## Background
BACKGROUND
The present disclosure relates to the field of service quality management, and more particularly to increasing the accuracy of service quality management metrics. Deployment of data services require an industrializing of the carrier's data program and having user experience influence network operations. Service quality management (“SQM”) entails the monitoring and maintenance of end-to-end services for specific customers or classes of customers. Service quality is the collective effect of service performances which determine the degree of satisfaction of a user of the service. A service is a means of delivering value to customers by facilitating outcomes customers/end-users want to achieve but without the ownership of specific costs and risks. SQM allows one to ascertain how a service is performing and how that service is experienced by the user.
FIG. 1 depicts a typical environment for SQM that comprises data sources, a server, and one or more clients. The server has a key quality indicator (“KQI”) combination layer and a service level agreement (“SLA”) layer. The KQI combination layer is where the KQIs are created and the SLA layer is where the SLA is modeled. The service quality data store is where the computed KQIs and received key performance indicators (“KPIs”) are further stored for reporting. Here, granular metrics (“data sources”) are collected for each of the service components that are then used to make a higher-level metric.
The mapping of higher-level metrics to granular metrics is hard-coded; hence, when downstream components are not functioning properly there are gaps in the service quality measurement. Monitoring business services requires the collection of different metrics from a variety of monitoring systems, such as network topology, fault, performance, configuration, and more. Typically, each set of metrics are defined and collected by separate and often isolated, assurance systems. The metrics collected by each assurance system are pre-defined at deployment time.
The metric data is aggregated to determine the overall health of a business service, according to pre-defined service key performance indicators (“KPIs”), which is a type of performance measurement that measure a specific aspect of the performance of either a service resource or a group of service resources of the same type. KPIs are typically restricted to a specific resource type and derived from network measurements. If an assurance system that is providing metrics to the business service management (“BSM”) system in not functioning, there is a gap in metrics obtained, and therefore the business service is deemed to be compromised or degraded.
The current nature of business service management is pre-defined and static, relying on pre-defined metrics being collected by various assurance and resource monitoring systems. If an assurance system is unavailable, this often results in a window of missing data over a period of time, leading to the business service being depicted as in poor health or degraded according to it's KPIs. Current solutions today utilize “self-mirroring” or manage-our-stuff-with-our-stuff, which sends a synthetic alert when one of the monitoring systems that generate service quality data is down. Upon receiving such an alert, the operations staff may take corrective action; however, the service assurance data will still be missing for the time period of the outage.
SUMMARY

DETAILED DESCRIPTION
With reference now to FIGS. 1-5.
The descriptions of the various embodiments of the present invention have been presented for purposes of illustration but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.

In some alternative implementations, the functions noted in the block may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
Deployment of data services require an industrializing of the carrier's data program and having user experience influence network operations. Service quality management (“SQM”) entails the monitoring and maintenance of end-to-end services for specific customers or classes of customers. Service quality is the collective effect of service performances which determine the degree of satisfaction of a user of the service. A service is a means of delivering value to customers by facilitating outcomes customers/end-users want to achieve but without the ownership of specific costs and risks. SQM allows one to ascertain how a service is performing and how that service is experienced by the user.
In SQM, granular metrics are collected for each of the service components that are then used to make a higher-level metric. The mapping of higher-level metrics to granular metrics is hard-coded; hence, when downstream components are not functioning properly there are gaps in the service quality measurement. Monitoring business services requires the collection of different metrics from a variety of monitoring systems, such as network topology, fault, performance, configuration, and more. Typically, each set of metrics are defined and collected by separate and often isolated, assurance systems. The metrics collected by each assurance system are pre-defined at deployment time.
The metric data is aggregated to determine the overall health of a business service, according to pre-defined service key performance indicators (“KPIs”), which is a type of performance measurement that measure a specific aspect of the performance of either a service resource or a group of service resources of the same type. KPIs are typically restricted to a specific resource type and derived from network measurements. If an assurance system that is providing metrics to the business service management (“BSM”) system in not functioning, there is a gap in metrics obtained, and therefore the business service is deemed to be compromised or degraded.
Embodiments of the present invention seek to provide a mechanism for coupling granular metrics with service-level metrics, such that the source of the service-level metric is determined at runtime. Here, the coupling is based on various sources, such as, the best data source based upon the service level agreement (“SLA”); and business service components that are monitored by the monitoring system; attributes of the metrics collected by the monitoring systems.
Embodiments of the present invention will now be described in detail with reference to the Figures. FIG. 2 is a block diagram illustrating an environment, generally designated 200, in accordance with one embodiment of the present invention.
Environment 200 includes monitoring agents 210 and monitoring server 230, all interconnected over network 220. Network 220 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and can include wired, wireless, or fiber optic connections. In general, network 220 can be any combination of connections and protocols that will support communications between monitoring agents 210 and monitoring server 230.
In various embodiments of the present invention, monitoring agents 210 and monitoring server 230 may be a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating via network 220. Monitoring agents 210 are computing devices that monitor a particular aspect of a service, such as fault, configuration, accounting, and performance, in accordance with an embodiment of the present invention. Monitoring agents 210 include exemplary information store 212, which is in communication with system monitor 216. Exemplary information store 212 is an information store that includes data file 214, which includes monitoring data generated by system monitor 216. System monitor 216 is software that monitors system and network applications of network 220 and measures the availability and performance thereof (not shown). System monitor 216 can generate KPIs for the particular service it is monitoring.
Monitoring server 230 is a computing device that facilitates the management of business services, in accordance with an embodiment of the present invention. Monitoring server 230 includes exemplary information store 234, business service manager 232, exemplary information store 242, and program function 240. Exemplary information store 234 is in communication with business service manager 232. Exemplary information store 234 is an information repository that includes service quality data files 238 and service configuration data files 236. Service quality data files 238 are files that include KPIs generated by monitoring agents 210 and received via network 220.
Service configuration data files 236 are files that include modeled service level agreements and similar artifacts, such as customer, service, and contract related information. Business service manager 232 is in communication with exemplary information store 234 and program function 240. Business service manager 232 is software that measures, monitors, and/or models one or more specifics services for the purpose of improving the understanding of the user experience, in accordance with an embodiment of the present invention. Business service manager 232 can receive, via network 220, metrics generated by monitoring agents 210.
Business service manager 232 can receive, via network 220, KPIs generated by monitoring agents 210. Business service manager 232 can generate reports associated with the performance of services monitored by monitoring agents 210 by using generated KQIs. Business service manager 232 can generate KQIs by combining KPIs according to a predefined KQI computation cycle. Business service manager 232 can generate KQIs according to a predetermined periodicity. Business service manager 232 can model service level agreements. Business service manager 232 can display the SLA for a service. Business service manager 232 can generate and/or display information associated with the conformance of a service for a particular KQI.
Exemplary information store 242 is in communication with program function 240. Exemplary information store 242 is an information repository that includes mapping file 248, common information model (“CIM”) file 246, and system id file 244. Mapping file 248 is a data structure that associates system entities, KPIs, and KPI monitoring frequency. A system entity is a person or object for which information is stored. Examples of system entities include, but are not limited to, policy, workflow, account, and service. CIM file 246 includes information that reflects how managed objects in environment 200 are represented as a common set of objects and relationships between them.
In an embodiment, information included in CIM file 246 conforms to the standards defined by the Distributed Management Task Force or Web-Based Enterprise Management. System identification file 244 includes information reflective of the registered monitoring systems associated with network 220, such as monitoring agents 210. Program function 240 is in communication with business service manager 232 and exemplary information store 242, in accordance with an embodiment of the present invention. Program function 240 is software that increases the accuracy of service quality metrics, such as KQIs, in accordance with an embodiment of the present invention.
Program function 240 can transmit instructions to business service manager 232. Program function 240 can generate mapping file 248. Program function 240 can generate CIM file 246. Program function 240 can generate system identification file 244. Program function 240 can determine whether a source for a KPI for a target service element is known. Program function 240 can determine the best source for a KPI. In an embodiment, the best source for a KPI is the source that has the least amount of information gaps as determined by a predetermined periodicity. In other embodiments, information gaps measurements are determined using a predetermined threshold value reflective of an associated information quantity minimum.
FIG. 3 is a flowchart depicting operational steps of program function 240, in accordance with an embodiment of the present invention. The operational steps depicted in FIG. 3 execute subsequent to business service manager 232 configuring the service KPIs. Program function 240 determines whether the source for each KPI for the target system elements is known (decisional 300). A method for discovering is discussed further below in reference to FIG. 4. For example, program function 240 determines if the desired KPI source for a given interface of the target system (not separately shown in the drawings) for a given router of the target system (not separately shown in the drawings) is included in mapping file 248. If program function 240 determines that the source for KPIs for the target system elements are not known (“no” branch, decisional 300), then program function 240 flags that KPI for administrative input (step 302). If program function 240 determines that the source for KPIs for the target system elements are known (“yes” branch, decisional 300), then program function 240 selects the best source for the KPI (step 304). For example, the best KPI source may be determined based upon the associated SLA.
Program function 240 determines whether the KPI was collected more recently than the KQI periodicity (decisional 306). For example, the agent that is included in monitoring agents 210 that generates KPIs for a given interface of the target system may have a periodicity of 2 minutes. If program function 240 determines that the KPI was not collected more recently than the KQI periodicity (“no” branch, decisional 306), then program function 240 returns to step 304. If program function 240 determines that the KPI was collected more recently than the KQI periodicity (“yes” branch, decisional 306), then program function selects the last collected KPI and transmits it to business service manager 232 for feeding the KQI at the next computation cycle (step 308). For example, if the KPI was collected in less than 2 minutes then that particular KPI is utilized at the next computation cycle.
FIG. 4 depicts additional operational steps of program function 240, in accordance with an embodiment of the present invention. Specifically, FIG. 4 depicts the operational steps utilized by program function 240 for discovering and registering existing monitoring systems, which provide the known KPI sources required for the determination of decisional 300 (discussed above). Program function 240 discovers existing monitoring systems associated with environment 200 (step 400). Program function 240 generates a common information model (“CIM”) mapping (step 420). For example, one interface for a router may be identified as “If<12>” in one target system and “IF_IP—12” on another target system. The CIM is one applicable mechanism to correlate disparate events. If no such mechanism is available, a predetermined look up file may be used. For each service item, program function 240 determines the corresponding entities in the registered source systems (step 440). Program function 240 generates a map (step 460). For example, program function 240 generates a hash map that associates entities, KPIs, and/or frequencies, which facilitate the identification of entities across monitoring systems. In an embodiment, the map may be a lookup file or hash table.
