notes_url doesn't work with hostgroup but works hostextinfo

We recently upgraded our Nagios 2.x installation to Nagios 3.2.x .
We used to provide `notes` and `notes_url` as part of the hostextinfo, like this:
Code: Select all
define hostextinfo{
host_name host1, host2, host3
notes These are special hosts
notes_url https://wiki.example.org/problemsolving/SpecialHosts
}
define hostgroup {
hostgroup_name specialhosts
alias Special Hosts
members host1, host2, host3
}
, so we want to get rid of it. Also, we would like to simplify the Nagios rules by consolidating the hostextinfo{} info into the hostgroup{} info, like this:
Code: Select all
define hostgroup {
hostgroup_name specialhosts
alias Special Hosts
members host1, host2, host3
notes These are special hosts
notes_url https://wiki.example.org/problemsolving/SpecialHosts
}
But if I use the hostextinfo{} definition above, the notes_url does work.
However, when we do this the notes_url does not appear in the CGI. Can anyone help me figure out why?

The notes are not displayed everywhere. As far as I know, you can only view them in the
Extended Information CGI.

In my case, the notes are not displayed either in extinfo.cgi or status.cgi.
In nagios 2, they were displayed in status.cgi and extinfo.cgi. It appears this should be the case in Nagios 3.2.3. Here is the sourcecode from status.c , which shows that notes_url should be called:
Code: Select all
if(temp_host->notes_url!=NULL){
printf("<TD align=center valign=center>");
printf("<A HREF='");
process_macros(temp_host->notes_url,&processed_string,0);
printf("%s",processed_string);
free(processed_string);
printf("' TARGET='%s'>",(notes_url_target==NULL)?"_blank":notes_url_target);
printf("<IMG SRC='%s%s' BORDER=0 WIDTH=%d HEIGHT=%d ALT='%s' TITLE='%s'>",url_images_path,NOTES_ICON,STATUS_ICON_WIDTH,STATUS_ICON_HEIGHT,"View Extra Host Notes","View Extra Host Notes");
printf("</A>");
printf("</TD>\n");
}
In addition, here's a screenshot from another user shows the "notes_url" icon (the red folder icon) from status.cgi :

I just tried this myself to refresh my memory on how this works, and I got the icon for notes_url in the list of services as well as the notes text displayed right in the service detail page. Did you restart Nagios after making the changes? If you're on 3.2.3 I don't really know what could be causing this.
