CirrostratusReverse Monitor and Pool Member Recovery
I have constructed a monitor to check a simple page and look for the string "up" in the response. Here's the sanitized definition:
ltm monitor http reverse {
defaults-from http
destination...
nitass
Employee
Employeethis is when it is not working. if i add one more char in the response, it starts working.
[root@iris:Active] config b monitor mymon list
monitor mymon {
defaults from http
reverse
recv "up"
send "GET /foo.html HTTP/1.1\r\nHost:\r\n\r\n"
}
[root@iris:Active] config curl -I http://10.10.70.110/foo.html
