Nagios Core Update Available Banner Not Displayed

Posted: Thu Dec 05, 2013 4:14 pm

When I visit my Nagios Home page (main.php) a blue banner should be displayed showing that an update is available IF I am behind on my Nagios updates. That banner is not displayed for me. Here is the head of my Nagios status.dat file:
info {
created=1386277022
version=3.5.1
last_update_check=1386260857
update_available=1
last_version=3.5.1
new_version=4.0.2
}
After playing with the main.php code, I found that the variable "update_available" reads as blank when read in the php page. Since php sees that variable as blank, it never passes the "else if" check, so it never displays the banner.

Can someone answer me on this? At least tell me if it's happening to them too?

Can you run the following, open the home page, and show us the output from the CLI after the page has loaded?:

Code: Select all

tail -f /var/log/httpd/error_log
If you are running a distro other than RHEL or CENTOS the apache error log may be elsewhere.

Nothing was displayed in the error_log at all. The access_log did show me hitting the home page (main.php & side.php).

P.S., right now I am up-to-date (Nagios Core v4.0.2), so it shouldn't show the update available banner.
I could clone one of my Nagios servers and put an older version of Nagios on it if that would be helpful? If so, do you care what version I install?

Stick with older versions of 4 (4.0 or 4.0.1) as 3.5.x will probably not see much dev time.

I cloned one of my Nagios Core v4.0.2 servers, and we back to v4.0.1. When I hit the home page now, I see the following two entries each time in the apache2/error_log:

[Fri Jan 17 15:43:43 2014] [error] [client 10.101.40.40] PHP Warning: MagpieRSS: Failed to fetch http://www.nagios.org/backend/feeds/frontpage/ and cache is off in /opt/nagios/share/includes/rss/rss_fetch.inc on line 238, referer: http://nag5.leoncountyfl.gov/nagios/main.php
[Fri Jan 17 15:43:48 2014] [error] [client 10.101.40.40] PHP Warning: MagpieRSS: Failed to fetch http://www.nagios.org/backend/feeds/corepromo and cache is off in /opt/nagios/share/includes/rss/rss_fetch.inc on line 238, referer: http://nag5.leoncountyfl.gov/nagios/main.php

...but I don't think this has anything to do with the update check.

The update check only happens daily, but being you are getting these errors, and those pages do exist, leads me to believe you may be behind a proxy that isn't setup properly on this machine.

From the CLI, do you get output when running

Code: Select all

curl "http://www.nagios.org/checkforupdates/?version=4.0.1&product=nagioscore"

I ran the curl command and it displayed a long response. I don't think you really want me to post that, but it's the code from the update check web page.

I went back and looked at the error_log while accessing the home page and it is still empty, but the access_log is showing more entries. Here is the tail from that log:

Well we would ideally like to see the output from curl. Can you wrap all code/output in code wraps? This contains it in a box, and is quite a bit easier to read. I used your post above as an example for you.
