I will try to keep a long story short. It all started with the following patron with routeros v6.7
In Green the uptime the other colors are the load of each core.
(notice at first I only monitored the first core add mid-march the other cores)
Conclusion, the system gets busier when the uptimes gets higher.
Let’s look at the traffic patrons during that time.
Not the same patron, doesn’t grow and goes low again like the cpu load.
If I magnify the memory use vs uptime I get this during that time
Same like cpu load. I know its not a lot of memory difference and no issue, but it seems linked to the issue.
To solve the issue I tried some more v6 version:
Strange things, I want to understand why the cpu load rises and the traffic stays the same. A downgrade to v5.26 show the old trends I always say. Currently I will let it run v5.26 until v6.13 is out.
Long term trend view…
The router is running about 8 bgp peers, 2 ospf peers, 300k bgp routes, 50 ospf routes, no conntrack, x86, 20 forward firewall rules.
I can’t help that I think something is going wrong. I understand that v5 and v6 report a different value for the same traffic but it should be linked to the load / use and should not build up when the uptime becomes more. The problem is not really an issue since the router can handle the load.
I have had routertable corrupting in v5.xx and thats why i want to run v6..
I will try keep you all informed how things go. Any tips are more welcome.
