Viewing Telemetry KPI Alarms for Fabric Devices and Ports

In Contrail Networking Release 2011, the Fabrics page displays additional detail about the health of your devices and interfaces, gathering data from telemetry metrics and profiles configured on these devices. These pages will show if any key performance indicators (KPIs) have crossed a threshold value. You can also configure metrics and assign telemetry profiles from the Fabrics Overview page. See Figure 10.

Fabric Devices

To view fabric devices:

Navigate to Infrastructure > Fabrics.

The Fabrics page displays. An error icon displays next to the fabrics name if there are critical or major alarms present.

Figure 1: Infrastructure > Fabrics

Table 1: Fabrics Page Information
Column	Description
Name	Name of the fabric. Note: A red alert icon displays next to the fabric name if there are any active critical or major alarms.
Physical Devices	Number of connected physical devices.
Ports	Number of physical ports.
Ports Down	Number of physical ports nonfunctional.
Critical/Major Alarm	Number of critical alarms reported by the telemetry profiles.
Spine	Number of spine devices connected in the fabric.
Leaf	Number of leaf devices connected in the fabric.
Overlay ASN	Autonomous system number for the EVPN overlay.

Select the <Fabric Name> to view more details about devices, ports, and alarms.

The Fabric Devices page displays an overview of the fabric devices and their real-time status.

Figure 2: Fabric Devices Page

Table 2: Fabric Devices Page Information
Column	Description
Alarms Count	A progress bar chart of critical, error, or warning alarms. Click Critical, Error, or Warning to display only alarms with that severity level.
Ports Count	A pie chart of connected ports showing up or down operational status and administrative status for physical ports.
Name	Name of the fabric device. Click a `<device name>` to navigate to the device’s detailed overview page.
Interfaces	Number of connected physical interfaces for that device.
Interfaces Down	Number of physical interfaces nonfunctional for that device.
Operational Status	Device status as Up, Down or At Risk/Changed. This status is based on the telemetry profiles.
Administrative Status	Device status as Active, Inactive, or Changed. This status applies to the Contrail Networking configuration component versus telemetry profiles.
Management IP	IP address used as the management IP address. Contrail Command uses this IP address to connect to the Contrail Insights Flows node.
Loopback IP	Loopback subnets are used to auto-assign loopback IP addresses to the fabric devices.
Model	Brand and device type.
Physical Role	Device roles define the routing and bridging responsibilities for each device in a fabric. A fabric device can have one physical role and one or more routing bridging roles. Use this page to assign roles to each device in the fabric. See the “Device Roles” section of the Contrail Enterprise Multicloud for Fabric Management guide for information on device roles.
Overlay Role	Routing-bridging role, such as CRBGateway, ERBGateway, and so on.
Namespaces	Refers to the objects, such as BGP ASN pool, Management Subnet, or peer-to-peer (P2P) interface subnet that is assigned to a fabric.
Intent	High level abstract operations that user refers to in terms of the application-to-application connectivity he is looking for. For example VN, logical router, physical network function (PNF), and so on.
Device Credentials	Credentials for accessing fabric devices.

Ports

Click the Ports tab to view details about ports.

Figure 3: Fabrics Ports Page Information

The Ports tab displays the following information:

Table 3: Fabrics Ports Page Information
Column	Description
Device	Device name
Ports	Number of ports reported by telemetry profiles.
Operational Status	Device status as Up, Down or At risk/Changed. This is based on information received from the telemetry profiles.
Administrative Status	Device status as Active, Inactive, or Changed. This status applies to the Contrail Networking configuration component versus telemetry profiles.

Alarms

Click the Alarms tab to view all alarms on the fabric.

Figure 4: Fabrics Alarm Page

The Alarms tab displays the following information:

Table 4: Fabrics Alarm Page Information
Column	Description
Device	Device Name
Severity	Alarm severity. Ranging from none to critical. Corresponds with Alarms Count at top of page.
Name	Alarm name.
Description	Brief description of alarm, that is pulled from telemetry profiles.

Alarms Count, Ports Count, and Device Overview

In Alarms Count, click Critical, Error, or Warning to display only alarms with that severity level.

Figure 7: Select Filter Values in Fabric Alarms

Note:

The same behavior applies to the legend items next to the Ports Count pie chart.

The Device Overview page shows more detail provided by the telemetry profiles. The Alarms panel displays up to eight alarms. Click View all critical alarms for this device to see any additional alarms.

Figure 8: Fabric Device Overview Page

This returns you to the Fabric page and displays device and severity dependent on your choices. Click Open filters and select Reset to return the page to displaying all devices and alarms. See

In Ports Count, you can click a port name to see more detail. This launches the Port Overview page. Overview charts are drawn specifically for the port that you are viewing. To return to full view of all ports, click the Open filters icon and select Reset.

Configure and Assign Telemetry Profiles from Fabric Overview

When there are no telemetry metrics configured and assigned to applicable fabric devices, you can accomplish this from the Fabric Overview page. For more information about telemetry profiles, see Contrail Insights Flows in Contrail Command.
