1 Round Robin Database Tools
2 ==========================
4 It is pretty easy to gather status information from all sorts of things,
5 ranging from the temperature in your office to the number of octets which
6 have passed through the FDDI interface of your router. But it is not so
7 trivial to store this data in a efficient and systematic manner. This is
8 where RRDtool kicks in. It lets you log and analyze the data you gather from
9 all kinds of data-sources (DS). The data analysis part of RRDtool is based
10 on the ability to quickly generate graphical representations of the data
11 values collected over a definable time period.
17 check out the instructions in doc/rrdbuild.txt
22 Either after compiling or after installing you can try the example
23 RRDtool applications in the examples directory.
28 Read the documentation in the doc directory. Start of with
29 RRDtool. All documents are available as html and as ASCII text.
31 If you are looking for a more slow paced introduction, make sure to read
32 Alex van den Bogaerdt's rrdtutorial which is also available from the doc
33 directory. Also read his cdeftutorial and Steve Rader's rpntutorial.
35 If you want to know about the format of the log files check
36 src/rrd_format.h there are a lot of comments in there ...
