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 classify, on a cloud server, a plurality of clusters of an edge network based on one or more classification parameters, detect that a first cluster in a first datacenter of the edge network has an issue, determine a classification parameter value of the first cluster, determine that a second cluster in a second datacenter of the edge network has a second classification parameter value within a predetermined amount of the classification parameter value, and send an instruction to the second cluster to perform a remediation action.

Recommendation engine based on classification of virtualized workload

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 a stored configuration state of a cluster, receive a snapshot of the configuration state of the cluster, determine that an entity of the cluster is different between the stored configuration state and the snapshot, determine that a first timestamp of the stored configuration state is less than a second timestamp of the snapshot, and send an indication that the entity is changed.

Reconciliation of the edge state in a telemetry platform

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 detect, on a server, a first symptom observable on a first one or more clusters. In some embodiments, the first symptom is indicative of an issue. In some embodiments, the instructions cause the processor to trigger additional data collection by a plurality of edge processing units for the first one or more of clusters, detect, in a second one or more clusters within the first one or more clusters, a second symptom indicative of the issue, and generate a remediation action for a third one or more clusters having the first symptom and the second symptom. In some embodiments, the second one or more clusters include the third one or more clusters.

Smart collection and processing in telemetry system

A data management device includes a cache for a data storage device and a processor. The cache includes cache devices that store a block set. The processor obtains a cache modification request that specifies a first block of the block set, updates a copy of a header of the block set in each of the cache devices based on the modification request, updates a copy of meta-data of the block set in each of the cache devices based on the cache modification request, and updates the first block in a first cache device of the cache devices based on the cache modification request.

Metadata protected sparse block set for SSD cache space management

A system and method include determining, by a telemetry control system of a telemetry system that an agent associated with the telemetry control system terminated during operation. The agent collects telemetry data from data sources associated with the telemetry system. The system and method also include determining that a number of times the agent has terminated is greater than a predetermined threshold, restarting the agent after a first predetermined delay in response to exceeding the predetermined threshold, and determining that the agent terminated again within a predetermined time period upon restarting. The system and method further include updating a configuration file of the agent in response to the termination within the predetermined time period and restarting the agent with the updated configuration file. The updating is based upon an agent termination record of the agent.

System and method for managing telemetry data and agents in a telemetry system

A method for upgrading a file system in a data storage environment is provided. A storage system identifies a set of boundaries of one or more sets of hard disks based on a first block management data structure (BMDS), where the first BMDS includes information describing a storage volume representing the one or more sets of hard disks. For each identified boundary, the storage system identifies a data block range of a set of data blocks, where the data block range includes metadata of one set of hard disks that is stored on the set of data blocks. Further, the storage system concurrently generates a plurality of second BMDSs, each of the second BMDS corresponding to one of the sets of hard disks, including simultaneously retrieving metadata of the sets of hard disks, where the second BMDSs are constructed based on the retrieved metadata, representing an upgraded file system.

Method for parallel file system upgrade in virtual storage environment

A method, article of manufacture, and apparatus for scaling an index on a solid state drive in a deduplicated storage system is discussed. The index may be scaled as index hash buckets approach capacity, or as new solid state drives are added to the system. The hash buckets may be mapped to HDD hash buckets, which are stored on a hard drive.
