<PRE>Thanks for this.  I've tried it.  It seems to be adding a trace to an 
already existing log file (which is already handling log messagse of a 
certain level).  e.g., it uses lager:trace not lager:trace_file.

I can't set it up so the trace file receives *only* trace messages.  I'l 
revert to the lager:trace_file call.

Best wishes

Ivan


Below is the config I've been using.

  {lager, [
           {handlers,
	   [
	    {lager_console_backend, info},
	    {lager_file_backend,
	     [
	      [{file, &quot;log/error.log&quot;}, {level, error},
                {size, 10485760},
	       {date, &quot;$D0&quot;}, {count, 5}],
	      [{file, &quot;log/console.log&quot;}, {level, info},
                {size, 10485760},
	       {date, &quot;$D0&quot;}, {count, 5}],
	      [{file, &quot;log/access.log&quot;},
                {size, 10485760},
	       {date, &quot;$D0&quot;}, {count, 5}]
	     ]}
	   ]},
	  {traces,
	   [
	    {{lager_file_backend, &quot;log/access.log&quot;},
              [{type, access}], debug}
	   ]}
          ]},
