Cisco Crosswork Network Controller 7.2 Service Health Monitoring

Basic and advanced monitoring rules, subservices, and metrics

Service Health monitoring in Cisco Crosswork Network Controller provides two distinct monitoring levels—Basic and Advanced—that enable scalable and detailed service performance assessment. These monitoring rules leverage Heuristic Packages to evaluate service components and metrics, empowering network operators to maintain service integrity and quickly identify issues impacting network services.
