Returns a group of values you specify to query the server for matching alarm instances.
Wire this cluster to Query Filter to search the server.
Property | Description | Example |
---|---|---|
alarm id | Unique identifier for a process or condition tracked by an alarm. | System.Health.DiskSpaceLow.Bdd9u!4aMd!$pYrf*CnaIZ2tbu$-Ct%? |
acknowledged after | Timestamp representing the earliest time to return alarm instances for. The server returns alarm instances your team acknowledged between acknowledged after and acknowledged before. | 2019-01-14T23:15:53.7270539Z |
acknowledged before | Timestamp representing the latest time to return alarm instances for. The server returns alarm instances your team acknowledged between acknowledged after and acknowledged before. | 2019-01-15T23:15:53.7270539Z |
channel | Resource associated with the alarm. For example, if an application sets an alarm because a wireless network went down, the channel could be the name of the network and the resource type classifies the alarm as the network. | CRIO1.System.Health.DiskSpaceUsePercentage |
created by | Identifier for who or what created a given alarm instance. This property normally identifies the rule engine that requested an alarm instance be created. | TagRuleEngine |
current severity level max | Highest current severity level you want to return alarm instances for. The server returns alarm instances with current severity levels between current severity level min and current severity level max. | 3 |
current severity level min | Lowest current severity level you want to return alarm instances for. The server returns alarm instances with current severity levels between current severity level min and current severity level max. | 2 |
description | Notes you gave an alarm instance. | Disk space on tester-1 is high. Disk usage was 95% when this alarm was created. |
display name | Title you gave the alarm instance. | Low disk space on tester-1 |
highest severity level max | Highest severity level an instance ever reached. The server returns alarm instances with severity levels between highest severity level min and highest severity level max. | 4 |
highest severity level min | Highest severity level an alarm instance ever reached. The server returns alarm instances with severity levels between highest severity level min and highest severity level max. | 2 |
is acknowledged | Enum that determines whether to return acknowledged, unacknowledged, or all alarm instances. | Any |
is active | Enum that determines whether to return active, inactive, or all alarm instances. | False |
is clear | Enum that determines whether to return cleared, active, or all alarm instances. | True |
occurred after | Timestamp specifying when an alarm instance occurred. The server returns alarm instances with timestamps between occurred after and occurred before. | 2019-01-14T23:15:53.7270539Z |
occurred before | Timestamp specifying when an alarm instance occurred. The server returns alarm instances with timestamps between occurred after and occurred before. | 2019-01-15T23:15:53.7270539Z |

properties | Key-value pairs associated with an alarm instance. | Slot Number = -1 |
resource type | Type of resource associated with the alarm. For example, if an application sets an alarm because a wireless network went down, the channel may be the name of the network where the alarm triggered and the resource type may classify the alarm as the network. | Network |
