Cisco ACI monitoring
Cisco Application Centric Infrastructure (ACI) is a software-defined networking (SDN) solution that provides complete visibility over your physical and virtual network components. It is primarily used to streamline data center operations. Site24x7 allows you to monitor your Cisco ACI networks through REST APIs and obtain complete visibility into your Application Policy Infrastructure Controller (APIC), fabric, tenants, and endpoint groups.
Common terms
- Cisco APIC: The main architectural component that is the unified point of automation and management for the Cisco ACI fabric.
- Fabric: Comprises discrete components that are connected in a spine and leaf topology, managed as a single entity.
- Spine: Spine switches act as the backbone of the ACI fabric and help connect all the leaf nodes.
- Leaf: Access switches that aggregate traffic from servers and connect to the spine.
- Tenants: Within the ACI fabric, a tenant provides logical segmentation to isolate different sets of resources, such as networking, computing, and storage, while sharing the same physical infrastructure.
- Endpoint Groups: An endpoint is a single network device connected to the network directly or indirectly. An Endpoint Group (EPG) represents a group of endpoints, such as virtual machines, servers, or applications, that share common policy requirements.
Prerequisites
- An On-Premise Poller (version 5.6 and above) must be installed on the device from which the Cisco ACI network will be monitored.
- The On-Premise Poller and the Network Module must be up and running.
- Correct credentials must be provided for connecting to the Cisco ACI network.
NoteCredentials and customer details are encrypted before being stored in Site24x7.
Use case
Imagine an organization trying to change the way it deploys and manages applications across its data center infrastructure. The challenges it would run into would be tedious manual configurations, network silos, and a lack of visibility into performance.
Cisco ACI uses a policy-based approach to automate and simplify network provisioning and management. It enables administrators to define policies that specify how applications should communicate and be managed in the network rather than dealing with individual network device configurations.
How it works
When you add a device to Site24x7, it connects to your Cisco ACI network using the credentials you provide. It then fetches data using the API for each monitor you add and displays it. Data is displayed at three levels for the fabric: Super Spine, Spine, and Leaf. You can also view details according to Tenants and Endpoint Groups.
Adding a Cisco ACI monitor
To begin monitoring, add your Cisco ACI networks to Site24x7.
Viewing the monitor summary
- Log in to your Site24x7 account.
- Navigate to Network > Cisco ACI Monitors.
- Click the required Cisco ACI monitor. The Summary page will open.

Fabric
View details about the Leaf, Spine, and Super Spine in the Fabric tab. Click the pencil icon beside each row to set the threshold for that entity (Figure 3, marked in blue) or click the Threshold Configuration button on the top-right of each section (Figure 3, marked in purple) to edit thresholds in bulk.

Tenants
View all the tenants in the Tenants tab. Click the pencil icon beside each row to set the threshold for that entity (Figure 6, marked in blue) or click the Threshold Configuration button on the top-right of each section (Figure 6, marked in purple) to edit thresholds in bulk. You can also click on the name of each tenant to view more insights about each tenant (Figure 7).
