logs cleanup - web viewer [message #644981]

The birt viewer web app has a 'logs' directory as defined by BIRT_VIEWER_LOG_DIR in web.xml. Anybody know there's a mechanism for cleaning up old logs from this directory? Mine just keeps filling up (actually caused the app to fail!).

Josh,

I know the team has added
config.setLogMaxBackupIndex(int);
config.setLogRollingSize(int);
to the EngineConfig, but I do not think its in the viewer yet.
You may want to log a bug for this.

Also you could look at using log4j

logMaxBackupIndex actually defaults to 1 (so no need to explicitly set it). It only helps if it's a single file being 'rolled over' due to reaching the predefined size, however the Birt Viewer creates files with unique filenames so they're never very large, but there are many of them. logMaxBackupIndex won't help here.

Ideally I'd like to pass my web application's Apache commons logger to the BIRT engine config, however BIRT uses JDK logging, and I can't figure out how to do that. The following snippet describes what I'd like to do:-

Log log = LogFactory.getLog(this.getClass()); // Get Apache commons Log
ReportEngineService.getInstance().getEngineConfig().setLogger(log); // Type mismatch!

Are there any suggestions on how I might do this?

Josh,

I have not tried this before. Have you tried the method described here:
