Hi,
The problem is fixed and the monitoring is enabled based on args in the
running process using ' -a ' option.
Defined the following in...
In commands definitions:
define command {
command_name nrpe_check_procs4
command_line $USER1$/check_nrpe -n -H $HOSTADDRESS$ -c
check_procs4 -a $ARG1$ $ARG2$ $ARG3$
}
In nrpe.cfg
command[check_procs4]=/usr/lib/nagios/plugins/check_procs -w $ARG1$ -c
$ARG2$ -a $ARG3$
Checking via command line:
/usr/lib64/nagios/plugins/check_nrpe -n -H ORACLESERVER -c check_procs4
-a 1:4 1:8 ora_pmon_orcldb
Regards,
Ajay

The exact process string is appearing with the options you are
giving to ps. However Nagios may be using different options or even a
binary it builds itself.
You can find out by grepping PS_COMMAND in config.h in the
plugins build directory.
On Fedora Core 4, that gives:
#define PS_COMMAND "/bin/ps axwo 'stat uid pid ppid vsz rss pcpu
comm args'"
On Solaris, it gives:
#define PS_COMMAND "/usr/local/nagios/libexec/pst3"

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

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
