Hi Natxo, First, thank you for your time. Here is my nrpe.conf : _________________________________________________________________________________________________ log_facility=daemon pid_file=/var/run/nrpe.pid server_port=5666 nrpe_user=nagios nrpe_group=nagios dont_blame_nrpe=0 debug=1 command_timeout=60 connection_timeout=300 command[check_users]=/usr/local/nagios/libexec/check_users -w 10 -c 15 command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20 command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/mapper/VolGroup00-LogVol00 command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 655 -c 700 command[check_jmx]=/usr/local/nagios/libexec/check_jmx -U service:jmx:rmi:///jndi/rmi://localhost:8999/jmxrmi -O java.lang:type=Memory -A HeapMemoryUsage -K used -I HeapMemoryUsage -J used -vvvv -w 800000000 -c 1500000000 _________________________________________________________________________________________________ all my commands are working except the check_jmx. Nrpe is running through xinetd, here is my nrpe file in /etc/xinetd.d : service nrpe { flags = REUSE socket_type = stream port = 5666 wait = no user = nagios group = nagios server = /usr/local/nagios/bin/nrpe server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd log_on_failure += USERID disable = no only_from = 10.1.2.1 127.0.0.1 10.1.2.200 } Regards, emmanuel <div class="gmail_quote">2010/4/13 Natxo Asenjo <<a href="mailto:natxo.asenjo@gmail.com">natxo.asenjo@gmail.com</a>> <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div class="im">On Tue, Apr 13, 2010 at 8:39 AM, Emmanuel Chanteloup <<a href="mailto:manuchanteloup@gmail.com">manuchanteloup@gmail.com</a>> wrote: > The thing I do not understand is why I can run it directly with my nagios > account : > > [nagios@myserver ~]$ /usr/local/nagios/libexec/check_jmx -U > service:jmx:rmi:///jndi/rmi://localhost:8999/jmxrmi -O java.lang:type=Memory > -A HeapMemoryUsage -K used -I HeapMemoryUsage -J used -vvvv -w 800000000 -c > 1500000000 > JMX OK > HeapMemoryUsage.used=593227424{committed=1036189696;init=1073741824;max=1036189696;used=593227424} > > and it doesn't work with NRPE, knowing that NRPE is using the nagios account > ! > > [nagios@myserver ~]$ /usr/local/nagios/libexec/check_nrpe -H localhost -c > check_jmx > NRPE: Unable to read output </div>could you please post your nrpe.cfg (sanitize as needed) to make sure there is not a typo in it? (I've had that many times myself, very frustrating). Another option worth exploring is <a href="http://search.cpan.org/%7Eroland/jmx4perl-0.65/scripts/check_jmx4perl" target="_blank">http://search.cpan.org/~roland/jmx4perl-0.65/scripts/check_jmx4perl</a>. Another thing: I am not sure how nrpe escapes the slashes (if at all) in the uri in that check. Try adding more on slash in front of every other slash. Just a wild shot, I know. -- <div><div></div><div class="h5">natxo ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
