Artemis Parameter Publisher

Publish param stream data to an Artemis broker.

Class Name



This service is defined in etc/yamcs.(instance).yaml. Example from a typical deployment:

  - class: org.yamcs.artemis.ArtemisPpService
    args: [pp_realtime, pp_dump, sys_param]

args must be a an array of strings indicating which streams to publish. For each stream the target address is composed as In the example tuples from the streams pp_realtime, pp_dump and pp_dump are published to the addresses simulator.pp_realtime, simulator.pp_dump and simulator.pp_sys_param respectively.

By default, messages are published to an embedded broker (in-VM). This assumes that Artemis Server was configured as a global service. In order to use an external broker you can configure the property artemisUrl in either etc/yamcs.(instance).yaml or etc/yamcs.yaml:

artemisUrl: tcp://remote-host1:5445
artemisUrl: tcp://remote-host1:5445

If defined, the instance-specific configuration is selected over the global configuration. The URL format follows Artemis conventions and is not further detailed in this manual.
