Unable to schedule downtime: error with Nagios Core

[combatzak]

We have recently started using NagiosXI, and I have encountered an error when attempting to schedule downtime for a host using the left navigation column Scheduled Downtime link.



Our environment details are as follows:

• OS Version: CentOS 7 64-bit
  NagiosXI version: 5.2.9
  Installation Type: Manual
  Special Configurations: SSL enabled

I found this thread which indicates that a nearly identical issue was fixed as early as version 5.2.3, however, we are using version 5.2.9 and encountering this problem.

I am able to confirm that I can successfully schedule downtime for a host through its host management page (using Nagios Core advanced settings). However even after scheduling downtime this way, the record's duration is incorrect. For example, a host scheduled for a 48-hour window shows a duration of 9h, 6m, 7s in the scheduled downtime page. I have confirmed that my account's date/time settings are set to use the standard YYYY-MM-DD HH:MM:SS format. This issue may or may not be related to the inability to schedule downtime described above.



Following advice from the above thread, I have included a tail of the /var/log/httpd/ssl_error_log file from the server (error_log was empty, likely because we are using SSL).

I appreciate any guidance or assistance with these issues.

Are you using HTTPS with a self-singed certificate?

Make sure that you have your shortname and FQDN in your /etc/hosts file on your XI server as well, this is usually the cause of it.

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

Thank you for the advice, updating the hosts file appears to have corrected the problem with being unable to schedule downtime. However, it appears that the duration for downtime records is still incorrect in some cases. Specifically, if I schedule a 48-hour downtime window for a host, the duration shown is 9h 6m 7s. This is a relatively minor problem as the downtime still seems to behave as expected, only the displayed duration is incorrect.

I was going to file a bug report, but the "9 hour duration" issue is already fixed in our development revision, so the fix will be in the upcoming Nagios XI 5.3.0.

[combatzak]

Sounds good. Thank you for your help. I will confirm the behavior is changed when 5.3.0 is released.

Since this is a known issue, is it alright if we lock this thread?
