MikroTik – solution to machine running The Dude that hits 100% CPU
Recently I’ve noticed my Dude RouterOS machine that it hits 100% CPU very often and never goes down below 50% CPU.
Now, this is rather beefy machine with powerful two dual core Xeon CPUs and the RouterOS is set to multi-cpu=yes
I went through the settings on The Dude and what I’ve noticed was the default label refresh interval on the map was 1 second.
There’s at least 7 active sessions at any time, all looking at a map with 300+ network devices, all linked (which also show link usage etc).
Immediately after changing that value from 1 second to 1 minute the CPU usage dropped to 1-2% and only occasionally it jumps to 50%.
So if you see similar thing on your Dude monitoring machine try to set the Settings -> Map -> Label Refresh Interval, to something reasonable.
