About Cisco Success Network
Cisco Success Network is user-enabled cloud service that establishes a secured connection with the Security Service Exchange (SSE) cloud to stream ASA usage information and statistics. Streaming telemetry provides a mechanism to transmit ASA usage and other details in structured format (JSON) to remote management stations for the following benefits:
To inform you of extra technical support services and monitoring that are available for your product.
To help Cisco improve its products.
By default, the Cisco Success Network is enabled on the Firepower 9300/4100 platforms that hosts ASA devices (at the blade level). However, for the telemetry data to be transmitted, you must enable the configuration on FXOS at chassis level (see Cisco Firepower 4100/9300 FXOS CLI Configuration Guide) or enable the Cisco Success Network on the chassis manager (see Cisco Firepower 4100/9300 FXOS Firepower Chassis Manager Configuration Guide) ASA allows you to disable the telemetry service at any point in time.
The telemetry data that is collected on your ASA devices includes CPU, memory, disk, bandwidth, and license usage, configured feature list, cluster/failover information, and the alike. Refer Cisco Success Network - Telemetry Data.
Supported Platforms and Required Configurations
Supported on FP9300/4100 platforms with ASA version 9.13.1 or above running on it.
Requires FXOS version 2.7.1 or above to connect with the cloud.
The SSE connector on FXOS must be connected to the SSE cloud. This connection is established by enabling and registering the smart license with smart licensing backend. The SSE connector on FXOS is automatically registered to the SSE cloud by registering smart license.
The Cisco Success Network configuration must be enabled on chassis manager.
The telemetry configuration must be enabled on ASA.
How Does ASA Telemetry Data Reach the SSE Cloud
Cisco Success Network is supported on Firepower 9300/4100 platforms in ASA 9.13(1) by default. The FXOS service manager sends telemetry request daily to the ASA application running on the Firepower platform. The ASA engine, based on the configuration and connectivity status, sends the telemetry data either in standalone mode or cluster mode to FXOS. That is, if the telemetry support is enabled in ASA and SSE connector status is connected, the telemetry thread pulls the needed information from various sources such as system or platform or device APIs, license APIs, CPU APIs, memory APIs, disk APIs, smart call home feature APIs, and so on. However, if the telemetry support is disabled in ASA or the SSE connector status is disconnected, ASA sends a response to FXOS (appAgent) indicating the telemetry configuration status and does not send any telemetry data.
FXOS has only one SSE connector instance running on it. When it gets registered with the SSE cloud, it is considered as one device and SSE infra assigns FXOS with one device ID. Any telemetry report that is sent through the SSE connector is categorized under the same device ID. Therefore, FXOS aggregates the telemetry report from each ASA into a single report. Other contents such as smart license account information are added to the report. FXOS then sends the final report to the SSE cloud. The telemetry data is saved in the SSE data exchange (DEX) and available for the Cisco IT team to use.
