When people think about high-quality network and application performance, their attention is appropriately on assuring the most important business-critical applications. However, there is a supporting set of services that are necessary for any user, networking device, and/or application to simply operate. These are known as service enablers, and they provide authentication, network privileges, DNS, and other critical ancillary functions. Performance visibility for service enablers is a priority to help avoid or quickly rectify issues that might cause a slow-down or an outage that can affect multiple mission-critical applications. This white paper covers challenges, benefits, value, use cases, and instrumentation strategies for performance monitoring and management of service enablers.
