How can I log request and response with "smallrye-graphql-client-implementation-vertx" ?

[jmini]

I am currently trying the typesafe client with smallrye-graphql-client-implementation-vertx instantiated from a simple main class:

SuperheroesClientApi api = TypesafeGraphQLClientBuilder.newBuilder()
                                                        .build(SuperheroesClientApi.class);

Source: Client.java

---

In Quarkus I know that there is an option to log client and response:

quarkus.log.category."io.smallrye.graphql.client".level=TRACE
quarkus.log.category."io.smallrye.graphql.client".min-level=TRACE

---

Is there something similar in io.smallrye:smallrye-graphql-client-implementation-vertx, and how can I enable this?

I have tried to search for modifying log level org.jboss.logging:jboss-logging but the search results are pointing to changing log levels inside the JBoss app server. I was not able to understand how it can be configured programmatically

I'd actually be interested in learning this too. Maybe @jamezp can help us - what is the easiest way to get a standalone (Java SE) application that uses the JBoss Logging API to actually log something? It's hard to find any documentation that is not specific to WildFly or Quarkus.

^ Very good summary of my question 👍

[jamezp]

JBoss Logging is just a logging facade. If you want a log manager you'd have to use something like JUL or JBoss Log Manager. I can give some instructions for that if it helps.

A link to some documentation would be wonderful 😁 AFAICS, the JBoss Log Manager is a nice, mature, and powerful piece of software. It only lacks publicly available documentation.

I've submitted #2209 to provide a simple example in our docs

Ok I found everything I needed:

JBoss Logging is the facade (like slf4j):
https://github.com/jboss-logging/jboss-logging
--> smallrye-graphql-client-implementation-vertx has already a dependency on it.

By default it seems to do something, but I am not sure if this is configurable and how.

JBoss Log Manager can control what is logged and where (like logback)
https://github.com/jboss-logging/jboss-logmanager

• It has to be added on the runtime classpath
• It has to be enabled with -Djava.util.logging.manager=org.jboss.logmanager.LogManager when the Java SE process is started
• The configuration file logging.properties can be in the jar, so a simple way is to add it to src/main/resources

About the configuration file:

I found this example: logging.properties from jamezp/jboss-logging-example

I simplified it (I removed what I did not understood) and I managed to enable:

• DEBUG level for my main class: run.Client
• TRACE level for for io.smallrye.graphql.client (similar to what is recommended by quarkus)

Nice @jmini, thanks for digging into it! I'll add something like this to the SmallRye GraphQL docs!
