NRPE: Unable to read output CentOS6

  • 772

I am monitoring a CentOS 6 machine with NTP service installed. The monitoring server is a CentOS 5 machine with Nagios and Centreon. I'm using NRPE for monitoring remote hosts, and I get the following error in two of four services that I configured:

NRPE: Unable to read output

I did check_nrpe -H (publicserverip) and everything seems to be OK. Also, I have configured the commands in nrpe.cfg

linux

    It's a permissions issue.

    Issue this command and you should be fine: chmod +x /usr/lib64/nagios/plugins/check_mem.

    In the future, ensure that all nagios plugins are executable.
