You can suppress alerts for many assets at once at the inventory level. The rules for when a particular alert is suppressed are dependent on the alert’s category and type, the established suppression rules, and whether the asset belongs to more than one inventory.

Consider an alert of category C for asset A:

If category C alerts are suppressed for asset A, the alert is suppressed.
If category C alerts are suppressed for every inventory that contains asset A, the alert is suppressed.
Otherwise, the alert is not suppressed, and notifications will be sent as usual.

Let’s say your portfolio is configured as follows:

Inventory Beacons has one asset: prefix 84.205.64.0/24
Inventory OurStuff has two assets: prefix 17.54.0.0/16 and prefix 84.205.64.0/24
You have suppressed upstream alerts in inventory OurStuff.
You have suppressed instability alerts in inventory Beacons.

Here are how some example alerts will play out under this configuration:

Alert Outcome Reason
outage

84.205.64.0/24

Not Suppressed Category outage is not suppressed at any level.
new-upstream

17.54.0.0/16

Suppressed The sole inventory that contains 17.54.0.0/16 suppresses upstream alerts. New-upstream is in the category upstream.
instability

84.205.64.0/24

Not Suppressed 84.205.64.0/24 belongs to two inventories, only one of which (Beacons) suppresses instability alerts.
