Nagios Support Forum

I'm curious how others are displaying their charts, for example bandwidth utilization. I'd love to see my top ten high bandwidth usage server displayed on screen, and/or cycle through the various graphs. If you have a bunch of switches, with over 100+ ports how are you able to view all the charts? You would have to go and click on each one in the GUI? Their has to be a more overall view. Is something like this possible, or possibly already available? I've looked at an application called UCView to point it to Nagios, where I could set a refresh rate on the browser and display some charts this way. But that application isn't working out to well for this idea.

Basically, I want to display the various high usage stats in the NOC on various screens. This will allow for more precise monitoring and viewing of stats.

The biggest issue with this feature would be the relevance of the data. As the bandwidth statistics are saved to an rrd, they already are averaged once you get a week or so out. Once you start adding multiple averaged sources together, you will will have even less clarity in the data. If you are fine with the granularity of the sum of lossy averages, then it may be worth a feature request at http://tracker.nagios.com

I had no idea the data starts to average out as you go further along. I was under the impression you could look at past data and make comparisons, you know build trends. Was bandwidth usage high last month as compared to this month kind of stuff. That's a bummer.

I'm surprised nobody has the need to view data changes in real times, for NOCs and monitoring centers.

The issue with this is then the mode you would use to store the data would be of a monumental size. RRDs are generally quite quick and efficient.
