Nagios Support Forum

I download the check_tomcat.sh script from the url
https://exchange.nagios.org/directory/P ... ap/details

Then I put the check_tomcat.sh script into on my nagios server , the path I put is /usr/local/nagios/libexec
then I run the script use this command:
[root@VSLHAGILEAP01 libexec]# ./check_tomcat.sh -j Boot -w 80 -c 90
The error is
[root@VSLHAGILEAP01 libexec]# ./check_tomcat.sh -j Boot -w 80 -c 90
sudo: unknown user: user
sudo: unable to initialize policy plugin
cat: /proc//status: No such file or directory
CRITICAL: process pid[] Tomcat Service Not Running

I install nagios server on 192.168.75.10 , the os is Cent os 6.4
The tomcat I install is on 192.168.75.11, the os is Windows 2003 server
I want to monitor the tomcat on the 192.168.75.11
How could I configure the check_tomcat ?

Whether this script can monitor the tomcat report the error "java.lang.out of memory" ?
If it can monitor ,please tell me the method ,thanks very much!

This script is a bash script and hence it needs to be execute on a linux server.

The script is designed to be run on the server that has tomcat installed, hence running it on your Nagios box is not going to work.

On your windows server, where are you seeing the error "java.lang.out of memory" ?

The Tomcat windows report error:"java.lang.out of memory"
I want to use Nagios monitor the error , Please tell me the method.

Perhaps provide a screenshot to show us exactly where the error is occurring.

The tomcat report error:
java.lang.OutOfMemoryError: Java heap space

A screenshot would really help, it lets us see where you are seeing the message.

The picture show the tomcat out of memory

Which scipt should I use can monitor the out of memory ?

You could try using JMX:
