Hey Guys, Problem: Monitoring Disk usage on remote machines. How I solved: wrote a wrapper plugin which will send command to remote host using nc (netcat). On remote host, configured xinetd to run a script which will read the command line sent by nc, parsed it and executed ./check_disk plugin. Question: Can the above problem be solved using check_by_ssh? If yes, i wish i can understand how nagios will send warning emails or critical emails? And if not the other option is nrpe... but then I will have to install nrpe on every remote machine! is that assumption correct? Dilemma!!!!!! help -- Gattu
