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

Methods, apparatuses, and systems for real-time monitoring and automated intervention of a power generation. Embodiments may include receiving operating data from components of the power generation system. A potential failure condition for the components may be determined from real-time operating data of the received operating data before an occurrence of the potential failure condition. An alert may be issued in response to determining the real-time operating data indicates a potential failure condition, and instructions for remedying the potential failure condition may be transmitted to the power generation system. An algorithm for determining whether the real-time operating data indicates the potential failure condition may be updated by using preceding operating data in response to detecting the potential failure condition.

Real-time monitoring and automated intervention platform for long term operability of fuel cells

The disclosed embodiments provide a system for performing multi-tenancy distribution of a graph database cache. During operation, the system obtains a cache of a set of records in a graph database storing a graph, wherein the graph includes a set of nodes, a set of edges between pairs of nodes in the set of nodes, and a set of predicates. Next, the system identifies one or more records in the cache that fail a validation test. The system then merges a remainder of the cache with online updates to the subset of records to produce a merged version of the cache. Finally, the system distributes the merged version to one or more instances of the graph database for use in processing queries of the graph database.

Multi-tenant distribution of graph database caches

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

A fuel cell fleet has a plurality of fuel cell systems each connected to a data server. The data server may be configured to obtain operational data from of the plurality of fuel cell systems. An efficiency controller operably connected to the data server and is configured to predict an efficiency and a power output of the fleet from the operational data and optimize the efficiency of the fleet to minimize the fleet fuel consumption while maintaining a desired fleet output power. The efficiency may be determined by a ratio of the fleet output current or output power to the fleet fuel consumption.
