Hello Andrew,
My goal was to check every gstream event generate on the
file XrdPfc/XrdPfc.cc by:
644 int len = snprintf(buf, 4096, "{\"event\":\"file_close\","
645
"\"lfn\":\"%s\",\"size\":%lld,\"blk_size\":%d,\"n_blks\":%d,\"n_blks_done\":%d,"
646
"\"access_cnt\":%lu,\"attach_t\":%lld,\"detach_t\":%lld,\"remotes\":%s,"
647
"\"b_hit\":%lld,\"b_miss\":%lld,\"b_bypass\":%lld}",
648 f->GetLocalPath().c_str(),
f->GetFileSize(), f->GetBlockSize(),
649 f->GetNBlocks(),
f->GetNDownloadedBlocks(),
650 (unsigned long) f->GetAccessCnt(),
(long long) as->AttachTime, (long long) as->DetachTime,
651 f->GetRemoteLocations().c_str(),
652 as->BytesHit, as->BytesMissed,
as->BytesBypassed
654 setvbuf(stdout, NULL, _IONBF, 0);
655 bool suc = false;
656 ct++;
657
658 cout << "GSTREAM" << ct << endl;
And the test was to request a file using xrdcopy, receive the event (json)
on the collector (there is another counter here), send it to the rabbitmq,
and, read it from rabbitmq (count again).
