I see in my controller that the memory utilization for my switch is always around 60% and system load above 25% and shown as yellow. It is still not taking the full load yet, connected to 2 Aruba AP over POE and few other LAN devices. Is that normal?

It is indeed normal. Managed network devices are never truly idle, and unused memory is wasted memory, so you are going to see resource utilization even with nothing connected.
okay… just was worried. Never seen my 10-year-old managed Aruba switch never CPU utilization going above 10% and memory utilization above 20% consistently with lot more load. As long as it is within the parameters I am good.
They are a different vendor with different software and different hardware. You’re going to see different results in that case. As expected, however, it still runs at “idle” with quite a few resources expended.
Either way, unused resources are wasted money. I appreciate your concern, but it would actually be more sensible to watch for over-utilization under load instead. The idle parameters are pretty meaningless unfortunately.
Does that make sense?
Perhaps, to ease end user anxiety, you might consider increasing the percentage before the system load icon changes to yellow? We are kind of trained that yellow means “needs attention”.

I’ve had the same concern with a 16 port and only 5 devices. It’s showing 50%-60% load and 50% memory used. The icon stays yellow, which in most minds means caution.

I agree, if the current thresholds for utilization are fine, the color coding should be adjusted. I’m all for using as many resources as available, because unused ram is wasted ram, as was mentioned, but if 70% (what my 2 ap6 pros sit at) is within the range to be expected it shouldn’t be changing color.

I definitely agree, if the system is sitting idle or hardly being used than there is no need for the actual indicators to show yellow / orange for caution. I can see if the system is actively being hit / heavily utilization… But, idle? That’s honestly another story.
I have used Ubiquiti / Aruba / Mikrotik, and a few other systems and never seen usage stats do similar to how Alta Labs monitors. I honestly had a panic attack when it spiked and I seen it orange until I realized it was just caching / utilizing that much at idle.
I am sitting at 139 kbps on my 8 port, and it’s showing yellow at 37% system load (Randomly spikes to 60%+ ???), and with system memory constantly sitting at 47.5%. Meanwhile, my Route10 is sitting at barely over 1% system usage, with 40% of its memory utilized and it’s currently showing white with approximately 1 mbps running through it.
