Detailed Description

The mounthandler will poll the used, available and percent used 1K blocks for a filesystem (similar to 'df').

Wire keywords (standard handler keywords documented in Wire )

• filename: filesname in filesystem
• used: event (optional)
• avail: event (optional)
• percentused: event (optional)

Example:

  // monitor log partition
  set percentused create event { name: "/log"  priority: 1 }
  create handler mount { filename: /log percentused: $percentused cycletime: 300 }

Events generated:

Event Name	Type	Description
used	AW_EVENT_TYPE_INT32	Number of 1K blocks used
avail	AW_EVENT_TYPE_INT32	Number of 1K blocks available	percentused	AW_EVENT_TYPE_FLOAT32	Percent used

Events accepted:

Type	Description
Any	Causes requested events to be generated
