Filed:

Apr 7, 1999

Appl. No.:

09/287601

Inventors:

Yiping Ding - Dover MA
Kenneth Newman - Cambridge MA

Assignee:

BMC Software, Inc. - Houston TX

International Classification:

G06F 1900

US Classification:

702186, 709224, 709226

Abstract:

A system and method for estimating statistics concerning system metrics to provide for the accurate and efficient monitoring of one or more computer systems. The system preferably comprises a distributed computing environment, i. e. , an enterprise, which comprises a plurality of interconnected computer systems. At least one of the computer systems is an agent computer system which includes agent software and/or system software for the collection of data relating to one or more metrics, i. e. , measurements of system resources. Metric data is continually collected over the course of a measurement interval, regularly placed into a registry of metrics, and then periodically sampled from the registry indirectly. Sampling-related uncertainty and inaccuracy arise from two primary sources: the unsampled residual segments of seen (i. e. , sampled and therefore known) events, and unseen (i. e.

Assignee:

BMC Software, Inc. - Houston TX

International Classification:

G06F 9/46

US Classification:

718104, 718105, 705 7

Abstract:

A system and method for automatic workload characterization are provided. Transactions performed in a computer system may be logged. The log of transactions comprises a timestamp for each transaction. Resource usage in the computer system may be logged. The log of resource usage comprises one or more periods of time during which each of a plurality of resources is used, and the log of resource usage comprises a plurality of system performance metrics which reflect resource consumption by one or more processes that performed the transactions. The timestamps in the log of transactions may be compared to the periods of time in the log of resource usage. It may be determined which transactions used which resources as a result of the comparing the timestamps in the log of transactions to the periods of time in the log of resource usage. One or more workloads may be determined using the determining which transactions used which resources. Heuristics may be used to group processes into workloads.

International Classification:

G06F 11/30
G06F 15/00
G21C 17/00

US Classification:

702182

Abstract:

A method using statistical parameters (e. g. mean, standard deviation, exceptional values) of performance monitoring metrics to substantially reduce the quantity of performance monitoring data collected and reported, make system performance monitoring scalable and enhance the readability of the system performance display. The number of metrics monitored may be reduced by monitoring only one of any two metrics that are closely correlated.

Abstract:

A novel method of and system and procedures for more accurately measuring the resource usage of UNIX processes by sampling methods involving appropriate corrections for the resource usage of the terminated processes and analyzing UNIX process data along with subsystem data such as RDBMSs, allowing system administrators and mangers to get a much better picture of who is using the resources on the system and thus perform a better job at performance analysis and capacity planning, the technique also enabling and reducing the error in the process measurements collected by sampling of the resources usage measured by the operating system and correlating the measurements taken by subsystems with the measurements taken by the operating system.
