Enable logging for queries

[Ankur Goel]

Hi,

I am using JanusGraph 0.1.1. And using logback:

       <logger name="org.janusgraph" level="DEBUG" additivity="false">

<appender-ref ref="CONSOLE" />

</logger>

<logger name="org.apache" level="DEBUG" additivity="false">

<appender-ref ref="CONSOLE" />

</logger>

        <root level="debug">

<appender-ref ref="CONSOLE" />

</root>

This result in following output only:

15:28:23,108  INFO ReflectiveConfigOptionLoader:173 - Loaded and initialized config classes: 9 OK out of 12 attempts in PT0.018S

15:28:23,171  INFO Reflections:224 - Reflections took 38 ms to scan 1 urls, producing 12 keys and 25 values

15:28:25,409  INFO CassandraThriftStoreManager:628 - Closed Thrift connection pooler.

How i can enable logging to see the internals and queries fired against JanusGraph.

Hi Ankur,

Gremlin-server 3.3.0 has an audit log feature based on the authentication.enableAuditLog property, so you can expect this in one of the next Janusgraph  releases. I did not look into logging features of JanusGraph itself.

Take a look at your classpath loading order to make sure that logback is getting selected as the binding for SLF4J.
If a different logger is getting picked up before it, like log4j12, then it won't matter what configuration you have in your logback.xml.
See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

Thnx Got the problem resolved:

As per SLF4j:

Embedded components such as libraries or frameworks should not declare a dependency on any SLF4J binding but only depend on slf4j-api. When a library declares a compile-time dependency on a SLF4J binding, it imposes that binding on the end-user, thus negating SLF4J's purpose. When you come across an embedded component declaring a compile-time dependency on any SLF4J binding, please take the time to contact the authors of said component/library and kindly ask them to mend their ways.

Request to exclude following dependency 

<groupId>org.slf4j</groupId>

<artifactId>slf4j-log4j12</artifactId>

from JanusGraph.

<groupId>org.janusgraph</groupId>

<artifactId>janusgraph-es</artifactId>

<artifactId>janusgraph-cassandra</artifactId>

<artifactId>gremlin-driver</artifactId>

Logging will start working.
