  • Publication number: 20220374439
    Abstract: A log sampling and storage system reduces volumes of stored log information. A log storage engine receives a series of log messages responsive to a request. The engine compares that series to various patterns previously generated from historical log data. This comparison can reference •a name of the request; •a total time to process the request; •an item count; •a message length; and/or •a message hash code. Comparing incoming log series with the predefined patterns, results in generation of a similarity score. If the score falls outside a tolerance, the existence of an outlier log message series is indicated, and that outlier log message series is stored in its entirety. However, if the similarity score falls within a tolerance, similarity to an existing predefined pattern is indicated. Rather than storing the (non-outlier) log message series, the engine directs storing a link to a sample log message series reflecting the pattern.

  • Patent number: 11409570
    Abstract: System computing resources are dynamically managed by a resource management layer together with resource server pool. A group monitor collects data of server operation (e.g., CPU usage, memory consumption, queue size) in a particular group (e.g., customer-facing servers, job servers). The group monitor: calculates a weighted score for each server, sorts the scores of each server, maintains a sequence of scores, and periodically reports the score list to a resource manager. When an incoming request is directed to a particular server group, the group monitor redirects the request to a lowest-scoring server, and recalculates/sorts the score list. The resource manager monitors and throttles the servers in each group. Where servers in a group are experiencing high workload, the manager adds to the group server(s) from the resource pool. Conversely, where server group members are experiencing a low workload, the manager removes the lowest scoring server(s) to the resource pool.

  • Patent number: 11334558
    Abstract: Techniques are described for managing the optimized refreshing of metadata associated with online and live systems. In some implementations, a set of metadata modules associated with one or more entities are identified, the metadata modules defining metadata associated with a particular data model for the associated entities. A request to initiate a refreshing of the metadata for a subset of the set of metadata modules is identified. Each metadata module from the subset of the set of metadata modules is prioritized into a prioritization order. A determination is made as to whether two or more idle database connections are available. In response to determining that two or more idle database connections are available, a concurrent refresh of the subset of the set of metadata modules is initialized in the prioritization order.

  • Patent number: 11239541
    Abstract: The invention provides a radar bracket with self-adaptiveness to a curved surface. The radar bracket comprises: a bracket body provided with a radar mounting part; and, a bracket flanging configured to be fixed to a skin and being arranged at a periphery of the bracket body. The bracket flanging is provided with a plurality of weakened structures for providing its self-adaptiveness to a curved surface. When the radar bracket is to be bonded or welded to a skin, thanks to the bracket flanging's ability of easily deform to adapt to different curved surfaces, the same radar bracket can be attached to different positions of the skin with different curvatures. According to the invention, it is provided a radar bracket with self-adaptiveness to a curved surface that can be used universally all over an assembled automobile, hence the production costs, the mounting costs, and the probability of erroneous mounting are greatly reduced.

  • Patent number: 11153374
    Abstract: A cloud computing system receives a plurality of requests originating from a plurality of tenants. Thereafter, a load balancer forming part of the cloud computing system dispatches each request to one of a plurality of groups of servers based on a group mapping table configured to optimize a cache hit ratio. Each group of servers includes a plurality of servers dispatching each request to one of the plurality of servers within each group of servers. The cloud computing system provides responses to the requests to the respective tenants as generated by the respective servers within the respective groups of servers. The group mapping table can be generated by monitoring historical request statistics for each of the tenants, monitoring current resource consumption by the plurality of groups of servers when handling requests from the tenants, and associating each tenant with one of the groups of servers based on such monitoring.

  • Publication number: 20210173838
    Abstract: Disclosed herein are system, method, and computer program product embodiments for processing a data query from a user device. In an embodiment, a data storage operator receives the data query from the user device. The data storage operator determines that the data query is a snapshot query and the snapshot query does not have a skiptoken. The data storage operator then determines that the snapshot query satisfies snapshot conditions and takes a snapshot based on the snapshot query. The data storage operator stores the snapshot into the snapshot storage and extracts data from a data storage based on the snapshot. The disclosed system enables an intelligent data query by determining whether or not to perform snapshot query. When performing snapshot query, the snapshot is stored in the snapshot storage for future use. In such a case, the data query is efficient and accurate.

  • Publication number: 20210080538
    Abstract: A flexible radar support for absorbing vibration deviation comprises a support base and a support top cover that are engaged with each other in an interlocking manner. A housing space for arranging a radar is formed between the support base and the support top cover. The support base includes: a centrally arranged base center, and a base edge circumferentially arranged around the base center. The base edge and the base center are connected through four flexible structures that form U-shaped cantilever beams protruding towards the support top cover. With the flexible radar support provided, and with the design of U-shaped flexible structures, where an automobile body vibrates at a large amplitude, the flexible radar support can still absorb swaying in the up and down, and left and right directions during the course of driving, thereby reducing the impact of the automobile body's vibrations on the detection precision of a radar.
