EMA tracing of incoming messages with XmlTraceRead=1 to file(s) does not work properly.

Reactor read messages are written to files only when XmlTraceToFile=1, XmlTraceRead=1 and XmlTraceToStdout=1. Simultaneosly these messages logged to stdout as well.

It seems there is an error in the code, see https://github.com/Refinitiv/Real-Time-SDK/blob/206e4e5a3255da3afcfa75f5da151a8efef6de8e/Java/Eta/ValueAdd/src/main/java/com/refinitiv/eta/valueadd/reactor/Reactor.java#L4809

I guess it should be _reactorOptions.xmlTraceToFile() instead of _reactorOptions.xmlTracePing() in the if condition.

RTDSK version is 3.7.3.0

To reproduce use the following XML configurations and compare the logs:

<?xml version="1.0" encoding="UTF-8"?><EmaConfig>
<ConsumerGroup>
<DefaultConsumer value="Consumer_0"/>
<ConsumerList>
<Consumer>
<Name value="Consumer_0"/>
<ChannelSet value="Channel_0"/>
<XmlTraceRead value="1"/>
<XmlTraceToFile value="1"/>
<XmlTraceFileName value="ema-trace"/>
<XmlTraceToMultipleFiles value="1"/>
<XmlTraceMaxFileSize value="100000"/>
</Consumer>
</ConsumerList>
</ConsumerGroup>
<ChannelGroup>
<ChannelList>

<Host value="localhost"/>
<Port value="14002"/>
</Channel>

    Hello @VadimVashkevich

    Thank you for reaching out to us. I can replicate the same behavior with EMA Java 3.7.3.0 and ex100_MP_Streaming example. My EmaConfig.xml file is as follows:

    <Consumer>
        <!-- Name is mandatory    -->
        <Name value="Consumer_1"/>
        <!-- Channel is optional: defaulted to "RSSL_SOCKET + localhost + 14002" -->
        <!-- Channel or ChannelSet may be specified -->
        <Channel value="Channel_1"/>
        <!-- Dictionary is optional: defaulted to "ChannelDictionary" -->
        <Dictionary value="Dictionary_2"/>
        <XmlTraceToStdout value="0"/>
        <XmlTraceToFile value="1"/>
        <XmlTraceFileName value="C:\\logs\\api.log"/>
    </Consumer>
    • With <XmlTraceToFile value="1"/> + <XmlTraceToStdout value="0"/>, the API logs only outgoing messages
    • With <XmlTraceToFile value="1"/> + <XmlTraceToStdout value="1"/>, the API logs both incoming and outgoint messages

    I have created the GitHub - Issue #273 on your behalf on the RTSDK GitHub repository. You can track the issue or contact the RTSDK team directly via this https://github.com/Refinitiv/Real-Time-SDK/issues/273 link.
