Hi,all
I configure the backend with one server and want to make the health
check for it using tcp.And the configuration as below.
backend httpservers
option tcp-check
This actually makes it perform tests on a higher layer: "Perform health
checks using tcp-check send/expect sequences"
If you remove the option tcp-check from the config it will probably do
layer4.
server server2 192.168.10.95:22 check inter 5s fall 1 maxconn 32000
But I find the log output below:
Sep 16 01:03:34 localhost haproxy[30429]: Health check for server
httpservers/server2 succeeded, reason: Layer7 check passed, code: 0,
info: "(tcp-check)", check duration: 0ms, status: 1/1 UP.
I could not understand why "Layer 7 check passed" for I think the
tcp-check only work for Layer 4.
Could you tell me more about this ?
Looking forward to your reply, thanks!
