NimbostratusConfiguring Monitors on F5 LTM
I am fairly new to F5 and trying to set monitors for my SharePoint farm , I tried creating HTTP monitor , its just basic HTML file with "Up" text in it ... What I am trying to achieve is , if I change this text from "Up" to "Down" it should take that node out of Load Balancer Pool , and converting it to "Up" again should put that node back in Load Balancer pool. Below is my Send and Receive strings :
Send String : GET /http://server:port/_layouts/images/filename.html HTTP/1.1\r\n Receive String : Up
As soon as I apply this Receive String , both nodes goes down ... If I keep Receive String as "OK" or blank it works fine but that's not solving my purpose. Please let me know what's wrong here , Is there any other way to achieve this. Pardon me if its very basic thing to do ... Thanks
Ah, the host header is required by most web-servers. We'll try again:
telnet 10.10.10.1 80 Then type GET /_layouts/images/filename.html HTTP/1.1 Enter once HOST: server domain Enter twice
ArtRst_137283Wow ... Thanks a lot Thomas , That worked .. I put "Down" in Receive Disable String , and change send string as you suggested ... and its all working as expected.... I am sure it was very simple monitor to configure (Not for me though) ... but my next task will be little more complicated ... basically I am trying to configure monitors for IIS level .. so it should enable or disable Pool member if Application Pool / IIS site goes down and also if there is any interruption on specified windows service. I got this article and it sounds the same that I am trying to do.... Please let me know if there is any other link that I can refer..... Thanks Thomas and F5Help.

Hi ArtRst Thoman, URGENT early response will be appreciated. if you are still on then can you tell me what you have done exactly to make it work. I am using iApp to configure. I have two node (servers) 10.160.0.106 & 10.160.0.107.
I am able to telnet on port 7002 and working okay. and also both servers returning response for below command from CLI.
GET http://10.160.0.106:7002/oncfo/index.html curl -v http://10.160.0.106:7002/oncfo/index.html
however when I do tcpdump and surprised to see that there is no response of default monitor GET command.
monitor string looks like below. GET /oncfo/index.html
but when I tried from CLI, the below output in tcpdump. GET /oncfo/index.html HTTP/1.1
User-Agent: curl/7.19.7 (i686-redhat-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8u zlib/1.2.3 libidn/0.6.5
Host: 10.160.0.107:7002
Accept: /
however the Pool is still down due to Monitor.
