This is caused by a fundamental limitation of how the counters are updated on these platforms, you just need to use large enough interval times that their slow counter updates aren't visible.

JunOS isn't Linux, it's FreeBSD, quite famously so too. Ironically, a FreeBSD-based platform is where the realtime graphing code is borrowed from.

The best that would be possible would be for us to keep polling until the counter changes, and only plot a point when the counter changes, but I'm not really sure how well that would work, and since the underlying code is borrowed from the m0n0wall platform from 15 years ago, so I have a feeling it would need to be completely rewritten now.

Hi Guys,

I have noticed that the real-time graphs for devices that run Linux natively (JunosOS, UnifiOS, etc) display the traffic with "intervals in between".

The non-native Linux devices (FortiOS, Cisco IOS) provide a nicer real-time graph for port traffic when polled.

Is there something that could be adjusted so that the native Linux devices show the nicer graph?
