Hello,
Zen support check_http, which is basically a nagios plugin. So far, so
good, documentation here:
http://www.zenloadbalancer.com/farmguardian-quick-start/
This tutorial is somehow wrong.
When testing farms servers, you want to connect to its IP to test a
specific one node, but you need to provide the true site you are load
balancing through host header.
check_http help:
check_http *-H <vhost> | -I <IP-address>* [-u <uri>] [-p <port>]
[-w <warn time>] [-c <critical time>] [-t <timeout>] [-L] [-a auth]
[-b proxy_auth] [-f <ok|warning|critcal|follow|sticky|stickyport>]
[-e <expect>] [-s string] [-l] [-r <regex> | -R <case-insensitive
regex>]
[-P string] [-m <min_pg_size>:<max_pg_size>] [-4|-6] [-N] [-M <age>]
[-A string] [-k string] [-S] [--sni] [-C <age>] [-T <content-type>]
[-j method]
So the correct way should be:
check_http -w 9 -c 9 -H VHOST -I HOST -u / -p PORT
HOST constant in Zen equal IP address of web server, so argument is
-I.Tutorial is using -H, which is to specificy a Virtual HOST header.
Providing IP address for all sites is quite useless....
So I am missing a critical constant: VHOST (or something matching virtual
host).
>From quick start there are only 2 constants: HOST and PORT.
Did anyone manage to workaround that ?
