System state changes

These events occur when the system is running. The typical states are

• Online
• Pausing Now
• Going Pre-Online
• Resuming
• Going OffLine Now
• Offline (now)
• Initializing
• Stopped

The Failing Back and Synchronizing states apply only to z-series systems.

The following is the syntax for the template event rule NPSNoLongerOnline:

-name NPSNoLongerOnline -on no -eventType sysStateChanged 
-eventArgsExpr '$previousState == online && $currentState != online' 
-notifyType email -dst 'you@company.com' -ccDst '' -msg 'NPS system 
$HOST went from $previousState to $currentState at $eventTimestamp 
$eventSource.' -bodyText '$notifyMsg\n\nEvent:\n$eventDetail\n' 
-eventAggrCount 1

The following is the syntax for event rule SystemOnline:

-name SystemOnline -on no -eventType sysStateChanged -eventArgsExpr 
'$previousState != online && $currentState == online' -notifyType 
email -dst 'you@company.com' -ccDst '' -msg 'NPS system $HOST went 
online at $eventTimestamp $eventSource.' -bodyText 
'$notifyMsg\n\nEvent:\n$eventDetail\n' -eventAggrCount 
50

The valid values for the previousState and currentState arguments are:
