2nd nrdp/nagios server not able to change web page status

Posted: Sat Dec 02, 2017 10:47 pm

I googled and look at your knowlege db article regarding nrdp keyword and struggle for some time hope you give me a pointer where I did wrong on 2nd nrdp server's setup.

I have two nagios server(nagios01 and nagios03) each running on centos 7.4.
nagios01 is primary active and nagios03 secondary active but with notification disabled.
nagios01 is running nagios 4.1.1 rpm I packaged while nagios03 is running rpm package directly from Fedora repository.
The configuration paths in nagios.cfg is different between 4.1.1 and 4.3.2.

nagios01 have nrdp 1.4.0 configured correctly and passing send_nrdp.sh check and it is receiving forwarded status/alert from another nagios 3 server(nagios05) running on ubuntu 16.04.

My problem:

I like to have nagios03 receive nagios05's forwarded alert/status correctly. But my problem is that I can run send_nrdp.sh to send a test message with 2(red) status, meaning login from client to nrdp server is ok. but the nagios03 web page won't turn red like nagios01 does.

following command was able to trigger a red alert on nagios01 but not nagios03

Code: Select all

[me@nagios03 ~]$ /usr/local/bin/send_nrdp.sh -u https://nagios03.test.com/nrdp -t nagios_secure_token -H esxi05r.test.com  -S 2 -s check_dummy  -U nrdp:password+1234

/usr/local/bin/send_nrdp.sh -u https://nagios03.test.com/nrdp -t nagios_secure_token -H esxi05r.test.com -S 2 -s check_dummy -U nrdp:password+1234
I don't see an option for -U? Is that something you added?

Code: Select all

Usage: send_nrdp.sh -u URL -t token [options]

Usage: send_nrdp.sh -h display help


This script is used to send NRPD data to a Nagios server

Required:
    -u,    URL of NRDP server.  Usually http://<IP_ADDRESS>/nrdp/
    -t,    Shared token.  Must be the same token set in NRDP Server

Options:
    Single Check:
        -H    host name
        -s    service name
        -S    State
        -o     output

    STDIN:
        [-d    delimiter] (default -d "\t")
If the NRDP check sent 1 test check, it should be logged in --> /var/log/messages

Here's my example when I use send_nrdp.sh

Code: Select all

/usr/local/nrdp/clients/send_nrdp.sh -u http://192.168.4.125/nrdp/ -t WXsWrqTQjl65 -H localhost -S 2 -s check_http123
Sent 1 checks to http://192.168.4.125/nrdp/
In var/log/messages, I see this.

Let us know if you are able to see the check in the logs.

Hi Kyang

Thanks for working on my case.

>I don't see an option for -U? Is that something you added?
Yes.
I added -U since my nagios server has access limitation with ldap server and local group/user from htpasswd.users and htgroup.users two files.
nrdp user is local user reside in both ht files.

Code: Select all

[me@nagios03 nagios]$ grep nrdp ht*
htgroup.users:localgroup: winadm nagiosadmin nrdp
htpasswd.users:nrdp:$apr1$xxxxxyji1
[me@nagios03 nagios]$
localgroup is defined in /etc/httpd/conf.d/nagios.conf also

I am interested to make my nagios03 using supported nrdp server/client version.
Following quick tests using stock version of send_ndrp.sh and my customized one to work with my nagios servers.
I don't see the nrdp traffic log in /var/adm/messages at all.
