System Center Global Service Monitor is a cloud service that provides a simplified way to monitor the availability of external-web-based applications from multiple locations around the world. Importantly, Global Service Monitor monitors applications from the perspective of the customers who use them. Because Global Service Monitor monitors from locations that are correlated to customer geographies, application owners can gain insight into customer experiences in addition to the separate problems related to external factors, such as Internet or network problems, from application or service problems. The Global Service Monitor monitoring experience focuses on the application instead of the infrastructure or individual URL.

Global Service Monitor integrates with the Operations Manager console so that you can monitor external- and internal-facing web applications in the same place you monitor other applications.

Global Service MonitorMonitoring Capabilities

With Global Service Monitor, the Operations Manager console integration lets you monitor web applications from both internal and external locations. In Global Service Monitor, you can use your management group and obtain access to agents in the cloud provided by Microsoft. This lets you monitor web applications from 15 locations and then report back to your management group. You can also use your own agents as watcher nodes to monitor internal locations and applications.
