gordon,

  Thanks much, it works by adding below section in pipeline.yaml

    - name: collectd_source
      interval: 60
      meters:
          - "load.load"
          - "memory.memory"
          - "interface.if_dropped"
          - "interface.if_errors"

    - name: collectd_sink
      transformers:
      publishers:
          - notifier://


   Another question, what is the difference between ceilometer backend
database with the database:// configured in publishers? If I didn't set
'backend=xx' in ceilometer.conf but set
'connection=mongodb://user:password@ip_address/ceilometer', seems it
connected to mongodb other than any backend options(sqlalchemy, mysql,etc),
does the database:// configured in publishers should be actually
'mysql://user:password@ip_address/ceilometer' ?


Thanks.
Hui.
