Thanks Graeme, for the reply.
Here's my result:
1) ipvsadm -Ln --stats
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Conns InPkts OutPkts InBytes
OutBytes
-> RemoteAddress:Port
TCP VIP1:80 1207524 12718506 0 2502M 0
-> RIP1-2:80 48784 456988 0 68388231 0
-> RIP1-1:80 719206 7807994 0 1451M 0
TCP VIP2:80 2631485 27031952 0 5674M 0
-> RIP2-2:80 1082721 10626928 0 2422M 0
-> 1RIP2-1:80 1548764 16405024 0 3251M 0
2) ipvsadm -Ln --rate
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port CPS InPPS OutPPS InBPS
OutBPS
-> RemoteAddress:Port
TCP VIP1:80 3 28 0 5768 0
-> RIP1-2:80 0 0 0 0 0
-> RIP1-1:80 3 28 0 5768 0
TCP VIP2:80 7 71 0 18218 0
-> RIP2-2:80 0 0 0 0 0
-> RIP2-1:80 7 71 0 18218 0
Questions:
-- in "--stats" command output, the number 68388231 doesn't make any sense
to me, what's it?
-- the statistical info is reset on each restart, is it true? if it is true,
the load seems not balance (I am using the lc scheduler). Why?
-- What are those numbers representing in the "--rate" command output? I am
seeing all 0 for the remote server, why?
Thanks,
Yan
