Cloud refresh interval

IBM® Cloud Manager with OpenStack checks for new images and instances in the cloud and synchronizes the properties for these images and instances.

By default, IBM Cloud Manager with OpenStack receives messages from the cloud to synchronize with the cloud manager. The frequency of this synchronization is determined by the com.ibm.cfs.cloud.refresh.interval property in the cloud.properties file. If the property is not set, a default of 30 seconds is used.

IBM Cloud Manager with OpenStack scans the cloud for updates on instances as often as the refresh interval property specifies. However, you can change the synchronization mode so that IBM Cloud Manager with OpenStack periodically checks with the cloud without waiting for messages.

For more information about setting the synchronization mode, see Configuring cloud synchronization mode.
