[Fwd: All hosts status undetermined in reports]

[Andy Shellam]

Hi Marc,

I've got a hold of this and a fix now.

In the availability report, if you selected a host or service group,  
it passed the host/group chosen in step 2 over in the URL to step 3  
as, for example, Telecity+Router+1 - which is correct.

However, it then URL encoded the value back to the HTML source of step  
3 - e.g.
<input type='hidden' name='host' value='Telecity+Router+1'>.

However when you submit this form, the browser then converts the +  
characters into %2B's - e.g. Telecity%2BRouter%2B1.  Nagios then  
interpets the host as Telecity+Router+1, which obviously doesn't exist.

It's a simple fix, thankfully!  Unfortunately I don't know how to  
create diff patches, so I can only tell you what to change:

In avail.cgi, line 650:

from:

printf("<input type='hidden' name='host'  
value='%s'>\n",url_encode(host_name));

to:

printf("<input type='hidden' name='host' value='%s'>\n",host_name);

In avail.cgi, line 654:

from:

printf("<input type='hidden' name='servicegroup'  
value='%s'>\n",url_encode(servicegroup_name));

to:

printf("<input type='hidden' name='servicegroup'  
value='%s'>\n",servicegroup_name);

Note that host groups and services didn't suffer this problem - just  
hosts and service groups!

Can this fix make into 3.0.3?

Thanks,

Andy
