Nagios Support Forum

Hello

I have some issues after migration,
Old Server: Centos 5_32bit
New Server: Centos 7_64bit
Centos Version 5.2.9
Same Name, Same IP. Iptables & Firewall Disabled. On the same network with other Servers.

I. I first followed the steps provided on this page
https://assets.nagios.com/downloads/nag ... ios-XI.pdf
and it was successful, All Hosts and services are already connecting tho there few issues but I have created that particular issue at another post.

II. After the migration and installation of plugins, I then converted the RRD's for the Performance Graph and It's also working.

III. I am now testing the notifications / acknowledgements / email notifications to make sure it's working and these are the issues
These are all from the Webpage:
1. 'Acknowledge this problem' isn't working
:: I can click on the Acknowledge this problem, but there is no output, the Acknowledge Problem box appears but nothing changes when clicking the Submit

2. Email notifications are not working
:: Postfix is enabled and I tried sending an email via CMD line to my companyemail, im able to receive it, enable_notifications=1 is set on nagios.cfg file. I tried testing sending an email from the Webpage using the Manage Email Settings > Send a Test Email and it is Failed.
Email is working on the Old Server..

Thank you

I'd like to work on one problem at a time to make it less confusing. That way we aren't sending each other two different questions and answers. Or you could create another thread for the notification issue that way it is separate.

For the acknowledgment problem, could you try to acknowledge again through the UI a few times and then send us your profile so we could see the logs?

Nagios XI Profile --> On the XI Home Page click "Admin" > "System Profile" --> "Download Profile" button
Save the profile.zip file and upload it here or PM me.

If you receive a PROFILE BUILD FAILED
Please follow this article,

After you PM the profile please update this thread, unless you post the profile on here. Thanks

Edit: PM received!

Hi Kyang,

I sent you a private message, for the acknowledgement, I just noticed that it only happens on some servers, is there a way to remove the acknowledgement?

You can remove an acknowledgment by going to that host/service to get the status detail page--> click on the + sign that says advanced --> under commands you should see something that says "Remove Acknowledgement".

So acknowledgments work on some and do not work on others?

I do see a lot of these apache error_logs. Are you using HTTPS?

Make sure that you have your shortname and FQDN in your /etc/hosts file on your XI server as well.

Validate the URL in Admin > System Settings > Program URL and External URL.

Hi Kyang,

Thank you for the response, I'm using http only.
Should the Program URL and External URL be the same? That's how it was set before on the old server so I'm assuming they would still work.

Yes, some work, and some not. like for this example, so I tried to remove the acknowledgement, and it was removed but, there is still an icon that it was acknowledged. I have added the shortname and FQDN on the /etc/hosts file..

I don't have it set up, but normally an external URL is listed as this.

The URL used to access Nagios XI from outside of your internal network

Were there any issues with having the same URL? Back to the acknowledgment issue,

When you tried to remove the acknowledgment, were there any different apache error logs?

Could you try it again, and then send us some logs?
Additionally, could you send us the output of these commands also?

Hi Kyang,

Here you go for the last part:

I sent you a private message

Thanks, I received the error_logs and shared with my team.

Could you try running each from the command and see if that fixes the acknowledgment issue?'
Once finished, try acknowledging and see if that works?

If not post the output of these.
UPDATE: Logs received

Hi Kyang,

I did try that, and even rebooted the server. I sent you a PM for the logs

Thanks for the logs,

When you try to acknowledge something now, what happens? Is it the same?

Try it again, and PM me your access_log and error_logs.
I'd like to get updated apache logs to see what happens when you do it, as it should be logged.
