Re: [Nagios-users] check_procs through nrpe gives wrong results
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

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.
oracle9882 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.

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?

Re: [Nagios-users] Problem: Perfmon counter gives wrong results w hile using check_nt
Dear All: I am using pnsclient on Windows servers as Nagios agent. Any Solution for this problem? Regards, Ajay -Original Message- From: Anthony Montibello [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 06, 2006 9:38 PM To: nagios-users@lists.sourceforge.net Cc: M V Ajay (vMoksha) Subject: Re: [Nagios-users] Problem: Perfmon counter gives wrong results while using check_nt Hi, If your windows agent is NC_NEt, I know the reason why, It has to do with delay between taking samples of the performance counter object before reporting it to back to check_nt To elaborate, most Performance monitor objects in windows takes a sample every one second then return the caalculated results to Performance monitor for graphing. NC_NEt does not wait a full second for this to happen, and in the current inplementation it is actually too quick between samples and thus gives a result of 0. I have experimented with different delay times (in Miliseconds) and found a good speed/accuraccy compromise that I will implement as adjustable variable in the configuration of the next release of NC_NEt. Note: NC_NEt would report a -1 if the it could not locate the counter because of an error or spelling. but a 0 means really 0 or the above mentioned bug. Just to defend NC_NEt. in the past, this bug slipped through due to the Performance counter documentation of Dot NEt specifying just to call the get sample function again, and the documentation failed to mention any standards as to a minimum delay between requests. Also most of NC_NEt testing in the past has been done offline of Nagios. I am about to install nagios for testing, and hopefully would have that running by the time I get the updates into NC_Net. As a workaround you may be able to retrieve the value you need through WMI or by creating a custom performance counter that is of a different type but gets its value from the one that is mis-informing NC_NEt. NC_NEt is availible at sourceforge: http://sourceforge.net/projects/nc-net http://sourceforge.net/projects/nc-net If it was a different Windows Client then I do not know the source of the reason but next generation of NC_Net should work more efficiently.
