Abstract: Methods and materials for modulating low-nitrogen tolerance levels in plants are disclosed. For example, nucleic acids encoding low nitrogen tolerance-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased[RCL2] low-nitrogen tolerance levels and plant products produced from plants having increased low-nitrogen tolerance levels.

Abstract: Methods and systems described herein automate various aspects of troubleshooting a problem in a distributed computing system for various forms of object information regarding objects of the distributed computing system. In one aspect, the object information includes metrics, log messages, properties, network flows, events, and application traces. Methods and systems learn interesting patterns contained in the object information. The interesting patterns include change points in metrics and network flows, changes in the types of log messages, broken correlations between events, anomalous event transactions, atypical histogram distributions of metrics, and atypical histogram distributions of span durations in application traces. The interesting patterns are displayed in a graphical user interface (“GUI”) that enables a user to assign a label identifying a problem associated with the interesting patterns.

Abstract: Methods and systems are directed to finding various types of evidence of performance problems with objects in a data center, troubleshooting the performance problems, and generating recommendations for correcting the performance problems. A performance problem with an object of a data center, such as a server computer, an application, or a virtual machine (“VM”), may result from performance problems associated with other objects of the data center. The methods and systems detect origins of performance problems with objects for which no alerts and parameters for detecting the performance problems have been defined or detect performance problems related to alerts that fail to point to a root cause of the performance problem.
