Call Home data transmission
The AutoSupport Client Agent transmits data on a routine basis to provide proactive monitoring and advanced diagnostics for support purposes. These data collections and transmissions are classified into 4 primary categories:
Event data
Configuration and Inventory data
Telemetry and Performance data
Diagnostic data
The following section describes each category, their transmission interval, and basic properties:
Interval:
Immediately upon an event detection, such as a hardware or software fault or failure
Basic properties:
Appliance mode (primary or media server)
Appliance state (healthy or not healthy)
Serial number
Time of failure
Firmware versions
Extended attributes of only the failed components:
Battery voltage level, charge state, etc.
Interval:
Once per 24 hours
Basic properties:
Inventory of all hardware components including:
Manufacturer
Model
Serial Number
Type
Location
Firmware
Other component-specific metadata or attributes provided by the component vendor
Configuration data including user-defined configuration states:
Storage configuration
Network information
Feature enable/disable flags
Telemetry and performance data:
Storage utilization
Extended attributes of certain components, for example, battery voltage, charge state, thermal sensor data, fan speeds, and power supply voltages.
Interval:
Every three days
If a failure state is detected during this time the DataCollect package is assembled within 30 minutes. The three-day transmission cadence resets.
