Various embodiments disclosed herein are related to a non-transitory computer readable storage medium. In some embodiments, the medium includes instructions stored thereon that, when executed by a processor, cause the processor to determine, in a cluster of host machines, a priority level of telemetry data collected in the cluster, at least based on a data type of the telemetry data and a tag and store the telemetry data in a storage in the cluster. In some embodiments, a quality-of-service (QoS) is associated with the priority level. In some embodiments, the storage is associated with the priority level. In some embodiments, the medium includes the instructions stored thereon that, when executed by the processor, cause the processor to send the telemetry data from the storage to a server in accordance with the QoS, wherein the server is separate from the cluster.

System and method to provide priority based quality of service for telemetry data

Various embodiments disclosed herein are related to an apparatus. In some embodiments, the apparatus includes a processor and a memory. In some embodiments, the memory includes programmed instructions that, when executed by the processor, cause the apparatus to receive an indication that an entity state of an entity has been updated, and, in response to receiving the indication that the entity has been updated, determine that the number of updates of the entity within a time period exceeds a threshold. In some embodiments, the memory includes the programmed instructions that, when executed by the processor, cause the apparatus to determine that the time period has expired, and, in response to determining that the time period has expired, collect the entity state of the entity.

System and method for scalable telemetry

Various embodiments disclosed herein are related to an apparatus. In some embodiments, the apparatus includes a processor and a memory. In some embodiments, the memory includes instructions that, when executed by the processor, cause the apparatus to collect, at a cloud server, service data from a collector framework service of an edge network. In some embodiments, the memory includes instructions that, when executed by the processor, cause the apparatus to provide a configuration to the collector framework service based on the service data.

System and method for managing clusters in an edge network

Various embodiments disclosed herein are related to a non-transitory computer readable storage medium. In some embodiments, the medium includes instructions stored thereon that, when executed by a processor, cause the processor to receive, on a cloud server coupled to a cluster on an edge network, a configuration state of the cluster, map the configuration state to a list of streams, send, to the cluster, the list of streams, and receive an indication that the cluster subscribed to the list of streams.

Caching metadata that identify hot blocks at a per local cache level are tracked. Tracked caching metadata are maintained so as to be persistent and shared across nodes of the cluster. Local caches are pre-warmed by using maintained caching metadata, responsive to detecting specific node level events. Such events can result in hot blocks being absent from a local cache, such as a failover between nodes or an unexpected failure local to a specific node. Another event example is the access of shared storage content, such as opening a file or mounting a file system by a specific node, in response to which the associated local cache can be pre-warmed using the tracked caching metadata for the specific file, or for each file of the file system. To pre-warm a local cache, hot blocks of stored content identified by corresponding caching metadata are loaded into the local cache.

Local cache pre-warming

A computer-implemented method for eliminating inconsistencies between backing stores and caches may include (1) detecting at least one inconsistency between a backing store and a cache, (2) identifying a synchronization marker that bifurcates write operations queued in the cache into (i) a subset of one or more write operations known to have been successfully performed on the backing store and (ii) an additional subset of one or more additional write operations not yet known to have been successfully performed on the backing store, (3) identifying the additional subset of additional write operations based at least in part on the synchronization marker, (4) performing the additional subset of additional write operations on the backing store, and then (5) updating the synchronization marker based at least in part on performing the additional subset of additional write operations on the backing store. Various other methods, systems, and computer-readable media are also disclosed.

Reservation conflicts are resolved in a clustering and storage system with SCSI-3 PR fencing enabled. For each specific node, all paths to shared storage are registered with a unique key. Only registered nodes can access the shared storage, and only one reservation can exist amidst multiple registrations. A command failure with a reservation conflict resulting from an attempt to access the shared storage is detected. In response, it is determined whether the specific node is registered with its unique key. If so, it is determined that the node is not fenced off from the shared storage, and the reservation conflict is to be resolved. To do so, the node is re-registered for all paths to the shared storage with the node's unique key. The failed command is then re-started. If the node is not registered, it is determined that the node is fenced off.
