Hi all, I've installed check_nt and check_traffic on a RH9.0 linux box. My 2 problems are, I think, simple : 1 - where can i download the list of the Microsoft Counters, for performing monitoring on WNT4.0, W2K and WXP machines ? All of my machines are setup with French OS. So, when i will have it, i must declare all of them in the counters.defs file, I mean ? Reply will be appreciate 2 - I've setup check_traffic. On command line, all is good. But when I click on traffic con, I get "500 - Internal Server Error " and in the apache error_log file, there is an entry : "check http://myserver/nagios/main.html". Can anyone help? Thanks, regards, Frank
