CloudGuard Rule ID: D9.GCP.LOG.08
Covered by Spectral: Yes
Category: Database

GSL LOGIC

CloudSql where databaseVersion like 'POSTGRES%' should have settings.databaseFlags contain [ name like 'log_parser_stats' and value like 'off' ]

REMEDIATION

From Portal

1. Go to https://console.cloud.google.com/sql/instances and navigate to the instance where the flag needs to be set
2. Click Edit Configurations
3. Under flags section, choose add flag, look for log_parser_stats and choose value - off.
4. Save and review your changes

From TF
Set the flag 'log_parser_stats' to 'off':

resource 'google_sql_database_instance' 'default' {
	...
	settings {
		database_flags {
			name  = 'log_parser_stats'
			value = 'off'
		}
	}
}

From Command Line

1. First retrieve all existing flags values:

gcloud sql instances describe INSTANCE_NAME

2. Add all existing flags and their value to the patch request - otherwise they will get set to their default value.

gcloud sql instances patch INSTANCE_NAME --database-flags (ExistingFlag1=Value1,ExistingFlag2=Value2,...),log_parser_stats=off
