How I can monitor ports on a server?

Thanks

I would use check_tcp: http://nagios-plugins.org/doc/man/check_tcp.html

In nagios XI

Return: conection refused

Who are the arguments?

COMMAND: /usr/local/nagios/libexec/check_tcp -H $HOSTADRESS$ -p $ARG1$ $ARG2$
OUTPUT: Connection refused

Thanks

All of the arguments are listed on the page I linked. For example, if you want to check port 2048 you would put that as ARG1.

COMMAND: /usr/local/nagios/libexec/check_tcp -H IP -p 80
OUTPUT: Connection refused

Are you sure that your host isn't broken?

Code: Select all

[jdalrymple@nagios libexec]$ ./check_tcp -H localhost -p 80
TCP OK - 0.001 second response time on port 80|time=0.001315s;;;0.000000;10.000000
[jdalrymple@nagios libexec]$ ./check_tcp -H localhost -p 81
Connection refused
[jdalrymple@nagios libexec]$ ./check_tcp -H 8.8.8.8 -p 80
CRITICAL - Socket timeout after 10 seconds
[jdalrymple@nagios libexec]$ ./check_tcp -H google.com -p 80
TCP OK - 0.020 second response time on port 80|time=0.020324s;;;0.000000;10.000000
