Fabric Health



Note: Selecting Dashboards → Fabric Health displays information about a Fabric assuming a fabric was created and added. For more information about creating and adding a Fabric please refer to the ZTP - Zero Touch Provisioning section in this manual.



Selecting Dashboards → Fabric Health → displays important information about the Fabric and/or individual switches within the Fabric.


UNUM provides access to specific feature help documentation via the Help Button  icon.


Select the desired Fabric from the left side navigation bar and the dashboard updates showing all Switch entries from all switches within the Fabric.


The dashboard displays:


  • Top 10 Switches by Memory Utilization (%)
  • Top 10 Switches by CPU Utilization (%)
  • Alarms
  • Global Fabric Resources
  • Top 5 Interfaces by Link Bandwidth Utilization (%)
  • Top 5 Interfaces by Total Errors and Congestion Drops
  • Top 10 Switches by vFlow Hardware Table Utilization
  • Top 10 Switches by MAC Hardware Table Utilization
  • Top 10 Switches by IPv4 Routes Hardware Table Utilization
  • Top 10 Switches by Host Routes Hardware Table Utilization


for the entire Fabric.


Additional parameters include: Input and Output by port number, Alarm by type along with visual indicators providing critical information about switch load, interface traffic and interface errors in Red, Yellow or Green. Inner ring colors identify the specific switch while the outer ring depicts the load utilization by Red, Yellow or Green.

UNUM Platform Global - Dashboard Fabric Node Details


Each display in the dashboard includes a blue information button .  Rolling over this button provides the polling time interval for the widget.



UNUM Platform Global - Dashboard Info Time Interval

Rolling over sections of the pie charts reveal information by Switch name about Memory and CPU usage: cpu-idle, cpu-user and cpu-sys, as well as a Date and Time stamp.

While rolling over the Top Switches by Memory Utilization widget or the Top Switches by CPU Utilization widget and double clicking, the Switch Analytics / System Stats CPU/Memory dashboard launches. Using the browser back button returns you to the Fabric Health dashboard highlighting the previously selected switch.



Switch Analytics CPU / Memory Switch Dashboard


Rolling over other sections of the dashboard such as Top 5 Interfaces by Link Bandwidth Utilization (%) reveals information by Switch name about Port and Port Speed along with octets and octets percentage as well as a Date and Time stamp as illustrated in the following example:

The UNUM Fabric Health dashboard provides direct links to Fabric Management data and settings by rolling over and clicking on data points in the dashboard.  

For example, clicking in the Alarms section on a data point takes you to the Syslog dashboard and automatically applies a filter for the data point selected.

UNUM Platform Global - Fabric Health Alarms Syslog Dashboard

Clicking on data points and graphics within the Global Fabric Resources section reveals dashboard information about Active Endpoints, VLANs, VRF, VNI and VXLAN Tunnels and automatically applies a filter for the data point selected as illustrated in the following examples:

Note: In certain cases, the VLAN widget is empty and displays "No results found".   In some fabrics, all of end-points can be mapped to VXLANs.  Since the VLAN can be different on both sides of a VXLAN tunnel, the VLAN information is not carried in the vPort entry.

In a similar way to clicking on data points and graphics within the Global Fabric Resources section, Hardware widgets reveal switch-specific dashboard information by Leaf or Spine about vFlows, Forwarding Tables and Host Routes. 

Clicking on the individual bars in the histograms launches the respective dashboard as illustrated in the following example:
