Can you give us an example of the full command? Do you know if the website uses chunked encoding?

Below is example
./check_http -S --ssl -c 15 -t 15 -f follow -H carrierlogistics.external.xerox.com -v
GET / HTTP/1.0
User-Agent: check_http/v2053 (nagios-plugins 1.4.13)
Connection: close
Host: carrierlogistics.external.xerox.com
HTTP CRITICAL - Error on receive
Not sure of the second part (chunked encoding).

Can you try using the -I switch instead of -H?

I get same output
./check_http -S --ssl -c 15 -t 15 -f follow -I carrierlogistics.external.xerox.com -v
GET / HTTP/1.0

Connection: close
HTTP CRITICAL - Error on receive
Even from other nagios server i receive same error.
./check_http -S --ssl -c 15 -t 15 -f follow -I carrierlogistics.external.xerox.com -v
GET / HTTP/1.0
User-Agent: check_http/v1991 (nagios-plugins 1.4.12)

I'm wondering if this is an IIS7 issue. I have the exact same things happening even if I add a user agent string or alter the timeout. Additionally, when loading via a web browser, it never finishes loading the page, I believe this may have something to do with the close statement you are getting from the server in check_http

Ravish, lets try this with the newest plugins build:
Code: Select all
cd /tmp
wget https://github.com/nagios-plugins/nagios-plugins/archive/master.zip
yum install -y unzip
unzip master
cd nagios-plugins-master/
tools/setup
./configure
make all
cd plugins
./check_http -S --ssl -c 15 -t 15 -f follow -I carrierlogistics.external.xerox.com
Did this check work?
EDIT, you should be able to just use -H as well:
Code: Select all
./check_http -S --ssl -c 15 -t 15 -f follow -H carrierlogistics.external.xerox.com

Note after abrists post, if it works you would need to move the new plugin to the libexec folder.
Code: Select all
mv /usr/local/nagios/libexec/check_http /usr/local/nagios/libexec/check_http.old
cp /tmp/nagios-plugins-master/plugins/check_http /usr/local/nagios/libexec/
All set to use without any changes to XI or your current commands!

It works with new plugin.
What is the difference between old and new.
