Unbound DNS report setting error & CPU usage is too high

[MAENESA]

I use the version

Code: [Select]

OPNsense 23.7.6-amd64
FreeBSD 13.2-RELEASE-p3
OpenSSL 1.1.1w 11 Sep 20231.I turned off Enable local statistics collection in the unbound dns report and saved it. Just jump to the white page and display:

I turned off intrusion detection and reporting in the traffic settings local capture,The CPU usage has been reduced, and this problem has not occurred before with the same settings.

I tried Reset Netflow Data and Reset RRD Date, everything seems to be normal, I don't know if there is any connection between them.

I'm a bit unclear what your issue is with Unbound Reporting.  What do you mean by "white page"?

Some people have had Unbound Reporting get corrupted.  Clicking on Reset DNS Data will often fix it.

What are you using to get what you posted for the CPU issue?  You didn't post the headers and they don't match top or the OPNSense UI.

Sorry, my English is not very good, so I use machine translation to ask questions。
2.1 I try to close Reporting: NetFlow Capture local Options, CPU usage is reduced from 6ghz to 300mhz.
2.2 Check CPU usage of applications. I use the

Code: [Select]

ps -aux | head.

[CJ]

No problem.  What is your native language?  There may be a few people on here that speak it.  There's also the International section if it's one of those.

I don't recall NetFlow being particularly CPU intensive but it's been a while since I did anything with it.

ps aux | head is not a good method to search for high CPU utilization.  If you look at the snippet you posted, your machine is showing as idle.  A better way is to look at System -> Diagnostics -> Activity or ssh in and run top.
