Problem with Auto-Discovery

[ditlevw]

I'm currently doing some testing on this component/wizard. There was a bug in this component/wizard several weeks ago. There is phantom bug where the wheel will keep spinning and all you'll need to do is hit the refresh job list.

If you have some sort of IDS and packet sniffer that could be in issue as well, since fping and then the corresponding port check would definitely raise some IDS alarms.

I don't have any IDS ...yet.

Uh!

I just found another thread with a solution for my hosts that does'nt disapear when I remove them from CCM.

Thread: http://support.nagios.com/forum/viewtop ... osts#p9178
Solution: http://support.nagios.com/wiki/index.ph ... t_Hosts.29

I still got the initial problem with Auto Discovery though.

Aargh.

I just thought that things would start working after I found out how to delete hosts. Now my hosts (except localhost) have been deleted, but I can't add a new host!!! I run through the monitoring wizard and find my hosts, in this case network devices. It finds my hosts and I choose to add them, but they don't appear. Neither in CCM, "Host Detail" nor in "/usr/local/nagios/etc/hosts".

Why?

If the configuration applies but not changes take place, this is an indication of a permissions issue. Refer to our documentation on the topic:

Thanks, ...but it didn't help.

I checked the config in CCM and it returned with no errors (Things look okay - No serious problems were detected during the pre-flight check ). I restarted Nagios (from CCM) ...or at least I tried and it returned with this error: Restart failed - Nagios command file not found or no execute permissions. Then I executed the "reset_config_perms"-script in "/usr/local/nagiosxi/scripts" (not in "/usr/local/nagiosxi" as it says in the documentation). The script returned with:

Code: Select all

 ./reset_config_perms
SETUID ROOT OK
RESETTING PERMS

After that, I ran the test and tried to restart Nagios from CCM ...but with no success. I extended the test to try to add a host but now it seems even worse. When it gives me the option to assign it to hostgroups and servicegroups ...it doesn't show the groups. It's like if there aren't any. What the (sorry ) happened? Clicking "next" submits the configuration for processing then it runs the "Waiting for configuration verification......................................" for ages.

Well, then I did a:

Code: Select all

killall nagios
service nagios start

After that I accessed the Nagios Home and it returned with a permission error. It also told me what to do to resolve it. I ran the following commands:

Code: Select all

 chown root.nagios /usr/local/nagiosxi/scripts/reset_config_perms
 chmod u+s /usr/local/nagiosxi/scripts/reset_config_perms
 chown root.nagios /usr/local/nagiosxi/scripts/reset_config_perms.sh
 chmod u+s /usr/local/nagiosxi/scripts/reset_config_perms.sh

Then I tried to add a host again ...but same result as before. Killed the service and started Nagios again.

It's getting harder and harder for me to prepare a (working) demonstration of this product to my servicegroup. I have to find a product for monitoring more than 400 network devices and I'm running out of time.

Alright, we just developed a fix permissions script for this very case. Give this a shot. You'll need to download it to your linux server, chmod +x it and then execute it. You must be root when running it.

Hmm, ...Not sure if I've done it right, but take a look at this output:

Yeah, its ok if those perfdata files could not be found, and it looks like the plugins directory has the proper permissions. Are you now able to restart nagios?

Sorry. I ran out of patience. I deleted the NagiosXI from my ESX-environment and started all over again. While deleting the server from from the ESX, I discovered that someone had tried to install VMware tools. I must have been a mistake. I'm not sure if it has anything to do with it, but now I've installed NagiosXI again. Here is how I did it:

• Downloaded the latest NagiosXI release R1.6

• Converted vmx to fit my ESX, following your tutorial http://library.nagios.com/library/produ ... vmware-esx

• Started NagiosXI server and configured network settings with http://exchange.nagios.org/directory/Tu ... on/details

• Setup time to fit with my timezone - http://support.nagios.com/forum/viewtop ... f=6&t=2312

• Changed from trial-licens to FREE-license

Well, thats what I've done. Everything seems to be fine. I must also inform that the NagiosXI is behind a firewall but I all traffic from Nagios and back has been permitted. I can also inform that I have a switch on the same network segment as my NagiosXI and therefore doesn't need to pass through the firewall to access it.

I have tried to do an autodiscovery on both the segment I want to find all my network-devices on and on the same segment as the NagiosXI and the switch. It turns out with no result. Using the Monitoring Wizard finds the devices I want.

Should I try to run your script again? ... Thinking about doing it.

No no no. Not good.

I ran the script and the "XI System Component Status" turns red with the following errors:

Code: Select all

configuration file /usr/local/nagios/etc/nagios.cfg not found. Exiting

and

Code: Select all

configuration file /usr/local/nagios/etc/ndo2db.cfg not found. Exiting

I tried to reboot, but no change. Frustrating. Am I the only one with this problem?

When you click those gears that are next to the red exclamations, there should be a menu that shows up, allowing you to restart the service. Does it allow you to restart the services?

When the autodiscovery fails, how does it fail? Does it say no hosts found, or does it just spin forever?
