Audit log source

Audited operations

Run LogQL queries or export logs using the user interface of the monitoring instance
Perform actions on the LoggingTarget custom resource
Perform actions on the LoggingRule custom resource

Audit log source	Proxy server
Log type	Data plane

Fields in the log entry that contain audit information
Audit metadata	Audit field name	Value
User or service identity	`user`	For example, "user": { "issuer": "https://ais-core.org-1.zone1.google.gdch.test", "identity": "fop-infrastructure-operator@example.com" }
Target (Fields and values that call the API)	`resource`	For example, `"resource": "/infra-obs/grafana/api/ds/query"`
Action (Fields containing the performed operation)	`action`	Possible values: `"action": "QUERY"` `"action": "CREATE"` `"action": "READ"` `"action": "UPDATE"` `"action": "DELETE"` `"action": "CREATE/UPDATE"`
Event timestamp	`time`	For example, `"time": "2022-12-02T21:37:03.657277582Z"`
Source of action	`sourceIPs` `_gdch_service_name`	For example, "sourceIPs": [ [ "10.253.165.26", "127.0.0.6" ], "_gdch_service_name": "grafana"
Outcome	`response`	For example, `"response": "Successful: 200 OK"`
Other fields	`description`	The `description` value contains the complete query. For more information. see the Example log.
