Trace options
You can enable trace to provide information about your environment to IBM support.
About trace
WebSphere eXtreme Scale trace is divided into several different components. Similarly toWebSphere Application Server trace, you can specify the level of trace to use. Common levels of trace include: all, debug, entryExit, and event.An example trace string follows:
ObjectGridComponent=level=enabled
You can concatenate trace strings. Use the * (asterisk) symbol to specify a wildcard value, such as ObjectGrid*=all=enabled. If you need to provide a trace to IBM support, a specific trace string is requested. For example, if a problem with replication occurs, the ObjectGridReplication=debug=enabled trace string might be requested.
