tac.cgi query parameter ?

[emi65]

Hi
I'm using nagios core 4.4.5

I like to know if exit a way to query the tag.cgi page

http://nagios.intranet.servizi/nagios/cgi-bin/tac.cgi

in the same way like this
http://nagios.intranet.servizi/nagios/c ... _Check_CPU

Are there parameter to get the total number of hosts down or services Critical ?

thanks for the help
Emilio
