EVENT MESSAGE not populating model about ladder99

[bburns]

Oh, messages require an additional field. From https://github.com/mtconnect/cppagent#adapter-agent-protocol-version-17 -

The next special format is the Message. There is one additional field, native_code, which needs to be included: 2014-09-29T23:59:33.460470Z|message|CHG_INSRT|Change Inserts

For now I just did like so - in future we can try the DATA_SET representation -

  - key: dev_msg
    category: EVENT
    type: MESSAGE
    value: "Object.entries(<status-faults>).map(([id, fault]) => fault.description).join(', ')"
    nativeCode: NativeCode

---

Agent shows eg

<Message dataItemId="pa1-dev_msg" nativeCode="NativeCode" sequence="138" timestamp="2021-08-06T09:25:45.538Z">hard fault 1</Message>

For Agent debugging, the trace level includes the shdr inputs - https://github.com/mtconnect/cppagent#logger_config-configuration-items

logger_config {
   logging_level = trace
}

agent | 583479 TRACE [3] input.connector: (Port:53511) Received line: '2021-08-06T09:25:04.370Z|pa2-feed_message|NativeCode|printer service required, take up motor timeout, low ribbon'

I used ag to help debug it (like grep but colors matches) -
