If an application inside a pod, such as the ODL, dies or is stopped, the pod itself will be recreated so the outage will be seen as with a pod outage.
The operator of the site can use this information to help determine when a manual failover to the remote site is required. Normally, a failover would be desired when there is a lack of redundancy available for a component, such as when only one database is available or when only one ODL is available. The operator would first want to determine whether the site that has experienced the outage(s) is the 'active' site by running the '/optdockerdata-nfs/sdnccluster/georscript/sdnc.cluster' script.
