The ONES rule engine enables the detection of incidents and the generation of alerts, but this information is limited to the specific site managed by the corresponding controller. While this data is valuable for data center administrators to address and resolve issues, enterprise-level administrators or executives interested in the overall health of the entire network must access individual ONES instances at each data center to view the status. This process can be inefficient and cumbersome.

To solve this, **ONES Multisite** provides a solution by offering a geospatial representation of anomalies across multiple sites, spread over different geographical locations, giving a comprehensive view of network health. ONES instances from data centers around the world can register with a central **ONES  Multisite application**. Once registered, the multisite system regularly polls each site for key data, such as the number of managed devices (endpoints) and critical alerts, and presents this information on a map, displaying individual sites and their last contact times. Additionally, ONES Multisite allows users to log in to individual data centers to access more detailed information if needed.

#### For a quicker glance about the health conditions, different colors and blinking patterns are used,

* Green blink : Site is reachable with no critical alerts
* Red blink : Site is reachable but there are critical alerts
* Red : Site is not reachable
