Hi ,

I am executing check_jvm.sh plugin in our tomcat server as root user. But it throw below error,

"UNKNOWN JVM is running with different username, run this script with UID 1011"

I couldnot get the output.

Please do the needful.

Thanks,

You can search the /etc/passwd file on that server for the UID to see what username it is expecting.
Run this as root to get the username

Code: Select all

grep 1011 /etc/passwd

Then you would have to change the owner of the script using that username found from the above command using this example.

Code: Select all

chown username check_jvm.sh

Try that and see if it fixes the issue.

Hi ,
I tried above one. I got same error.

tomcat1011:301::/home/tomcat:/bin/bash
-rwxrwxrwx 1 tomcat nagios 6580 May 18 16:03 check_jvm.sh

[root@sesklshrddev01 plugins]# ./check_jvm.sh -n Tomcat_BioHazardDev -p heap -w 80 -c 90
UNKNOWN JVM is running with different username, run this script with UID 1011
Please help me

One thing I found in the documentation for the plugin, you need to use sudo to run it as the tomcat user which will make it match the service running as the tomcat user as well.
You would have to edit the command defined in nagios like the example below which will run the plugin as the tomcat user.

Code: Select all

/usr/bin/sudo -u tomcat /usr/local/nagios/libexec/check_jvm.sh -n Tomcat_BioHazardDev -p heap -w 80 -c 90

Try that and if you have any questions, let us know.

Hi,

I cannot run from nagios server ( Remote server)

Can you help me.

[tgriep]

If you are using the NRPE agent to run the check on the remote system, you would have to edit the /etc/sudoers file on the remote server and add the following entry

Code: Select all

nagios    ALL=(ALL) NOPASSWD: /usr/local/nagios/libexec/check_jvm.sh

Then the command that is defined in the nrpe.cfg file would look like the example below.

Code: Select all

command[tomcat_heap]=/usr/bin/sudo -u tomcat /usr/local/nagios/libexec/check_jvm.sh -n Tomcat_BioHazardDev -p heap -w 80 -c 90

Then restart the NRPE Agent and see if this fixes the issue for you.

Take a look at the README file for that plugin at this link.
