Maybe a stupid question, but we upgraded from version 0.17 to 0.18.2 and now get tons of log messages like this

14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_39' -> 'fixedsize' has its default value 'false'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_40' -> 'fontcolor' has its default value 'black'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_40' -> 'height' has its default value '0.5'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_40' -> 'penwidth' has its default value '1.0'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_42' -> 'fontcolor' has its default value 'black'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_42' -> 'penwidth' has its default value '1.0'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_42' -> 'fixedsize' has its default value 'false'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_43' -> 'fontcolor' has its default value 'black'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_43' -> 'penwidth' has its default value '1.0'. 14:33:04.318 [Worker-8: Building] INFO guru.nidi.graphviz.model.Serializer - INFO node 'NODE_43' -> 'fixedsize' has its default value 'false'.

How can I turn of this messages?

Thanks, Max

No hint from nobody?

You can try the no-operation (NOP) logger implementation.

Hope it helps.

As always, if you know how it is simple :-)

import org.slf4j.LoggerFactory; import ch.qos.logback.classic.Logger import ch.qos.logback.classic.Level

Logger root = ( Logger) LoggerFactory.getLogger(org.slf4j.Logger.ROOT_LOGGER_NAME) root.setLevel(Level.ERROR);
