The ESI Service has a System Refresh Interval setting for how often it polls all registered storage systems and populates the entity graph with all discovered storage systems and system components. The ESI Management Packs use this information to confirm and update to the most current data about discovered components.
By default, this interval is set to poll
the storage systems every 30 minutes for new information. This
setting, combined with the ESI Monitoring management pack interval
number, is the set frequency for receiving monitor updates in SCOM.
For example, with this interval set to 30 minutes and the ESI
Monitoring interval override set to 10 minutes, an updated health
state can take up to 40 minutes. The time intervals can affect the
data performance. Changing discovery
interval overrides provides details on the Monitor interval
