After using \s-1MRTG\s0 for some time you may find some limitations, mostly in the

Packit |
667938 |
areas of performance and graphing flexibility. These are exactly the areas
|
|
Packit |
667938 |
addressed by RRDtool. To learn more about RRDtool check out its website on

When using mrtg with RRDtool you are replacing \fIrateup\fR with the

667938 |
RRDtool perl module \fIRRDs.pm\fR. To enable RRDtool support in mrtg
|

When you have made this modification to the configuration file, several
|
|
Packit |
667938 |
things will happen when you run mrtg again with the new config file:
|
|
Packit |
667938 |
.IP "1." 4
|
|
Packit |
667938 |
mrtg will take all your old \f(CW\*(C`.log\*(C'\fR files and \fBconvert\fR them to \f(CW\*(C`.rrd\*(C'\fR
|
|
Packit |
667938 |
format. (The \f(CW\*(C`.log\*(C'\fR files don't get touched in the process, so if things
|
|
Packit |
667938 |
don't work out they are still there.)
|
|
Packit |
667938 |
.IP "2." 4
|
|
Packit |
667938 |
mrtg will use \fBrrdtool\fR to update its databases. These will have a new format
|
|
Packit |
667938 |
called \fIrrd\fR which is totally different than the native \fIlog\fR format of
|
|
Packit |
667938 |
the classic mrtg.
|
|
Packit |
667938 |
.IP "3." 4
|
|
Packit |
667938 |
mrtg will \fBnot\fR create any webpages of graphs anymore.
|
|
Packit |
667938 |
It will only query the routers for traffic information and update its \fIrrd\fR
|
|
Packit |
667938 |
databases.
|
|
Packit |
667938 |
.PP
|
|
Packit |
667938 |
The advantage of whole thing is that the mrtg will become \fBmuch\fR
|
|
Packit |
667938 |
faster. Expect the runtime to drop to 20% of the previous value. (I would like
|
|
Packit |
667938 |
to get some feedback on this from folks with large installations.)
|
|
Packit |
667938 |
.PP
|
|
Packit |
667938 |
Mind you, though, while the logging process of RRDtool is \fBvery\fR fast, you
|
|
Packit |
667938 |
are also gaining some time by neither creating graphs nor updating webpages.
|
|
Packit |
667938 |
The idea behind this is that it is more efficient to create
|
|
Packit |
667938 |
graphs and webpages on demand by using a cgi script.
|
|
Packit |
667938 |
.PP
|
|
Packit |
667938 |
At the moment there is no \fBofficial\fR script to do this, but two
|
|
Packit |
667938 |
contributers have created such scripts:
|
|
Packit |
667938 |
.IP "One4All aka 14all.cgi" 4
|
|
Packit |
667938 |
.IX Item "One4All aka 14all.cgi"
|
|
Packit |
667938 |
This was the first program to take over the webpage creation and graphing task.
|
|
Packit |
667938 |
It has been developed by Rainer Bawidamann
|
|
Packit |
667938 |
rainer.bawidamann@web.de. You can find a copy
|
|
Packit |
667938 |
on Rainers website: http://my14all.sourceforge.net/
|
|
Packit |
667938 |
The program comes with its own documentation
|
|
Packit |
667938 |
.IP "\fBrouters2.cgi\fR" 4
|
|
Packit |
667938 |
.IX Item "routers2.cgi"
|
|
Packit |
667938 |
This is another \s-1CGI\s0 frontend for mrtg running with rrdtool. The main difference between this and 14all is
|
|
Packit |
667938 |
that the web pages it creates are much more stylish than the ones from mrtg, plus they support User
|
|
Packit |
667938 |
Defined summary graphs and different levels of Authentication and Authorisation. This has been written by

The mrtg-rrd script is a CGI/FastCGI application by Jan \*(L"Yenya\*(R" Kasprzak for
|
|
Packit |

displaying \s-1MRTG\s0 graphs from data in the RRDtool format. It is an intended
|
|
Packit |

replacement for the 14all.cgi script. It can make your monitoring system
|
|
Packit |

faster because \s-1MRTG\s0 does not have to generate all the \s-1PNG\s0 files with graphs
|
|
Packit |

every 5 minutes or so. Instead of this the graphs are generated on-demand
|
|

when the user wants to see them. http://www.fi.muni.cz/~kas/mrtg\-rrd/
