Hi,
Exact process string is appearing in the ps output.
oracle 9882 1 0 May18 ? 00:01:40 ora_pmon_orcldb
Nagios: 2.7 on x86_64 (RHEL4)
Nagios plugins: 1.4.5
check_procs : (nagios-plugins 1.4.5) 1.54
NRPE: 2.6 (RHEL4)
Nagios server is on x86_64 and monitored server is an i386. And RPM
packages were built for the respective platforms.
Plugins were built as RPM packages on similar OS. Also there is only one
'ps' binary which is /bin/ps.
Regards,
Ajay

That explains why the process you want to monitor is called
ora_pmon_orcldb but not why check_procs can't detect it. That's likely
to be down to that exact string not appearing in the ps output that
check_procs is using, maybe due to truncation.
Back to basics. What version of Nagios are you using? What version of
the plugins? What version of nrpe? How did you compile/install the
plugins that are on the remote server, specifically were they compiled
either on that server or on a server running the same OS?

Hi,
I found the reason for the behaviour.
"Oracle have a process naming mechanism that enables you to distinguish
between multiple instances of the database. With Oracle, when you open
an instance, the $ORACLE_HOME/bin/oracle executable renames itself using
the UNIX environment variable ORACLE_SID for a given database. This
variable is used in generating Oracle process names:
ora_process_name_$ORACLE_SID."
So is there a away to monitor process (using the process name) as they
appear in 'ps -ef' output?
Regards,
Ajay

Subject: [Nagios-users] check_procs through nrpe gives wrong results
Hi,
I am monitoring a Redhat enterprise Linux 4 server running oracle using
Nagios and NRPE.
When I monitor Oracle PMON process (ora_pmon_orcldb) on the server I get
the message that 'PROCS CRITICAL: 0 processes with command name
'ora_pmon_orcldb''.
I have confirmed that process 'ora_pmon_orcldb' is actually running on
the remote server. The same type of monitoring works for other processes
such as 'httpd'.
Nagios command definition:
define command {
command_name nrpe_check_procs3
command_line $USER1$/check_nrpe -n -H $HOSTADDRESS$ -c
check_procs3 -a $ARG1$ $ARG2$ $ARG3$
}
NRPE configuration:
dont_blame_nrpe=1
command[check_procs3]=/usr/lib/nagios/plugins/check_procs -w $ARG1$ -c
$ARG2$ -C $ARG3$
>From the command line I see the following message:
[EMAIL PROTECTED] ~]$ /usr/lib64/nagios/plugins/check_nrpe -H
oracleserver -n -c check_procs3 -a 1:4 1:8 ora_pmon_orcldb
PROCS CRITICAL: 0 processes with command name 'ora_pmon_orcldb'
Any idea what is wrong?
Thanks,
Ajay
