I correct the wrong name (It couldn't resolve from dns server), But now I have
this error:
0 Backend_health - boot.varnish_1 Still sick 4---X-R- 0 3 5 0.007800 0.000000
HTTP/1.1 400 Bad Request
My probe:
probe myprobe {
.request =
"HEAD / HTTP/1.1"
"Connection: close"
"User-Agent: Varnish Health Probe";
.timeout = 3s;
.interval = 5s;
.window = 5;
.threshold = 3;
}
Should I change the probe request "HEAD /" to something else?
Is there any way to define special port and whenever it is accessable even with
authentication erro (error 400) it consider backend healthy?

Subject: Varnish Health check
Hi,
I want to adjust health check on my varnish backends, But I dont know how can I
know they are healthy or not
because the nodes are up and running and even service is up but varnish does'nt
work for all requests (just third of them are responding till I restart it (It
happens sometimes)).
How can I check this?
```
backend server1 {
.host = "server1.example.com";
.probe = {
.request =
"HEAD / HTTP/1.1"
"Connection: close"
"User-Agent: Varnish Health Probe";
.timeout = 1s;
.interval = 5s;
.window = 5;
.threshold = 3;
}
}
```
