I deleted and rewrote the config files an...

how can I find out if a server rebooted if I only ping monitor a server?

I figured it out.

I configured one like that and it worked. I copied that check out to all servers and about half are failing with this error "External command error: snmpget: Unknown user name (Sub-id not found: (top) -> sysUpTime)"

I just downloaded the Nagiosxi demo. I am trying to monitor a Linux disk using snmp. I am monitoring a few drive that report correctly. however I have one disk that is 10TB. the monitor reports that I am using 5TB out of 2TB, or %253. check_xi_service_snmp_linux_storage! --login=***** --passwd=*****...
