Architecture

The Watcher process take care of the connection of various node. You can request it to add node, obtain from it the list of node and register to receive events about node from it.

Methods:

• add_node(node_name)
• remove_node(node_name)
• register_for_events(pid // self)

Event raised from Watcher:

• {:node_added, %NodeInfo{}}
• {:node_removed, %NodeInfo{}}
• {:node_down, %NodeInfo{}}
• {:node_up, %NodeInfo{}}

The Logger write in the application logger alla teh events that appen at application level:

• {:node_added, %NodeInfo{}}
• {:node_removed, %NodeInfo{}}
• {:node_down, %NodeInfo{}}
• {:node_up, %NodeInfo{}}

The SMSNotififier send SMS to every registered number info about the event that happen to the nodes. In this module we can select whit event we want receive on SMS and on which phone number.

The MailNotififier send Mail to every registered mail address about the event that happen to teh nodes. In this module we can select whit event we want receive on SMS and on which phone number.
