Manage Alert Notification Silencing Rules

From the Cloud interface, you can manage your space's Alert notification silencing rules settings as well as allow users to define their personal ones.

Prerequisites

To manage space's Alert notification silencing rule settings, you will need the following:

• A Netdata Cloud account
• Access to the space as an administrator or manager (troubleshooters can only view space rules)

To manage your personal Alert notification silencing rule settings, you will need the following:

• A Netdata Cloud account
• Access to the space with any role except billing

Steps

1. Click on the Space settings cog (located above your profile icon).
2. Click on the Alert & Notification tab on the left-hand side.
3. Click on the Notification Silencing Rules tab.

4. You will be presented with a table of the configured Alert notification silencing rules for:

   • The space (if you aren't an observer)
   • Yourself

You will be able to:

1. Add a new Alert notification silencing rule configuration.
   • Choose if it applies to All users or Myself (All users is only available for administrators and managers).
   • You need to provide a name for the configuration so you can easily refer to it.
   • Define criteria for Nodes, to which Rooms will the rule apply, on what Nodes and whether or not it applies to host labels key-value pairs.
   • Define criteria for Alerts, such as Alert name is being targeted and on what Alert context. You can also specify if it will apply to a specific Alert role.
   • Define when it will be applied:
     • Immediately, from now until it is turned off or until a specific duration (start and end date automatically set).
     • Scheduled, you can specify the start and end time for when the rule becomes active and then inactive (time is set according to your browser's local timezone). Note: You are only able to add a rule if your space is on a paid plan.
2. Edit an existing Alert notification silencing rule configuration. You will be able to change:
   • The name provided for it
   • Who it applies to
   • Selection criteria for Nodes and Alerts
   • When it will be applied
3. Enable/Disable a given Alert notification silencing rule configuration.
   • Use the toggle to enable or disable
4. Delete an existing Alert notification silencing rule.
   • Use the trash icon to delete your configuration
