ACI Console
The ACI Console provides a searchable inventory list that shows relationships between items in the Cisco ACI environment. Where relevant, the inventory shows the most recent ACI health score.
  • To limit the list to a particular node in the hierarchy, double-click that node.
  • To return to a higher level of the hierarchy, click the breadcrumb links.
  • To filter the inventory by a health-score threshold, use the slider at the top of the pane. The inventory shows nodes with children with health scores equal to or lower than the threshold.
The ACI Console also provides relationship diagrams for various aspects of the ACI inventory. The diagrams show alert icons on items that exceed customizable thresholds. Use the diagrams to understand how particular problems with the ACI infrastructure affect your applications. The ACI Console includes diagrams for the following inventory item types:
  •  
    Application Profile Diagram
    Shows the relationships between endpoint groups (EPGs) that support the application profiles (APs). Provider EPGs are connected to contracts connected to consumer EPGs. The diagram also shows the underlying leafs that support the endpoints in the EPGs.
  •  
    EPG Diagram
    Shows the AP parent and each end point. For each endpoint, the diagram shows the associated leaf.
  •  
    Endpoint Diagram
    Shows the EPG parent. If the endpoint is a vLAN, the diagram shows the connection to the leaf. If the endpoint is an application, the diagram shows the full supporting technology stack.
  •  
    Leaf Diagram
    Shows application profiles that contain endpoints which are connected to the leaf.
  •  
    APIC Diagram
    Shows leafs that are connected to the APIC controller.
     Because each spine is connected to each leaf and has no other relationships, the ACI console does not include a diagram for spines.
All diagrams share common functionality:
  • To open a diagram, click an item in the inventory.
  • To show more details for an item in the relationship map, hover over the icon for the item.
  • To show which thresholds are exceeded, hover over the alert icon in the relationship map.
  • To open the relationship map for another item, click the icon for an item in the current relationship map. The previous relationship map becomes a breadcrumb link on the right side of the diagram.
  • To open the context page for an item, click the item name in the relationship map.
  • To go to the ACI Health dashboard or the Switches Overview dashboard, click links in the upper left corner of the dashboard.
ACI Console Thresholds
To configure the thresholds for the alert icons, click the 
View Settings
 (gear) icon, and click 
Edit
. Assign Critical (red), Major (orange), and Minor (yellow) threshold for the following metrics:
  • CPU utilization
  • Health score
  • Interface utilization
  • Memory utilization

ACI Health Dashboard
The ACI Health dashboard provides focused information about your Cisco ACI environment. To highlight problem areas, the dashboard focuses on health scores and faults. To narrow the area of troubleshooting, change the context of the dashboard:
  • To find problematic switches, scope to the fabric.
  • To find a problem in a tenant, scope to a tenant.
  • To find a problem in an application, scope to an AP.
This dashboard shows the following information:
  • Counts of items in the Cisco ACI environment
  • Count of critical faults
  • ACI health scores for items in the environment
  • Aggregated fault trends by severity
  • AP and EPG inventory
Switches Overview Dashboard
The Switches Overview dashboard provides information about the status of switches. If you select the appropriate group of Nexus 9000 switches, you can monitor the infrastructure behind an ACI environment. For example, you can analyze critical faults, CPU, memory, and interface utilization for these switches.
 Most metrics on this dashboard require SNMP data collection from the Nexus 9000 switches through 
CA Performance Management
.
This dashboard shows the following information:
  • Switches with the highest CPU and memory utilization
  • Switches with the highest interface utilization
  • Switches with the highest policy CAM utilization
  • Switches with the most critical faults
ACI Workflows
The ACI dashboards are designed with the following role-based workflows:
  • An
     ACI System Administrator
     is responsible for maintaining the Cisco ACI environment.
    1. Use the ACI Console to look at the fabric and VMs:
      • View the relationship of the fabric to APs and EPGs.
      • View the relationship of fabric nodes to compute resources.
      • View the relationship of VMs to APs and EPGs.
      • View the relationship of VMs to fabric nodes and compute resources.
    2. Use the ACI inventor to track the number of entities in the ACI environment.
    3. Track the performance of APs and EPGs on context pages.
  • Tenant Administrator
     is responsible for managing tenants in the ACI environment.
    1. Scope the ACI Console to the tenant, and look at VM relationships to APs, EPGs, compute resources, and the fabric.
    2. Use the ACI Health dashboard to look at the health score and faults within the tenant.
    3. Track the performance of APs and EPGs on context pages.
  • An 
    Application Owner
     is responsible for a single application that is hosted in the ACI environment.
    1. Scope the ACI Console to the AP, and look at VM relationships to the AP, EPGs, compute resources, and the fabric.
    2. Use the AP context page to monitor computer and storage utilization by VM and in aggregate and top VM utilization.
  • Fabric Administrator
     is responsible for maintaining the health of the network in the ACI environment.
    1. Scope the ACI Console to the fabric, and look at fabric relationships to APs and EPGs and the relationships of fabric nodes to compute resources.
    2. Use the ACI Health dashboard to look at the health score and faults within the fabric.
    3. Track the performance of the Nexus 9000 switches on the Switches Overview dashboard and the context pages for the switches.
