the period portion of the rule.
Events can be muted directly from the Timeline view. When muting from the Timeline, the resource and event type options are automatically filled out with the values from the event, but can still be changed.
View your Timeline via Explore > Timeline
Select an event that you wish to mute to view the details pane
Click the Mute icon at the top of the details pane to open the mute modal
Configure the period and select the mute mode, then click Save
Events can be muted from the Resources view. This allows you to specify a mute rule for a specific resource, which is not allowed from the Mute Rules or Monitor view.
View your Resources via Explore > Resources
Use the Filter dropdowns and search box to find your resources, then expand all resources. Then, click the Mute button next to your resource.
Fill out the event type, period, and mute mode, then click Save
Events can be muted from the Monitors view. This method can be used to mute monitors without having an event for that monitor in the Timeline, even if there is no data for that monitor.
View your Monitors via Explore > Monitors
Use the dropdowns to filter the monitors and find the one you wish to mute. Then use the menu on the right-hand side of the monitor and select the Mute option.
Fill out the resources, period, and mute mode, then click Save
Are currently open events modified when I create a mute rule? A mute rule will only modify current events if its period is set to Forever or For X hours.
What is the difference between mute and hide? When events are muted, notifications will not be created for them via Slack, PagerDuty, OpsGenie, VictorOps, AWS SNS, Email, etc. When events are hidden, notifications will also not be created, and the events will not show up in the Dashboard or Timeline.
Does muting work with projects? The muting feature is fully compatible with projects. When configuring a mute rule using projects, an event with any projects matching any of the projects in the mute rule will be affected by the rule.
