To improve HTTP-TPC transfer monitoring and for better transfer issue diagnosis WLCG BDT group proposed HTTP-TPC update which adds new Perf Marker
entries that provide real transfer connection source (Stripe Source
) and destination (Stripe Source
) addresses. The address format is same as defined for RemoteConnections
and it is composed of transport protocol, address and port separated by :
, e.g. tcp:192.0.2.100:1234
or tcp:[2001:db8::100]:1234
.
Example of whole performance marker with proposed extension:
Perf Marker\n
Timestamp: 1537788010\n
Stripe Index: 0\n
Stripe Bytes Transferred: 238745\n
Total Stripe Count: 1\n
RemoteConnections: tcp:147.231.25.166:21234,tcp:[2001:718:401:6017:2::28]:24081\n
Stripe Source: tcp:[2001:718:401:6017:2::28]:24081\n
Stripe Destination: tcp:[2001:1458:301:105::100:5]:8443\n
End\n
