Hello,
I’m new to using Mikrotik routers. I recently noticed that the CPU load under Resources always shows 0%, even when 30 colleagues are busy working. That wasn’t the case a few days ago. Is there a sensor defective? Where can I start?
Depending on your config it could be most traffic is HW offloaded.
You did not specify model nor the network setup your device is used in ?
Network diagram would help ( can be on paper and scanned in).
Unfortunately I can’t insert a picture here. But in principle it is still a very simple structure. I’ll try to present it like this:
ISP 1: ----> ----------------------------- ----> Panel 1 ----> ~20 PC
I CCR2116-12G-4S+ I
I I
ISP 2 ----> ----------------------------- ----> Panel 2 ----> ~20 PC
During daytime operation, the CPU temperature rises from 38 degrees to ~49 degrees. CPU load still remains at 0%
Might be software related…what RouterOS and firmware version are you running?
MikroTik RouterOS 7.17.2
I installed this today. The previous version also behaved the same.
Your CCR2116 has built in a pretty decent switch chip … which can L3HW offload. And config, necessary for it to happen, is not very different from what we were thought to do for the last few years.
So it’s not entirely impossible that at some certain ROS upgrade your config simply got offloaded to HW … which (if CCR CPU was a bottleneck) means instant performance boost at very notable reduction of CPU load.
Execute this in terminal and check your CPU load then:
:execute {:for a from=1 to=5000 do={:rndstr length=9999}}
ok, i tried.. for 2 seconds the CPU Load ist going up to 3-6%
Then indicator is working fine, you have L3HW offload as @mkx mentioned which doesn’t consume CPU.
That was already mentioned in the very first response too 
Now is confirmed
