Embodiments provide unique identification of telemetry reports generated by components of an IHS (Information Handling System) that supports a plurality of metric data sources. A source of metric data is detected, where the source may be a fixed or replaceable IHS component. The metric source is identified within a device descriptor table maintained by a remote access controller of the IHS. Based on a unique user-friendly label that is associated with the metric data source in the device descriptor table, the metric source is configured to generate metric reports. The generated metric reports are received and the label provided by the metric source is used to store data from the metric reports in a database row using the label as a unique database key. The user-friendly label can be used to perform efficient database queries without using a separate database column for storing a user-friendly description of the metric source.

Unique identification of metric values in telemetry reports

Systems and methods utilize telemetry data to provide administrators with metric information related to a detected IHS (Information Handling System) event, such as an error condition, where the provided metric information is particularized to the context of the event. A remote access controller (RAC) of the IHS stores metric reports received from metric sources. The RAC receives an indication of the event that specifies a first IHS component as a source of the event and specifies a time associated with the event. The RAC identifies stored metric reports generated by the first component prior to the first time and identifies stored metric reports generated by components that are logically and/o physically related to the first component. The RAC generates an event report that includes the metric reports generated by the first component prior to the first time and the metric reports generated by components related to the first component.

Event-based generation of context-aware telemetry reports

A system for distributing firmware, comprising a group controller operating on a processor and configured to perform an algorithmic process of sending an update task with a download host to one of two or more group members. A group member operating on a processor and configured to perform an algorithmic process of receiving the update task with the download host and to request a payload file from the download host.

System and method for providing an intelligent ephemeral distributed service model for server group provisioning

An information handling system includes an endpoint device and a service processor. The endpoint device is configured to share a passphrase with the service processor via shared memory architecture transfer mechanism. The service processor is configured generate the sent hash of a message; encrypt the message, the sent hash, and the nonce value using the passphrase to form an encrypted message; and transmit the encrypted message to the endpoint device over a sideband interface. The storage controller is further configured to decrypt the encrypted message using the passphrase to obtain the message, the sent hash, and the nonce value; compare the nonce value to a counter to determine if the nonce value is an old nonce value; calculate an observed hash of the message; and accept the message when the nonce value is not an old nonce value and the observed hash matches the received hash.

Mechanism to secure side band communication between service processor and an end point

A host device access monitoring and reporting system includes a management system coupled to server devices through a network. Each server device includes a BIOS that generates and transmits pre-boot access event reports for pre-boot access events occurring prior to the completion of a boot process for that server device, and an operating system that generates and transmits post-boot access event reports for post-boot access events occurring subsequent to the completion of the boot process for that server device. A remote access controller in each server device receives pre-boot access event reports from the BIOS in that server device and, in response, publishes pre-boot access event notifications to the management system. The remote access controller in each server device also receives the post-boot access event reports from the operating system in that server device and, in response, publishes post-boot access event notifications to the management system.

Proactive host device access monitoring and reporting system

Embodiments provide methods and systems for detecting rogue endpoints on a device management bus. A communications controller configured as a bus owner initiates discovery of managed devices coupled to the bus and generate a unique identifier for each managed device. The communications controller transmits a bus configuration message to the managed devices, including the respective unique identifiers. The managed devices are configured as bus endpoints based on the bus configuration message. The managed devices also capture the bus address of the communications controller from the received bus configuration message. Messages received by a managed device are authenticated as originating from the communications controller if the messages include the unique identifier provided to that managed device. The messages may be further authenticated by comparing the bus address of the message sender against the captured bus address of the communications controller.

System and method for detecting rogue devices on a device management bus

Sideband device management bus messages are filtered using software operations in order to minimize dropped messages and to maintain the bus in an operable state. Redundant sideband device management buses are utilized in order to provide fail-over transmission of messages in scenarios where one of the buses becomes inoperable. Multi-packet messages are transmitted to managed devices via the sideband bus connections. If an inoperable state is detected in a sideband bus connection during transmission of a multi-packet message, the portion of the multi-packet message not received by the managed device is transmitted via a redundant sideband bus connection with the managed device. Software filtering of bus transactions utilizes a circular DMA buffer for storing all incoming transactions. Transactions of interest are copied to buffers associated with specific endpoints for processing.
