Well, that's not really true. I have a feeling there is a misunderstanding of the documentation: https://xrootd.slac.stanford.edu/doc/dev55/xrd_monitoring.htm#_Toc99653755 Note that the following timing structure is always sent in each packet: struct XrdXrootdMonFileTOD { XrdXrootdMonFileHdr Hdr; // recType == isTime int tBeg; // time(0) of following record int tEnd; // time(0) when packet was sent kXR_int64 sID; // Server identifier lower 48 bits }; So, tBeg &and* tEnd are always sent that this established the time window of the packet. So, you mant to print both of those just before the packet is sent out. -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1988#issuecomment-1536948835 You are receiving this because you commented.
