This High-Level Enterprise Systems Monitoring (ESM) Pattern represents a work in progress and will continue to change as the ESM market matures and its component technologies evolve. Several of the components in the diagram are represented with a dashed line, which indicates a potential future development for NIH.
Business Service Management is depicted as future functionality at the top of the diagram and represents how NIH would align IT infrastructure and applications with the business processes they enable. Business Service Management, when properly implemented, will provide NIH with level 4 capabilities in the Effective Process Development Maturity Model.
Event Management and Problem Management are two critical components of ESM. Information from other ESM disciplines like Availability, Performance, Security, Configuration Management and Change Management are correlated in the Manager of Managers. The Manager of Managers then interacts closely with the Problem Management system by triggering trouble tickets or incident reports.
The Availability Management disciplines are represented in the lightly shaded rectangle on the left of the pattern. Five services monitor, collect and correlate the data from the managed elements. Availability Management tools provide proactive and predictive capabilities. They typically provide data on the health of the managed elements to support a dashboard view of systems availability.
Performance Management represents the trending of end-to-end response time and network, system and application component performance parameters to predict short-term future performance degradation and has direct interfaces to the Managed Elements and the Event Manager of Managers.
Security Management, Configuration Management and Change Management are each displayed as future elements to the diagram; however, the basic interaction with the in-scope elements is depicted.
Managed Elements at the bottom of the diagram show which technical components are in scope for this iteration of the ESM Architecture. Future architecture efforts could extend the elements that are managed by ESM to include new technologies, workstations and additional applications.
The Scripts and/or Agents are software that reside on the managed elements and interact with the management tools through various communication protocols: Simple Network Management Protocol (SNMP), Common Management Information Protocol (CMIP), Java Management Extensions (JMX) and Web Site Design Method (WSDM), or remote procedure calls (RPC). The actual mechanism used for each interaction between the ESM tools and the managed elements is determined by the chosen tool.
