On the remote host, run the following:

Code: Select all

su nagios
/usr/local/nagios/libexec/check_services -p sendmail
sudo /usr/local/nagios/libexec/check_init_service syslog

What do you get?

The error is the same for sendmail, however there is no response for syslog

Code: Select all

[nagios@localhost root]$ /usr/local/nagios/libexec/check_services -p sendmail
  *** sendmail: Nok ***
[nagios@localhost root]$ sudo /usr/local/nagios/libexec/check_init_service syslog

does this client have syslog installed? or is it rsyslog?

Code: Select all

ls /etc/init.d/|grep syslog

The error is the same for sendmail

Code: Select all

[nagios@localhost root]$ /usr/local/nagios/libexec/check_services -p sendmail
      *** sendmail: Nok ***

In my opinion, the sendmail service on that server is not running, the check_services is reporting this (which is good).
Here's an example using crond:

Code: Select all

[root@centos01 ~]# service crond status
crond (pid  1054) is running...
[root@centos01 ~]# su nagios
[nagios@centos01 root]$ /usr/local/nagios/libexec/check_services -p crond
  crond: 1
[nagios@centos01 root]$ exit
[root@centos01 ~]# service crond stop
Stopping crond:                                            [  OK  ]
[root@centos01 ~]# su nagios
[nagios@centos01 root]$ /usr/local/nagios/libexec/check_services -p crond
  *** crond: Nok ***

does this client have syslog installed? or is it rsyslog?

Code: Select all

ls /etc/init.d/|grep syslog

Hi, it is a rsyslog.

Code: Select all

[root@localhost ~]# ls /etc/init.d/|grep syslog
rsyslog

I changed the command for 'syslog' to 'rsyslog' and its working now! Thanks heaps!
check_nrpe!check_init_service!-a 'rsyslog'
