How can i check https?

Posted: **Mon Jun 27, 2016 5:13 am**

You could use the standard check_http with the following option:

 -S, --ssl=VERSION
    Connect via SSL. Port defaults to 443. VERSION is optional, and prevents
    auto-negotiation (1 = TLSv1, 2 = SSLv2, 3 = SSLv3).

This must be the check_command definition at .cfg file

Code: Select all

check_command   check_http!S

When i run from command line:

Code: Select all

./check_http -H 195.130.109.104 -S -p 443

i am getting

Code: Select all

check_http: Invalid option - SSL is not available

What version of the plugin are you using?

Posted: **Mon Jun 27, 2016 11:46 am**

The latest i think. It installed with nagios plugins.

nagios-plugins-2.1.1.tar.gz was the file i downloaded

And what if you try this?

Code: Select all

./check_http -H www.google.com -S -p 443

[/s]

You need to recompile your plugins with SSL support. Use these steps, or similar.

Code: Select all

 cd nagios-plugins-2.1.1
./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-openssl
make
make install

yum install openssl-devel

and then re-install the nagios plugins

Code: Select all

./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-openssl
make

Code: Select all

Code: Select all
