The JNRPE addon is a Java replacement of NRPE and is designed to allow you to execute Nagios plugins on remote machines. Differently from NRPE, JNRPE gives you the ability to execute plugins written using the Java language without the overhead of many short lived JVM instances (NRPE executes the plugins as external executables: that means that to execute a Java plugin, one JVM must be started for each java-written plugin execution).
The main reason for using JNRPE is to allow Nagios to monitor “local” resources on remote machines with ‘write once, run everywhere’ plugins. Moreover, JNRPE itself is a Java application, so it can run on all the operating systems where Java runs removing the limit to Unix/Linux.
The Nagios plugins will be executing as follows:
There are several places to obtain support for JNRPE. They are presented here in the order in which you should probably consult them.
The documentation is the source of informations about JNRPE.
The tutorials is where you can find the solution to common tasks.
The Help Forum is the place where you can ask for help to the community
