The Sensu Event Streamliner is a Sensu Mutator that removes certain redundant event information that may not be needed in certain situations (e.g. sending off to an event indexer).

The event fields removed are:

• event.Entity.Redact
• event.Entity.System.Network.Interfaces
• event.Entity.Subscriptions
• event.Check.Handlers
• event.Check.History
• event.Check.RuntimeAssets
• event.Check.Subscriptions

My anecdotal testing has shown that this reduces the event payload sent to a handler by between one and two KiB per event.

There are no arguments to this mutator, so the usage is quite simple.
