[sake...@gmail.com]

Hello,
I'm trying to use java melody as monitoring in my application,with aspect of security we are not able to use the Jrobin jar instead can i use other rrd tools available.

I tried it replacing the jrobin with rrd4.jar ,but it throws RRDException as below

Any other RRD tool compatible with javamelody to display the graphs or any option to configure external RRD tool apart from jrobin.

Please suggest.

Hi sakeeachu,

javamelody is written to work with jrobin 1.5.9.

It can't work with rrd4j (or any other). Rrd4j is a fork of jrobin but rrd4j classes are not binary compatible with jrobin classes.

bye,

What is the fix for this ?

Hi,

You probably need to include the jrobin jar file as a dependency in your webapp:

https://repo1.maven.org/maven2/org/jrobin/jrobin/1.5.9/jrobin-1.5.9.jar

This is done automatically when using maven and one of the javamelody dependency.

bye,
