IP Intelligence Logging¶

IP Intelligence logging can be configured to view traffic matching the configured IP Intelligence policy categories. IPI logging requires F5BigLogHslpub CR configuration, enabling the Firewall section of the F5BigLogProfile CR, and IPIntelligence sub-section. The created logging profile must be associated with F5BigContextSecure or F5BigContextGlobal CRs.

CR parameters¶

The following table lists only a few parameters used in this document. For the full list of CR parameters, refer to the spec.firewall.ipIntelligence page.

Parameter	Description
publisher	Name of the Log publisher to send IP Intelligence logs. Log publisher object is of kind `F5BigLogHslpub`
translation	Enable the Log Translation Fields setting to log both the original IP address and the NAT-translated IP address for IP Intelligence log events.
aggregateRate	Sets an Aggregate Rate Limit to define a rate limit for all combined IP Intelligence log messages per second. Beyond this rate limit, log messages are not logged.

Procedures¶

Follow the steps mentioned in this section to enable IP Intelligence logging.

Apply F5BigLogHslpub CR¶

The example F5BigLogHslpub CR given in this secrion specifies a remote server with IP/port [2002::10:30:2:220]:514, and the UDP protocol.

_images/spk_info.png Note: The F5BigLogHslpub CR will be referenced by the F5BigLogProfile CR.

Copy and paste the following example into a YAML file:

apiVersion: k8s.f5net.com/v1
kind: F5BigLogHslpub
metadata:
name: "cnf-hsl-pub"
namespace: "cnf-gateway"
spec:
pool:
- name: "hsl-pool"
    endpoint:
    - "[2002::10:30:2:220]:514"
syslog:
- name: "cnf-syslog"
    format: "rfc5424"
    protocol: "udp"
    pool: "hsl-pool"

Run the following command to apply the ßF5BigLogHslpub CR.

kubectl apply -f cnf-hsl-cr.yaml

In the following example, the BIG-IP Controller logs indicate the F5BigLogHslpub CR was added/updated:

I0202 12:00:00.12347   1 event.go:282 Event(v1.ObjectReference{Kind:"F5Hslpub", F5Hslpub cnf-gateway/cnf-hsl-pub was added/updated

For more information on how to install and apply the F5BigLogHslpub CR, see F5BigLogHslpub page.

Apply F5BigLogProfile CR¶

Enable the F5BigLogProfile CR with the firewall section and IP Intelligence logging sub-section configured. Copy and paste the following example into an yaml file.

apiVersion: "k8s.f5net.com/v2"
kind: F5BigLogProfile
metadata:
name: log-profile
spec:
firewall:
    enabled: true
    ipIntelligence:
        publisher: "hsl-publisher"
        translation: true
        aggregateRate: 5000  

Run the following command to apply the F5BigLogProfile CR.
```
kubectl apply -f logprof.yaml -n <namespace>
```
Verify the F5BigLogProfile CR is applied.

For more information on how to install and apply the F5BigLogProfile CR, see F5BigLogProfile page.
