How to configure https_check URL in nagios

I have installed Nagios (Nagios® Core™ Version 4.2.2) in Linux Server.I have written a JIRA URL check using check_http for HTTPS url.

It should get a response 200, but It gives response HTTP CODE 302.

[demuc1dv48:/pkg/vdcrz/Nagios/libexec][orarz]# ./check_http -I xx.xx.xx  -u https://xxx.xxx.xxx.com/secure/Dashboard.jspa -S CONNECT
SSL Version: TLSv1
HTTP OK: HTTP/1.1 302 Found - 296 bytes in 0.134 second response time |time=0.134254s;;;0.000000 size=296B;;;

So I configured the same in the nagios configuration file.

define command{
        command_name    check_https_jira_prod
        command_line    $USER1$/check_http -I xxx.xxx.xxx.com  -u https://xxx.xxx.xxx.com/secure/Dashboard.jspa -S CONNECT -e 'HTTP/1.1 302'
}

Now my JIRA server is down, But it is not reflected in the nagios check.The nagios response still shows HTTP code 302 only.

How to fix this issue?

Solution

You did not specify, but I assume you defined your command in the Nagios central server commands.cfgconfiguration file, but you also need to define a service in services.cfg as services use commands to run scripts.

If you are running your check_httpcheck from a different server you also need to define it in the nrpe.cfg configuration file on that remote machine and then restart nrpe.

As a side note, from the output you've shared, I believe you're not using the flags that the check_http Nagios plugin supports correctly. From your post:

check_http -I xxx.xxx.xxx.com  -u https://xxx.xxx.xxx.com/secure/Dashboard.jspa -S CONNECT -e 'HTTP/1.1 302'

From ./check_http -h:

-I, --IP-address=ADDRESS
    IP address or name (use numeric address if possible to bypass DNS lookup).

You are using a host name instead (xxx.xxx.xxx.com )

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

You specified CONNECT
