Interface monitoring

bbeachy2001

I have a question about the graphs when I'm monitoring an interface. Below is an example. This is the interface on at Cisco 9300 that is receiving all my internet traffic from my Palo Alto firewall.

The radial gauges stay steady and accurate. The Real Time Data chart, however, constantly bounces up and down and don't depict the steady traffic flow, which is what I'd like to see. I also know that it says the Polling Interval for the interface is 120 seconds, which of course is not real time.

Are there any adjustments I can make to make this show me real time statistics, with a smooth chart showing bandwidth being used? I'd like to eventually put this on my main dashboard, and it would be nice if it was smoother...

Thanks.

So what you have on that chart is a bunch of polled values, I think the default is 2 seconds. The spike are the only data that it has, and the graph doesn't "smooth" because when you need that level of detail you might want to know when polling is missed. It only grabs polling data that frequently while the page is loaded. If you added those value to a perfstack, I think you can 'turn on' real time data while looking at it and it will smooth the line, I don't know that real time is an option for the widget you would put on the dashboard.

This KB article may also apply here. PerfStack real-time polling for interface utilization shows incorrect values and spikes in Orion Platform (solarwinds.com) What may be happening is that the real-time polled data is not synchronized with how often the Palo Alto is updating their OID statistic. You may need to update the RealTimePollRate to match.
