Nagios Support Forum

I am having issues with the commands.cfg file and JAVA_ABS_PATH. I tried creating /etc/sysconfig/Nagios file and restarting Nagios to set the following environment variables.

export JAVA_HOME=/opt/ds/java/jdk1.8.0_162
export JRE_HOME=/opt/ds/java/jdk1.8.0_162/jre
export JAVA_ABS_PATH=/opt/ds/java/jdk1.8.0_162/bin/java
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH

I don't want to put commands.cfg in static as i want to be able to update it thru the web interface.

The following command fails when JAVA_ABS_PATH is not set. (No output on stdout) stderr: execvp(JAVA_ABS_PATH, ...) failed. errno is 2: No such file or directory)

define command {
command_name check_xi_java_as
command_line JAVA_ABS_PATH -Djava.class.path=$ARG2$:$USER1$/check_jvm.jar GenericASCheck $ARG1$
}

If I change the command like the following it works fine in the Web Interface.

define command {
command_name check_xi_java_as
command_line /opt/ds/java/jdk1.8.0_162/bin/java -Djava.class.path=$ARG2$:$USER1$/check_jvm.jar GenericASCheck $ARG1$
}

Is there any method to get commands.cfg to pick up variables so this is not overwritten every time when you apply configuration in the web interface? /etc/sysconfig/Nagios doesn't seem to work.
Thanks for any response.

Hello @rwbata,

You can set your own variables using macros, and use those in you check commands. See the guide below.
