Nagios Support Forum

Greetings to All,

I am experiencing three issues with Nagios and I need assistance. First, I have a OpenSuSe box (10.217.99.101) that is failing to CGI script, even though the firewall is disabled and the Nagios configs are not detecting any errors. Error message:
Whoops!

Error: Could not read host and service status information!

The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you've just installed things, make sure you read the documentation on starting Nagios.

Some other things you should check in order to resolve this error include:

Check the Nagios log file for messages relating to startup or status data errors.
Always verify configuration options using the -v command-line option before starting or restarting Nagios!
Make sure you read the documentation on installing, configuring and running Nagios thoroughly before continuing. If all else fails, try sending a message to one of the mailing lists. More information can be found at http://www.nagios.org.


Second, NSClient++ is replicating the same exact error message on my Windows 7 (64 bit) workstation:
/server/protocol.hpp:65 Rejected connection from: ::ffff:10.217.99.100

Lastly, some menu selection, such as Map and Documentation, are not working due to object not found?

Object not found!

The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error.

If you think this is a server error, please contact the webmaster.

Things look okay - No serious problems were detected during the pre-flight check

Thank you in advance for your assistance to this urgent matter.

1) I see below that your configurations look good, lets make sure that nagios is actually running though. How have you installed nagios, package or source install?

2) Have you configured nsclient to receive from ipv6 addresses? It would appear that you are being rejected based on its internal IP whitelisting. You mentioned this is "the exact same error", is that just in reference to that it keeps saying the same thing?

3) what url are you attempting to check? Depending on, this could be similarly related to the first issue of the webui not working.

I installed the lastest version of Nagios Core (nagios-3.4.4.tar.gz) and Nagios Plugins (nagios-plugins-1.4.16.tar.gz), which is based on upgrading nagios core v3.2.3 and nagios plugins v1.4.16, from the following website:
(http://nagios.sourceforge.net/docs/3_0/ ... nsuse.html)



Answer 2)
I am running NSClient++ version 0.4.1.90 and I am only using IP version 4, not IP version 6. The reference are based on the same recurring NSClient++ log monitor.


Answer 3)
From the Nagios startup page, I am attempting to click on the url links: Documectation, Maps, Host, Process Info or Services; and it seems that the error message are completely non-responsive.
Error Message:
Whoops!

Error: Could not read host and service status information!

The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message.

While your configs seem to be fine, your nagios process does not appear to be running at all. You can either issue a service nagios start or /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg.

Again as for the whoops errors, lets get nagios running and see if they continue. I will address nsclient++ errors after as well, as right now nagios is not attempting to connect to it.

OK, I restarted Nagios serveral times and hard booted the system. Now it seems to be started.

Thanks for letting us know you got it working.

Thank you. How about the windows agent called NSClient ++?

What issue are you still running into with NSClient++?

Both xplaptop and c502 are windows machine. NSClient++ and Nagios are not fully retrieving the information. I review all documentation and it seems that I cannot find the nsc.ini file on both Windows XP and Windows 7, just nsclient.ini

NSC.ini and nsclient.ini are the same file, just a different name between versions. Which version of nsclient++ do you have installed? We recommend NSclient++ 3.9.x and not the latest versions as they are not fully bug tested yet.

Have you made sure that the windows firewall is allowing both port 12489 and 5666 through? 12489 is used for check_nt checks, and 5666 for NRPE checks. Also, be sure you allow this traffic on your Nagios Core server's firewall as well. I am assuming since you are using the default checks you will be using 12489 right now for configuration purposes.
