Detailed Description

The memhandler will generate events for memory use: total used, total free, percent used and percent swap used.

Wire keywords (standard handler keywords documented in Wire )

• totalused: event (optional)
• totalfree: event (optional)
• percentused: event (optional)
• percentswapused: event (optional)

Example:

  // monitor used mem (as a percentage) every minute
  set percentused  create event { name: "%mem on server"  priority: 1 }
  create handler mem { percentused: $percentused cycletime: 60 }

Events generated:

Event Name	Type	Description
totalused	AW_EVENT_TYPE_INT32	Total used memory (KB)
totalfree	AW_EVENT_TYPE_INT32	Total free memory (KB)
percentused	AW_EVENT_TYPE_FLOAT32	Percent of total memory used
percentswapused	AW_EVENT_TYPE_FLOAT32	Percemt of swap used
