After you have set up and configured RPZs and RPZ rules, you can verify whether the RPZ zone transfers are functioning properly by doing the following:

The appliance also makes a syslog entry, when an RPZ zone refresh succeeds or fails and also sends an SNMP trap and an email notification, if configured. For information about setting SNMP and email notification, see Setting SNMP and Email Notifications.

Viewing RPZ in the Syslog

To receive RPZ information in the syslog, make sure that you enable the RPZ option in the Logging tab of the Grid DNS Properties editor. Once the RPZ option is enabled, the appliance logs RPZ threats in CEF (Common Event Format) in the syslog. You can click the Action icon to view the RPZ threat details in the RPZ Threat Details viewer. For information about how to configure the syslog server, see Using a Syslog Server.

Following is a sample RPZ threat message:

Each log message contains the following information:

The timestamp when the event happened in yyyy-mm-ddThh:mm:ss-00:00 format.
Infoblox|NIOS |x.x.x: Indicates the Infoblox product, and x.x.x represents the NIOS version.
The string following the NIOS version is a hard-coded constant. In this example, it is RPZ QNAME.
The hard-coded constant is followed by mitigation action. In this example, it is PASSTHRU.
The number following the mitigation action is the threat severity level. The following numbers indicate the severity levels:
- 8 = Critical
- 7 = Major
- 6 = Warning
- 4 = Informational
dst: Destination IP address.
src: Source IP address.
spt: Source port.
view: DNS view.
qtype: Query type.
msg: RPZ rule.

The syslog messages are optionally tagged according to the logging category configured in the external syslog servers. For more information, see Syslog Message Prefixes.
To verify RPZ zone transfers:

Go to the Administration tab -> Logs tab -> Syslog tab.
Select RPZ Incident Logs from the Quick Filter drop-down list.
Review the syslog for zone transfer confirmation, as shown in the below figure.
