This is probably a stupid question, but my scala knowledge is a bit lacking. I'm trying to implement structured logging in scala, and we're using slf4j/logback/logstash. I came across the following post: How does SLF4J support structured logging Which describes how to do it:
import static net.logstash.logback.argument.StructuredArguments.*;
/*
* Add "name":"value" ONLY to the JSON output.
*
* Since there is no parameter for the argument,
* the formatted message will NOT contain the key/value.
*
* If this looks funny to you or to static analyzers,
* consider using Markers instead.
*/
logger.info("log message", keyValue("name", "value"));
Obviously this is java code, not scala. I've converted it over, but I can't get it to find net.logstash.logback.argument.StructuredArguments.KeyValue. I'm guessing this is because it's not being included in the build, but this is where I'm tripping up.
I'm using sbt, and I'm including what I expect the package to be:
"net.logstash.logback" %% "logstash-logback-encoder" % VersionOf.`logstash`
However sbt cannot find that package (version is 1.2.1). What's also confusing me is that our other dependencies for logback are pulled from the group id: ch.qos.logback. I don't really understand what ch.qos.logback is and why it's different from net.logstash.logback.
Long story short, what package do I need to import with sbt so that I can use StructuredArguments/KeyValues for my logging?
