Abstract: Embodiments disclosed herein relate to a method, system, and computer-readable medium for monitoring an application executing across a plurality of containers. A performance monitor requests a list of containers created on at least one computing system. The performance monitor retrieves information associated with a creation of each container in the list. The performance monitor parses the information associated with each container in the list to identify a cluster of related containers that are running the applications. The performance monitor displays a topology that relates the containers of the cluster to resources in the at least one computing system. The performance monitor identified a pair of containers that are negatively correlated based on the topology. The performance monitor adjusts the application to remove the negative correlation between the pair of containers.

Abstract: This disclosure describes how data supporting real-time reporting services can be cached during a log intake process. In particular, instead of caching all the log data being generated by an operational system, only the log data relevant to existing queries associated with the real-time reporting services are cached. In some embodiments, only particular metrics contained within the log data are stored for rapid access by the real-time reporting services.

Abstract: The current document is directed to methods and systems that efficiently cache log/event messages in log/event-message systems incorporated within distributed computer facilities. The log/event-message systems provide the data-collection, data-storage, and data-querying functionalities that provide a basis for distributed log-analytics systems which, in turn, provide a basis for automated and semi-automated system-administration-and-management systems. Efficient caching significantly extends the period of time that networking failures and log/event-message processing delays can be tolerated by log/event-message systems without significant loss of information. Rather than caching individual log/event messages, message collectors that employ the currently disclosed technologies cache information regarding log/event-message types, leading to efficient compression of the cached information. As a result, message collectors can cache log/event messages without significant loss of information for time periods of several orders of magnitude greater than those achieved by caching individual log/event messages.

Abstract: A system and method for sampling application programming interface (API) execution traces in a computer system uses feature vectors of the API execution traces that are generated using trace-context information. The feature vectors are then used to group the API execution traces into clusters. For the cluster, sampling rates are generated so that a sampling rate is assigned to each of the clusters. The sampling rates are then applied to the API execution traces to adaptively sample the API execution traces based on the clusters to which the API execution traces belong.

Abstract: Automated methods and systems for generating Grok expressions for extraction of metric data from any type of log message are described. Method and systems include construction of a directed graph from Grok patterns. A sample log message is selected from log messages that record metrics values of a desired metric. The directed graph is used to construct a Grok expression from the sample log message. The Grok expression is then used to parse log messages that are of the same type or format as the sample log message to extract the desired metric data from the log messages. The metric may in turn be used to troubleshoot problems anchor identifying potential root causes of problems in a data center or other type of distributed computing system.

Abstract: System and computer-implemented method for managing workloads in a computing environment use collected resource utilization metrics for a workload of a compute instance running in the computing environment that are superimposed to produce a unified time series of the resource utilization metrics for the workload. Undesired periodic patterns are then removed from the unified time series of the resource utilization metrics, which is used to identify the compute instance as a particular type of compute instances. Based on the identification, an action is recommended and implemented on the compute instance.

Abstract: Methods and systems described herein are directed to aggregating and querying log messages. Methods and systems determine event types of log message generated by event sources of the distributed computing system. The event types are aggregated into aggregated records for a shortest time unit and event types are aggregated into aggregated records for longer time units based on the aggregated records associated with the shortest time unit. In response to a query regarding occurrences of an event type in a query time interval, the query time interval is split into subintervals with time lengths that range from the shortest time unit to a longest time unit that lie within the query time interval. The method determines a total event count of occurrences of the event type in the query time interval based on the aggregated records with time stamps in the subintervals. The event count in the query time interval may be used to detect abnormal behavior of the event sources.
