Hi all,
sorry if this is a dumb question, I just joined here...
My problem is that I am not able to view any trend graph in Nagios 3.0. I run a
self-compiled package on Ubuntu 7.10/amd64.
I configured cgi.cfg as follows:
<snip>
use_authentication=1
authorized_for_system_information=*
authorized_for_configuration_information=*
authorized_for_system_commands=*
authorized_for_all_services=*
authorized_for_all_hosts=*
authorized_for_all_service_commands=*
authorized_for_all_host_commands=*
</snip>
Allowed users are authenticated by Apache, so this should be fine for my
environment.
With this setup, I can view *anything* in the Reporting section, i.e.
Availibilities, Alert Histogram, History and Summary, Notifications and Event
log, *except* for Trends. The first two steps work, but finally I just get
It appears as though you are not authorized to view information for the
specified host...
The same happens e.g. when viewing the availability report for a single host.
The tables are produces, but instead of the graph only "[Broken image icon] Host
state trends" is shown.
Running trends.cgi in gdb, it apparently fails at this point:
<snip>
~ printf("</table>\n");
~ }
#ifndef DEBUG
~ /* check authorization... */
~ if(display_type==DISPLAY_HOST_TRENDS){
~ temp_host=find_host(host_name); // fail here!!!
<snip>
because the call to find_host() returns NULL. Again, running the other scripts
from the command line, with the same host entry, *does* work fine.
Any idea what I did wrong here?
Thanks in advance,
Albrecht.
