Subscriptions in the VergeIO platform are where administrators configure alert notifications to monitor the overall health of the system. There are two types of alert subscriptions: On demand or scheduled.
On demand alerts are primarily used to assist in monitoring changes in the system. Some examples are:
Scheduled subscriptions are typically used to monitor changes over a period of time. Tracking a particular vSAN tier's growth history, weekly, is a good example of a scheduled subscription.
In addition to a number of built-in subscriptions to the VergeIO platform, administrators can build custom subscriptions to monitor particular changes. Custom subscriptions can be created with a working knowledge of the API.
