Receives messages (for example, PassiveResultMessages) and:
- Forwards them to the correct Collector, using the host to collector mapping stored in the datastore when generating or re-generating collection plans.
- Messages must either be acknowledgements, downtime, Job results or snmptraps.
- Acknowledgement messages have special functionality in that they come in with
host_object_id_listset, then are re-sharded according to ‘host_id’ and sent out to the Collectors (now with ‘host_id’ set).
- For other messages, if ‘host_id’ and ‘object_id’ are set, the messages are sent direct to the correct Collector. If not, then the
object_idare looked up using ‘hostname’ and ‘servicecheckname’ fields, updates the message before re-dispatching.
- Supports multiple worker sub-processes, but is launched by default with only one.
