Views

This section provides information about views within Oracle Resource Analytics Networking and their columns data types, keys, and the referred view and column names. The following views are available:

Networking Views
Name	Description
VCN_CAPTURE_FILTER_DIM_V	This view stores information on capture filters, which contain a set of rules governing what traffic is mirrored for a VTAP or captured for a VCN Flow Log.
VCN_DHCP_OPTIONS_DIM_V	This view stores information on DHCP options, which are used by the VCN to automatically provide configuration information to the instances when they boot up.
VCN_DIM_V	This view stores information on the properties and configurations of virtual cloud networks (VCN).
VCN_INTERNET_GATEWAY_DIM_V	This view stores information on internet gateways, which represent a route that connects the edge of a VCN with the Internet.
VCN_IPV6_DIM_V	This view stores information on IPv6 addresses and their related properties.
VCN_LOCAL_PEERING_GATEWAY_DIM_V	This view stores information on local peering gateways (LPG) which are objects on a VCN that let the VCN peer with another VCN in the same region.
VCN_NETWORK_SECURITY_GROUP_DIM_V	This view stores information on network security groups (NSG) which provide virtual firewall rules for a specific set of VNICs in a VCN.
VCN_PRIVATE_IP_DIM_V	This view stores information on the configuration of private IPs.
VCN_PUBLIC_IP_DIM_V	This view stores information on the configuration of public IPs.
VCN_ROUTE_TABLE_DIM_V	This view stores information on RouteRule objects, which are used to route packets based on destination IP to a particular network entity.
VCN_SECURITY_LIST_DIM_V	This view stores information on a set of virtual firewall rules for your VCN.
VCN_SUBNET_DIM_V	This view stores information on a logical subdivision of VCN.
VCN_VLAN_DIM_V	This view stores information on virtual LANs (VLANs) which are broadcast domains that are created by partitioning and isolating a network at the data link layer.
VCN_VNIC_DIM_V	This view stores information on virutal network interface cards (VNICs), which reside in a subnet in a VCN.
VCN_VTAP_DIM_V	This view stores information on virtual test access points (VTAPs), which provide a way to mirror all traffic from a chosen source to a selected target.
VCN_FACT_V	Fact view for VCN. Measures include counts of various other networking components.
VCN_SUBNET_FACT_V	Fact view for subnet. Measures include IP, VNIC, and CIDR block counts.
VCN_VNIC_FACT_V	Fact view for VNIC. Measures include public and private IP counts.
VCN_EGRESS_INGRESS_SECURITY_RULES_DIM_V	This view stores information on the rules for allowing outbound and inbound IP packets.

The suffixes in the view names specify the view type:

FACT_V: Fact
DIM_V: Dimension

Relationship Diagram

This section provides diagrams that define the logical relationship of a fact table with different dimension tables.

The contents of each view and their relationships are listed in the following file: networking views.

These diagrams show the relationship of the networking fact views with different dimension views

VCN_FACT_V

VCN_SUBNET_FACT_V

VCN_VNIC_FACT_V

Relationship diagram showing the fact table, VCN_SUBNET_FACT_V connected to five dimension tables, COMPARTMENT_DIM_V, VCN_VNIC_DIM_V, VCN_VLAN_DIM_V, VCN_SUBNET_DIM_V, and VCN_DIM_V.

Relationships exist among dimensions. Dimensions can be joined directly to each other. These diagrams show the relationship between dimension views.

VCN_CAPTURE_FILTER_DIM_V

VCN_DHCP_OPTIONS_DIM_V

VCN_INTERNET_GATEWAY_DIM_V

VCN_IPV6_DIM_V

VCN_LOCAL_PEERING_GATEWAY_DIM_V

VCN_NETWORK_SECURITY_GROUP_DIM_V

VCN_PRIVATE_IP_DIM_V

VCN_PUBLIC_IP_DIM_V

Relationship diagram showing the dimension table, VCN_NETWORK_SECURITY_GROUP_DIM_V connected to one dimension table, COMPARTMENT_DIM_V.

VCN_ROUTE_TABLE_DIM_V

Relationship diagram showing the dimension table, VCN_IROUTE_TABLE_DIM_V connected to two dimension tables, COMPARTMENT_DIM_V and VCN_DIM_V.

VCN_SECURITY_LIST_DIM_V

VCN_VTAP_DIM_V

Relationship diagram showing the dimension table, VCN_INTERNET_GATEWAY_DIM_V connected to four dimension tables, COMPARTMENT_DIM_V, VCN_DIM_V, VCN_CAPTURE_FILTER_DIM_V, and VCN_SUBNET_DIM_V

VCN_EGRESS_INGRESS_SECURITY_RULES_DIM_V

Sample Queries

Sample queries for Networking.

List the tags associated with each subnet:

SELECT S.ID, T.TAG_TYPE, T.TAG_KEY_NAME, T.TAG_VALUE
FROM OCIRA.VCN_SUBNET_DIM_V S
LEFT JOIN OCIRA.TAGS_DIM_V T
ON S.ID = T.RESOURCE_ID;

Find security lists with CIDR 0.0.0.0/0:

SELECT ID AS SECURITY_LIST_OCID, DISPLAY_NAME AS SECURITY_LIST_DISPLAY_NAME, INGRESS_SECURITY_RULES, EGRESS_SECURITY_RULES
FROM OCIRA.VCN_SECURITY_LIST_DIM_V
WHERE (INGRESS_SECURITY_RULES LIKE '%"source":"0.0.0.0/0","sourceType":"CidrBlock"%')   
OR (EGRESS_SECURITY_RULES LIKE '%"destination":"0.0.0.0/0","destinationType":"CidrBlock"%');

Find subnets not following specific CIDR block rules:

SELECT ID AS SUBNET_ID, DISPLAY_NAME AS SUBNET_DISPLAY_NAME, CIDR_BLOCK, COMPARTMENT_ID, VCN_ID
FROM OCIRA.VCN_SUBNET_DIM_V
WHERE CIDR_BLOCK NOT IN ('10.0.0.0/24', '192.168.1.0/24');

Get the public and private IP count for each VCN:

SELECT VCN_ID, PUBLIC_IP_COUNT, PRIVATE_IP_COUNT
FROM OCIRA.VCN_FACT_V;

Data Lineage

The Customer Experience Semantic Model Lineage spreadsheet and Metric Calculation Logic spreadsheet for Networking provides an end-to-end data lineage summary report for physical and logical relationships in your data.

Subject Areas

This section provides information on the subject areas with data you maintain in Networking. These subject areas, with their corresponding data, are available for you to use when creating and editing analyses and reports. The information for each subject area includes:

Description of the subject area.
Business questions that can be answered by data in the subject area, with a link to more detailed information about each business question.
Job-specific groups and duty roles that can be used to secure access to the subject area, with a link to more detailed information about each job role and duty role.
Primary navigation to the work area that's represented by the subject area.
Time reporting considerations in using the subject area, such as whether the subject area reports historical data or only the current data. Historical reporting refers to reporting on historical transactional data in a subject area. With a few exceptions, all dimensional data are current as of the primary transaction dates or system date.
The lowest grain of transactional data in a subject area. The lowest transactional data grain decides how data are joined in a report.
Special considerations, tips, and things to look out for in using the subject area to create analyses and reports.

The subject areas are:
