Use the Horizon Adapter Self Health dashboard to view health information for vRealize Operations for Horizon adapters and for the vRealize Operations for Horizon broker agents that are connected to those adapters. You can also use the Horizon Adapter Status dashboard to verify license compliance.
The Select Horizon Adapter widget is the master widget for the adapter-related widgets on the dashboard. When you select an adapter in the Select Horizon Adapter widget, the Horizon Adapter Statistics and Horizon Adapter Status widgets show data for the adapter that you selected.
The Select Horizon Broker Agent widget is the master widget for the broker agent-related widgets on the dashboard. When you select a broker agent in the Select Horizon Broker Agent widget, the Horizon Broker Agent Event DB Collection Statistics, Horizon Broker Agent Metric Collection Statistics, Horizon Broker Agent Topology Collection Statistics, and Horizon Broker Agent Status widgets show data for the broker agent that you selected.
Tips for Using the Horizon Adapter Self Health Dashboard
Use the Horizon Adapter Status widget to view important metrics for the selected adapter, including the length of the last collection period, the number of desktops that sent data samples during the last collection period, and the total number of objects that the adapter received during the last collection period.
Use the Horizon Broker Agent Status widget to view important metrics for the selected broker agent, including the topology, metric, and database event collection times and the user session, desktop virtual machine, and database event record counts.
Use the License Usage History widget to check license compliance during the past 30 days. This graph tracks the number of concurrent users connected to the Horizon environment.
Use the Active License Alerts widget to view open license alerts associated with the Horizon adapter that you selected. You can double-click an alert to view information about its possible cause and its effect on your environment.
Horizon collection statistics for the selected broker agent in the Horizon Broker Agent Topology Collection Statistics, Horizon Broker Agent Metric Collection Statistics, and Horizon Broker Agent DB Event Collection Statistics widgets. These widgets show simple graphs that contain the values of their associated collection metrics over time.
Understanding Broker Agent Metrics
Although the broker agent metrics on the Horizon Adapter Status dashboard are accurate, their values might be misleading. Because these metrics correspond to different activities within the broker agent, they are updated at different intervals. For this reason, some metrics might appear to be stale or not up-to-date.
For example, the Topology Collection Time, User Session Count, and Desktop VM Count metrics in the Horizon Broker Agent Status widget are updated only once per hour. Because the User Session Count metric value can be up to an hour old, it might not agree with the session count value that appears on other dashboards.
In another example, the DB Event Collection Time and DB Event Record Count metrics might show a question mark (?) to indicate that there is no data, even though data has been collected. This situation occurs when no relevant vRealize Operations for Horizon database events are collected during the last six hours because these metrics are updated only when the broker agent sends events (for example, session connection and Horizon error events) to the adapter.
In general, metric collection metrics are sent every five minutes and topology collection metrics are sent every hour. Database event collection metrics might be sent as often as once per minute or as seldom as there are relevant vRealize Operations for Horizon events.
