Observation Schema
You can refer to this observation schema to configure the payload template for a third-party templated connection.
Alert Logic generates an observation when it detects an occurrence of a log correlation rule. For more information, see Correlations and Notifications.

}Definitions
- fields (object)
authority (string) – Alert Logic subsystem and component that generated the observation
class (string) – Major classification of the observation, the value of which depends on the taxonomy selected for the observation
confidence (number) – True positive detection confidence expressed as a number between 0 and 100, representing a rounded whole number percentage. A value of 100 equals 100 percent true positive detection.
desc (string) – Observation description
- end_ts (number) - Epoch time stamp when the last log message triggering this correlation observation occurred
ingest_id (binary) - Unique log message identifier
ingest_ts (number) - Epoch time stamp (GMT) indicating when Alert Logic processed the log message
keys (object) - Set of token-type values that uniquely identify an instance of this observation type
- message (string) - Details about the observation instance
time_recv (number) - Epoch time when Alert Logic detected the observation instance
- message (string) - Details about the observation instance
-
parents (array of strings) - References to data records that contributed to the generation of this observation and can be used to navigate to the log search used for the log correlation rule
- path (string) - Unique logical name and path of the observation in the Alert Logic console
-
properties (object) - Set of token-type values that capture additional information about the observation
-
recommendations (string) - Full text of the recommended actions for this observation or incident
-
severity (string) - Importance of this observation with respect to the risk to the customer's environment
Valid values:
critical,high,medium,low,info - start_ts (number) - Epoch time stamp when the first log message triggering this correlation observation occurred
-
subclass (string) - Minor classification of the observation, the value of which depends on the taxonomy selected for the observation
- summary (string) - Summary of the observation
-
tactic (string) - Determined MITRE ATT&CK tactic based on its detection within the customer's environment
-
technique (string) - Determined MITRE ATT&CK technique based on its detection within the customer's environment
-
ts (number) - Epoch time stamp (GMT) indicating when the observation observation was generated
- visibility (string) - Defines who can see the observation in the system and is used for notification and incident generation
- id (object) - Information about the observation returned by the search service
account (number) - Customer account identifier
aid (number) - Internal audit ID
msgid (string) - Observation message identifier
- extra (object) - Additional information about the observation
customer_name (string) - Customer name of the Alert Logic account where the observation was generated
observation_description (string) - Observation description in HTML format
correlation_rule_id (string) - Unique identifier of the log correlation rule that generated the observation
correlation_rule_name (string) - Name of the log correlation rule that generated the observation
observation_id (string) - Identifier of the observation
deployment_name (string) - Name of the deployment in which the observation occurred
- tld (string) - Top-level Alert Logic domain for the customer based on the region in which the data resides.
