I am trying to handle rrd Files created by the Nagios monitoring tool.
I am pretty new in this whole topic and i am not sure if this is a dumb question but is there any chance that i can read rrd Files created from Nagios?
Please find attached an example rrd File and the XML file which describes probably the content of the rrd file.
Currently i get the following error when trying to load the file in an RrdDb:
java.io.IOException: Invalid file header. File [/private/tmp/ssh.rrd] is not a RRD4J RRD file
This is obviously true but maybe someone can help me with this topic.
My final goal is to generate a graph for this xml and rrd file.
thx for your support.

rrd files from nagios are comming for rrdtool, and they are not compatible with rrd4j.
You should have a look to:

Hi Fabrice,
thx for your reply.
Now i can open the rrd without an error but i am still "too stupid" to generate the image with this information :-(
I truely don't want to bother you with this probably simple stuff but i am afraid that i do not exactly understand how a rrd file works.
Attached in this post you find a rrd file and a xml description exported from Nagios.
With this info i want to generate a png image file to show it in an web application.
What i do not understand is - do i need the information from the xml file to generate the image or is everything needed to generated an image included in the rrd file?
Maybe you can post a few code snippets how to generate the image in this concrete example?
Thx very much and sorry for my inexperience
kind regards
Stephan
