The disclosed embodiments provide a system for performing unified error monitoring, alerting, and debugging of distributed systems. During operation, the system receives logs of activity within a distributed system over event streams in a distributed streaming platform. Upon identifying an error in the received logs, the system collects, from the event streams, log entries generated within a time window of the error into a contextual log associated with the error. The system then outputs an alert containing metadata for accessing the contextual log.

Unified error monitoring, alerting, and debugging of distributed systems

A system, method, and apparatus are provided for visualizing quotas on resources within a computing environment (e.g., a data center, a computing cluster) that includes multiple brokers, gateway servers, or other entities that control access to the resource(s). Through a visualization interface, an operator of a quota system can set, change, and/or delete quotas on resources and/or sub-resources for any number of clients or consumers of the resources. The visualization interface may also enable access to a log of changes to quotas and/or graphs or other displays of statuses of any selected quotas for any selected clients and resources/sub-resources.

Visualization of computer resource quotas

A system, method, and apparatus are provided for identifying clients or consumers of one or more controlled resources within a computing environment (e.g., a data center, a computing cluster). The resources may be controlled via the enforcement of quotas, wherein different clients have different quotas for the controlled resource(s). A client associated with a given call to a resource is identified using a tuple formed from identifiers of multiple services in the call stack, such as a first service (e.g., a front-end or user-facing service) and an immediate service (e.g., a final service in the stack prior to receipt of the call at a gateway, broker, or other entity that manages access to the controlled resources).

Client identification for enforcing computer resource quotas

Some implementations provide a user interface for generating an electronic document. An external component may be launched within the user interface for accessing external data, and context data of the current document may be provided to the external component. The external data that corresponds to the context data for the document may be displayed within the user interface, such as for enabling a user to interact with the data and/or include a portion of the data in the document.

Implementation of opportunistic use of stations in a wireless network as repeaters is described. In one implementation, a station detects the existence of rate anomaly in a wireless network. In response to the rate anomaly, the station may transform into a software repeater for certain other neighboring stations. The repeater function allows for the relaying of packets sent by these neighboring stations to the access point and vice versa. The other neighboring stations, owing to their relative proximity to the repeater station, transmit data at a higher rate to the repeater station. Thus, the removal of the slower stations reduces clogging of the access point and increases the overall data rate within the wireless network. Further, a zero-overhead network coding protocol may be implemented in conjunction with the repeater function to increase capacity of the wireless network.

Opportunistic use of wireless network stations as repeaters

A method and an apparatus for securely mixing and splitting multiple audio data streams and determining the order of processing the audio streams. A audio server and an audio device driver are in kernel space of a given computer system. In one embodiment, the computer system has a data flow checker and adjuster for checking the flow of data into data queues and a setup application for connecting the audio server and the audio device driver. The data flow checker and adjuster adjusts the flow of data by sending a message up or downstream instructing the up or downstream processes/devices to send more data or stop sending data depending on how full the data queues are.
