Host performance graph: missing image

[rks]

I am trying to 15 linux servers with Nagios XI. I get the correct host performance graphs
for 8 of them and the localhost. I get a "question mark" image for 7 of the servers (
as shown in attached). Why does this happen? All configuration was done thru the GUI.

thanks,

Can you run the following immediately after trying to access a page with the question marks:

Code: Select all

tail -20 /var/log/httpd/error_log

Also, can you see any text returned when mousing over the question marks? If so, what is it?

Code: Select all

[root@ctvmanager ~]# tail -20 /var/log/httpd/error_log

Can you take a look at this post and see if it applies to your setup?:

http://serverfault.com/questions/425808 ... -interface

Do you have SSL enabled with Nagios XI?

Additionally, lets fix that module.so problem,

Code: Select all

vi /etc/php.d/mcrypt.ini

Verify that the extension is:

Code: Select all

extension=mcrypt.so

If it is not, change it, then restart apache for good measure:

Code: Select all

service httpd restart
