摘要:
A workload scheduler detects a long-running job when its duration exceeds a threshold value calculated by applying a multiplication factor to an estimated duration of the job. An operator inputs two extreme values of the multiplication factor, which consist of an upper level for the short-duration jobs and a lower level for the long-duration jobs. An algorithm then calculates the appropriate multiplication factor for any particular job, giving much more weight to the upper level when the estimated duration is small, but which gradually swings the levels to give more importance to the lower level when the estimated duration is long.
摘要:
A monitor for information technology resources improved by introducing typicality filters to analyze potential event indicators such as alerts. A typicality filter keeps a time-dependent history of the frequency of occurrence of an associated event, wherein time is segmented into monitoring periods. At the end of each monitoring period, a present count of occurrences of the event is determined, and compared with the numbers of occurrences of that event in a subset of monitoring periods read from the history. If the present count exceeds the number of occurrences of the event in a predetermined proportion of the subset of historical monitoring periods, a first action is invoked; otherwise, a second action is invoked.
摘要:
Methods, systems, and computer program products for scheduling task-related activities are disclosed. In one example, the values of a one or more of variables on which an activity is dependent are used to determine the attainability of an activity. Information relating to the variables and/or the attainability of the activity can be recorded, or used to generate notifications and/or invitations for users.
摘要:
A system and method for monitoring the availability of an application in a distributed data processing environment are provided. The performance aspects of application availability are defined in terms of easily observed and computed characteristics of the application as it behaves in a deployed environment with the deployed configuration. The system and method observe the application processes, the structural resources they require, and the consumable resources they require from the running system itself. These observations are then used to derive minimum requirements for the resource requirement aspects of availability as well as derive criteria for normal behavioral conditions. These minimum requirements and normal behavioral conditions are then used to establish monitoring rules or conditions for monitoring the operation of the application to determine if availability of the application is degrading such that a notification needs to be sent to an administrator.
