I am using DR and using an external program to check whether a server is
alive or not:
send_program = "/root/chknanny.sh %h"
expect = "SERVER_OK"
load_monitor = none
scheduler = wlc
protocol = tcp
timeout = 10
reentry = 10
This is the chknanny.sh script:
lynx -dump "http://$1/TestServer.ashx"
Which should return SERVER_OK . If it does not or it times out the server
should be removed from the pool.
I'm having a situation where lynx does not return SERVER_OK but the timeout
value of 10 seems to have no effect. The server still remains in the
server pool which is stranges cause messages log file report this:
Nov 26 01:34:13 dell-LB1 nanny: Ran the external sending program to (
10.0.1.108:80) but didn't get anything back
