Hi Lukasz, We ((US)CMS) are thinking about sending custom session information from xrootd jobs via the user-info detailed monitoring messages (the 'i' message). Andy said he suspects that the interface to do this is not available in the "old" client. As CMS will probably use the old client throughout 2012 I'd be willing to get it implemented for the next 3.X release. Does this sound good to you? Writing this I realized I don't really know what's the status of the new client and at what point it will get pushed into the releases. Will this be 4.X? Best, Matevz ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-DEV&A=1
