Abstract

Service Level Agreements (SLAs) provide the ability for a service provider to guarantee a committed level of service to a specific customer set. In today's environment, the system management resources used to provide the services often change. This article describes a methodology for providing Service Level Agreements where large numbers of monitored resources can change dynamically without changing the Service Level Agreement

Dynamic SLAs Based on Wild Card Resource Lists

  Disclosed is a process for implementing rule based Service Level Agreements (SLAs). Rule based SLAs allow resources that pass the rule filter to dynamically be included into a metric evaluation without changing the SLA. The rule filter must be passed to each processing component (GUI, Metric Evaluation, Data Collection, and Reports) in the end-to-end process.

For SLA Management (and systems management in general) an administrator usually uses a GUI to determine the resources to monitor as part of the service. This is difficult for some services (a web site for example) with a large number of resources to monitor. In addition the resources associated with the service can change over time as upgrades or other changes are made to the service. The approach take in this disclosure is to apply the rule to not only the GUI selection, but to the entire data flow. GUIs commonly allow wildcard selection or rule filtering, but that selection usually returns a long list of items, which are handled individually. The approach taken with this disclosure is to flow the rule in the data flow so that the list of resources is dynamically generated.

The key components used in rule based SLA processing flow are the GUI, Evaluation,

Data Collector, Database, and Reports. The following is a description of each of the key components.

10 GUI - The GUI component provides the visual representation of the rule to the end user. A list of current resources that pass the filter is required so that the user can validate the rule produces the correct resource list. For rule based SLAs the rule is saved as part of the SLA for use when the SLA is evaluated. 20 Evaluation - The evaluation component validates that measurements such as response time for a resource are within the constrai...
