RES: Nagios plugin problem using check_nrpe

[Antonio Fernando Evangelista]

Hi All,

I solved my problem including enabling the user nagios to execute the command /sbin/hpasmcli as root user.

Thank all of you.


Regards,

You're running the check as root, but NRPE executes checks as the nagios
user.

You'll probably be able to replicate the empty variables f you run:
[root at lnxaphmoa04 libexec]# sudo -H -u nagios
/usr/local/nagios/libexec/check_teste.pl -s4 -w80 -c85

The solution is:
1. Add permissions in sudoers for the nagios user to exec that script as
root without a password. The following line would allow the nagios user
to do passwordless sudo on any plugins:
nagios  ALL=(root) NOPASSWD:/usr/lcoal/nagios/libexec/

2. Change your nrpe.cfg to be:
command[check_teste]=/path/to/sudobinary
/usr/local/nagios/libexec/check_teste.pl -s 4 -w 80 -c 85

3. Restart npre
