Will enabling the Traffic Connections for the Smartview Monitor blade have an affect on CPU and memory resources? If so, what is the impact?
I think it doesn't affect on performance. Maybe very little impact for management server resource.
It is only shows resource usage.
Had someone ask me the exact same question in a private email after reading my book, here is their original question and my answer:
>Regarding using the Monitoring Blade for "streamlined firewall performance troubleshooting". Do you recommend to enable all 3 check boxes (CP system counters, traffic connections and traffic throughput)? A note in the configuration page says "traffic history reports may have performance implications". Are there any recommendations to avoid those? > Yep definitely enable all these. What this actually does is load a separate kernel driver on the firewall called rtm to gather and record the extra statistics. Perhaps in the old days prior to CoreXL and the speedy cores/memory we enjoy now, the performance impact would be noticeable. I haven't noticed any kind of performance/acceleration degradation by enabling all these checkboxes for many many years, and I
think this ominous-sounding warning is just legacy now.
