Well broken is subjective, the new performance data included the percentage free (as before), with the addition of the actual physical value (ie 1GB). This addition was missing from the RRDs when they were originally created, so when pnp4Nagios was updating the XML file it uses, it said it had 2 data sets, but the RRD only had one. Here’s how I fixed the issue.

Development > Java henrik Sat, 07 Apr 2007 17:03:25 GMT https://rrd4j.dev.java.net/ RRD4J is a 100% pure java implementation of RRDTool's functionality. It follows the same logic and uses the same data sources, archive types and definitions as RRDTool does. RRD4J supports all standard operations on Round Robin Database (RRD) files: CREATE, UPDATE, FETCH, LAST, DUMP, XPORT and GRAPH. RRD4J's API is made for those who are familiar with RRDTool's concepts and logic, but prefer to work with pure java. If you provide the same data to RRDTool and RRD4J, you will get exactly the same results and graphs. RRD4J is made from the scratch and it uses very limited portions of RRDTool's original source code. RRD4J does not use native functions and libraries, has no Runtime.exec() calls and does not require RRDTool to be present. Development > Java henrik Sat, 07 Apr 2007 17:39:26 GMT http://www.vandenbogaerdt.nl/rrdtool/total.php RRDtool stores rates during time intervals. Sometimes you do not want to know the rate (how many bytes per second), you just want to know the total amount of bytes. This can be done, no problem. Please make sure you understand how RRDtool normalizes and consolidates its data. This is explained on my RRDtool - Rates, normalizing and consolidating page. That page already covers most of what you need to know about this subject. You are expected to know its contents in order to understand this page.

RRD is a system to store and display time-series data (network bandwidth, machine-room temperature, mysql queries,dns queries). This page is a good howto for using RRD, all commands listed in one single page.

Detta är inte så knepigt, eller i alla fall inte lika knepigt som att få igång OWFS! Dock är inte RRDtool helt solklart direkt från början, det skiljer sig lite från en traditionell databas.
