<div>Yes. Rrdtool scales much greater than rateup.</div>

Which benefits will I have using it or not ?</p>
</div>
</div>
</blockquote>
</span>
<div>Greater granularity (up to millisecond precision if you were to poll that often) as opposed to fixed at 5 minute polling cycle.</div>
<div>Support for negative numbers (for example, temperature sensors or dB meters)</div>
<div>Faster update times - just updating a database that is designed to consolidate daily/weekly/monthly/yearly views rather than fiddling with flat files that take a long time to parse and rewrite.</div>
<div>Less up-front processing. Rateup creates a graph on every polling cycle. Rrdtool just updates the data and lets you create the graphs at time of view, leading to much lower cpu utilization.</div>
<div>More flexible graphs - rrdtool gives you almost limitless formatting capabilities and combined metrics, while rateup just creates one style of graph.</div>

I need an external database or could be embedded ?<br>
</p>
</div>
</div>
</blockquote>
</span>
<div>Not for rateup. You may want one if you are tracking 100’s of switches. Large sites generally set up mrtg configs for each switch as a separate file, and then include them all from a master mrtg.cfg file that just contains include statements from all
of the switches. </div>
<div><br>
</div>
<div>For example, I have about 700 devices, all with unique snmp credentials. I have a database that lists the credentials, as well as which template should be applied to each device. I have a script that will check to see which devices are reachable, create
a mrtg.cfg file with all of those config files included, and also put together a script to run mkconfig for a subset of the devices that are being managed.</div>

<p dir="ltr">We don't need to monitor these servers the number I sent.<br>
We need to follow the network elements(switches and routers) behaviour . We have approximately 100 of this . I couldn't sent this number before because I didn't have it.<br>
I have to know an idea of the server I need, to ask here <br>
Tks</p>

When I asked, the person could tell me how many switches was out, but I can ask this tomorrow.<br>
Any other question will be answered if necessary.<br>
Thanks,</p>

<div>2500 Red Hat boxes or 2500 switches? Do you mean analyze or just poll traffic data? Please describe your environment and exactly what you want to analyze more thoroughly.<br>
