Most are just generic checks, like NSClient version, Uptime, Drive Space, Memory Usage, several processes and services, etc. It's a Windows 2000 server host running the NSClient++. It's hard to catch this while it's happening because it only lasts a few minutes and I'm never here when it happens.
I started slowly transitioning from using check_nt to check_nrpe and the responses vary between the two: check_nt reports: No data was received from host! check_nrpe reports: Socket timeout after 10 seconds. I don't believe it's a network connectivity problem, or the ping check wouldn't succeed and the other checks wouldn't run. I guess it could be a non-responsive system condition, perhaps some process hogs all CPU cycles or something like that...

Nagios is alerting you to a general problem. Without knowing specifics about what you're checking and how, generally speaking the host was unreachable, down (if this is a check_snmp check), too busy to respond or otherwise non-responsive. You should investigate as the problem is almost certainly real. Maybe you have a network connectivity issue or problem on those hosts. -- Marc ------------------------------------------------------------------------ ------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
