Nagios Support Forum

hi..

My name is Satheesh Rajan, am in new in this field. Now am installed Nagios core 4.0.0 beta 1 in CentOS 6.3 .
Unfortuantely its showing "local host is down" with the message "(No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_load, ...) failed. errno is 2: No such file or directory " Can anyone help me..??? Actually am followed the steps thats shown in fedora quick start link.
Its selinux has been running on permissive state & iptables are disabled also.
What to do for this error and how to solve this issue..??? Advance thanks for your help..!!!

Well firstly, you should be using the Centos guide, since that is what you are using and not Fedora. What is showing this output? Where is it? Did you run through every, single, step in the guide?

hi..
First of all thanks for your support and reply.
In nagios quick start guides i saw only fedora,OpenSuse and Ubuntu guidelines . That why am followed the fedora quick start.
yes am ran every single and each steps that shows in the quick start guidelines.
I saw this error after am clicking on Hosts in the Left side panel. After click on the Host, shows the status of the local host is down also shows 8 services are in CRITICAL stage including http. All that services having the error as shown above.

Hope for your support
