How to ignore default fields

Hi,

could you please document, how default fields could be ignored? For me, there is no use for these default fields: logger_name, thread_name, level, level_value, HOSTNAME and I want to get rid of them. The single-word names are ignored by just <level>[ignore]</level> (as documented) but the two-word names are not so obvious. By little experimenting, I found almost all keys logger_name = logger, thread_name = thread, level_value = levelValue but I am not able to find out correct key for HOSTNAME.

Thanks jama707, your last reply was pretty helpful, and yes, there should be consistency. Now, this works:

        <encoder class="net.logstash.logback.encoder.LogstashEncoder">
            <includeContext>false</includeContext>
            <includeCallerData>true</includeCallerData>
            <fieldNames>
                <timestamp>timestamp</timestamp>
                <message>message</message>
                <thread>[ignore]</thread>
                <logger>[ignore]</logger>
                <version>[ignore]</version>
                <levelValue>[ignore]</levelValue>
                <caller>trace</caller>
                <stackTrace>exception</stackTrace>
                <mdc>context</mdc>
            </fieldNames>
        </encoder>

logger_name, version, thread_name, level, level_value are not in the MDC.

To disable those, you’ll need to set their field names to [ignore] as mentioned here

I’ve never seen logs.home before, so I’m not sure where that is coming from.

However, if you are removing all the default fields, I would suggest using the composite encoder instead of the LogstashEncoder. The composite encoders allow you to selectively add things as needed (rather than removing things).
