8.203. rrdtool

Updated rrdtool packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The round robin database (RRD) system stores and displays time-series data, such as network bandwidth, machine-room temperature, and server load average. RRDtool is a high performance data logging and graphing utility, which can be easily integrated with shell scripts, or used to create applications using its Perl, Python, Ruby, Lua, Tcl, and PHP bindings. The data is stored in a compact manner that does not expand over time, and RRDtool provides the user with useful graphs by processing the data to enforce a certain data density.

Bug Fix

Prior to this update, the RRDtool utility did not reduce data after the "fetch" operation. Consequently, some data could not be plotted or processed under certain circumstances. With this update, the data is reduced to at least the chart resolution after the "fetch" operation, and all the data is now plotted or processed as expected in the described scenario.
Users of rrdtool are advised to upgrade to these updated packages, which fix this bug.
