Automated Live Debugging Using Real-Time Data Processing, Nivetha B, Santosh Rathod

Defensive Publications Series

In a customer service call center, when an issue is reported by a customer, a SR (service request) is logged. Often, additional logs are needed to resolve the SR; typically, an engineer connects with the customer over a live maintenance window (MW) to address the issue. Solving an issue can also be quite long or can involve scheduling multiple MWs before a root cause is identified. Thus, issues with maintenance windows, scheduling such windows, and potentially having multiple customer interactions to fully address an issue can impact a company's ability to provide quality service to the customer. Techniques to address …
