[SNMP4J] SnapshotAgent

[Mathieu Pelletier]

No... it was my first intuition however.

I tried to disable the log by specifying a log4j.properties as a system
property to the application. However, the file doesn't seems to be used.

While checking the source code I saw this section:
  static {
    LogFactory.setLogFactory(new Log4jLogFactory());
  }

I guess it's overwrite my configuration.

I tried also to redirect the output to /dev/null. Seems to help.

Can you disable the logging using the default built library?

Thank you Frank
