Hi all, I have this weird trouble with getting nrpe agents work. My nagios server hosts on Debian box while agents on Debian and Centos (all installed from official binary packages) and the problem is check_nrpe always returns this "NRPE: No output returned from plugin" error when I check NRPE on any Centos host and this is true with all plugins - all of them does not return anything. I turned on debug at one Centos host but still it does not show me anything, when I run from nagios host:
./check_nrpe -H centos.host.com -c check_load I always get "NRPE: Unable to read output" and there is nothing in syslog at agent's host in spite of debug is on. My assumption was that command definitions on Centos host side use path to plugins that is different from Debian, for example: command[check_load]="/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20" [Debian host] command[check_load]="/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20" [Centos host] but I made symbolic link so that plugins could be called by the same path - it didn't help. When I run command locally, all works just fine: su nrpe -c "/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20" OK - load average: 1.28, 0.97, 0.97|load1=1.280;15.000;30.000;0; load5=0.970;10.000;25.000;0; load15=0.970;5.000;20.000;0; while from nagios server: ./check_nrpe -H centos.host.com -c check_load NRPE: Unable to read output The weird part of it is that all plugins work fine on debian hosts. Nagios uses the same host, service and command definitions for all monitored hosts (both debian and centos) and I really wonder what's wrong with centos nrpe agents :/ If anyone have any ideas, please try to help. P.S. I use Nagios server v.3 (from Debian lenny) and Nrpe agents versions are the same on Debian and Centos (v.2.12). -- best regards, Yuris Linux System Engineer, SMTP.com ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
