Hello Heiko,

I use R80.20 and can not found this command:

# iotop -b -n 1

[HeikoAnkenbrand]

Hi Marco,

It is only available on gateway with R80.20 3.10 kernel.

Regards

Heiko

Yes it only work with kernel 3.10.

[Jiangang_Yan]

got a little bit confusing about the answer as "only with 3.10 kernel". Is the release R80.20 with the fixed kernel rollout or the kernel could be changed from Administrator or could be different by different R80.20-Rollout Variation?  

[Valeri_Loukine]

iotop is Linux command, BTW. It is available for newer Linux distributions than 2.6 kernel based

At R80.20 there's a new hack to turn the CoreXL instances on the fly on and off. Here is an example with 3 FW wokers!

Now start the command:

# fw ctl multik stop     -> stop CoreXL instance 1

# fw ctl multik stop    -> stop CoreXL instance 2

# fw ctl multik stop   -> The last instance cannot be disabled:-)

You can activate it again per:

# fw ctl multik start

Conclusion:
CoreXL 0 cannot really be deactivated under R80.10+:-)
