Nagios Support Forum

Hi,

We want to monitor AWS server (1 Windows 2012 and 1 Linux) from Nagios tool.
we have also enabled firewall to access these servers over 5666,161 and 12498 ports and we have also installed NS client in both the remote servers.

Now when we configure both the servers in Nagios, we are successfully able to monitor ping service, however for other services like CPU Utilization, memory and disk we get
Linux Error: CHECK_NRPE Recieved 0 bytes from daemon, check the remote server logs for error message
Windows Error: NS Client ERROR: could not complete the request check log files for more information

However there is no error log generated in the remote servers.


Also when we try to monitor these servers using SNMP we are successfully able to monitor ping service, however for other services like CPU Utilization, memory and disk we get
Linux Error: ERROR: Description/Type table : No response from remote host 'XX.XX.XX'.
Windows Error: ERROR: Description table : No response from remote host 'XX.XX.XX'.

Please let me know if anyone has faced this issue before or can provide me a solution for this

Has SNMP been properly set up on the systems? You need to do this, in addition to opening the default ports on which their data travels. Also, I noticed that you said you opened port "12498" on the windows system, this needs to be changed to "12489" or the port you specified in the NSClient.ini file.
