brooklyn.event.adapter
[Groovy] Class ShellSensorAdapter

java.lang.Object
  brooklyn.event.adapter.AbstractSensorAdapter
      brooklyn.event.adapter.FunctionSensorAdapter
          brooklyn.event.adapter.ShellSensorAdapter

class ShellSensorAdapter
extends FunctionSensorAdapter

Like FunctionSensorAdapter but executes a shell command (on the local machine where this instance of brooklyn is running). Useful e.g. for paas tools such as Cloud Foundry vmc which operate against a remote target.

Example usage: def diskUsage = sensorRegistry.register(new ShellSensorAdapter("df -p")) diskUsage.then(&parse).with { poll(DISK0_USAGE_BYTES) { it[0].usage } poll(DISK0_FREE_BYTES) { it[0].free } }

See also FunctionSensorAdapter (for arbitrary functions) and SshSensorAdapter (to run on remote machines).
