HTTPS secured URL monitoring

[keerthiprashanths]

Hi Team,

We have a plugin (check_http) which is used for all URL monitoring but we are not able to implement any https:// check via the same.

We downloaded the https:// plugin from Nagios open source but still no luck.

Please help us on the same to monitor the https:// URL's via Nagios XI.

We downloaded the https:// plugin from Nagios open source but still no luck.

Can you share a link to the plugin you downloaded?

Can you also shed some light on what sort of problems you were encountering? The OP is a bit vague in that regard other than to say you are having trouble with https monitoring. That could mean the plugin usage, defining a service in Nagios XI to check a website via HTTPS, or anything in-between.

If you are using the "Website Monitoring" wizard, I believe there is a checkbox to use SSL.

The check_http help/man page offers the following argument for making SSL connections:

Code: Select all

     -S, --ssl=VERSION[+]
        Connect via SSL. Port defaults to 443. VERSION is optional, and prevents
        auto-negotiation (2 = SSLv2, 3 = SSLv3, 1 = TLSv1, 1.1 = TLSv1.1,
        1.2 = TLSv1.2). With a '+' suffix, newer versions are also accepted.

In action:

Code: Select all

$ check_http -H my.host.com
HTTP OK HTTP/1.1 200 OK - 332 bytes in 0.004 seconds |time=0.004144s;;;0.000000 size=332B;;;0

$ check_http -H my.host.com -S
HTTP OK HTTP/1.1 200 OK - 332 bytes in 0.004 seconds |time=0.004144s;;;0.000000 size=332B;;;0

I fully endorse @mcapra's response. Furthermore, I'd like to point you to https://assets.nagios.com/downloads/nag ... ios-XI.pdf

Also, check_http should be installed in XI. Is there a reason you downloaded it separately?

@mcapra :-

Link for https:// download :- https://exchange.nagios.org/directory/P ... ps/details

Basically we have configured a service in Nagios XI for HTTP monitoring by downloading the plugin from the Nagios open source.

Hope this clarifies your query.

Please let us know in case if any details are required.

Hi @keerthiprashanths,

Are you only trying to monitor your Nagios XI URL? with that check_https plugin?

I was able to use it, but on my Nagios XI I do not have SSL configured.

Could you post the command on how you are using this plugin?

[keerthiprashanths]

Please find the command attached with the screenshot.

According to the help for the plugin you stated you were using the command should be in this format

Code: Select all

/usr/local/nagios/libexec/check_https  mywebsite.com

You have a bunch of extra stuff in there, there shouldn't be -H flags, or -u flags, just the URL to check following the plugin path, and optionally a custom port following that

[keerthiprashanths]

Hello Team,

We tried that but it is the same issue.

- H represents the hostname

-u is mentioned for the URL.

I have attached the screenshot.

Please check and let us know what needs to be done now

@keerthiprashanths, And I assume that you can access this link from the web browser, right? Does the web page require any special authentication? Also, can you try to run the plugin with the same command but from the command line:
navigate to usr/local/nagios/libexec/

Code: Select all

./check_https ker-w-rsaapp01p.unity.media.corp/ssc/

You might get a more specific error info.
