check_http: Invalid option - SSL is not available

[scheema31]

Hi,

i have recently migrated my nagios 4.0.8 from a rhel 5 server to a rhel 7 server, i have already migrated the conifgs and started nagios, service and host checks are being made.
however im having issues with the check_http command.
here is the command file:
define command{
command_name check_https
command_line /usr/local/nagios/libexec/check_http -S -H $ARG1$ -p 443 -u $ARG3$ --regex=$ARG2$ -w 8 -c 10 -t 15
}

what could i be missing here?

thanks,

How did you install Nagios on RHEL? I suspect the openssl-devel libraries were not installed when you compiled nagios plugins.

This guide explains how to install Nagios Core and Plugins along with all the required libraries like openssl-devel.

thanks for the reply box293,
from your guide you posted, i used the command to install the pre-requisite packages. however looks like i already have them:

[root@myserver01 ~]# yum install -y gcc glibc glibc-common wget unzip httpd php gd gd-devel
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
Package gcc-4.8.5-4.el7.x86_64 already installed and latest version

Nothing to do

You'll need to do the same for these packages:

Code: Select all

openssl openssl-devel

hey guys, i ended up installing the relevent packages and recompiled them on nagios:

yum install openssl-devel

wget http://www.nagios-plugins.org/download/ ... 1.1.tar.gz
tar zxvf nagios-plugins-2.1.1.tar.gz
cd nagios-plugins-2*
./configure --with-openssl --with-nagios-user=nagios --with-nagios-group=nagios
make all
make install

all good now! you may close this topic.
Thanks,

Glad to hear it is resolved. I am going to lock the thread. Please feel free to post again if you have you another issue. Thank you for using the Nagios forums!
