High CPU usage ntopng Package - even on idle?

ramup

@Rai80: Thanks for sharing your experience. Due to my change in system setup, can you tell me how high the average CPU idle was with notpng under 2.4.3?

I had (have) the same problem with not instantly starting or later exiting notpng services from the beginning on. I installed watchdog so it restarts the process automatically when it exits due to an error.

On 2.4.3 is was about 2-5%. And with high traffic and webinterface open it was around 15-20%. After closing the webinterface it dropped to 10-15%.
So it seems much more CPU intensive after 2.4.4. and much less stable.

Hope there will be an update soon!

OK, are there any other users who can confirm this behaviour with high CPU usage of ntopng in IDLE mode? If yes, I would issue a bug in redmine.pfsense.org to examine this behaviour.

Btw. I can`t say that ntopng is less stable under 2.4.4 but since I use watchdog I do not check anymore how often the process exits. But the problem occured already under 2.4.3 and before and as far as I read this happens under FreeBSD regularly so I live with it because it is not really an issue when watchdog restarts the process immediately.

But the hig CPU usage is more a problem that I can`t really estimate (in comparison to 2.4.3) especially since my change of hardware with 2.4.4. Before I used XEON vCPUs and as they are more powerful the CPU usage was not an issue because the server was under a certain load anyway.

i had the same issue with ntopng on a virtualized server
cpu usage went up to 60% on an i5-6200u cpu

deleted the package and the cpu usage went back to 5-8%

@Jack150 Did you install ntopng under 2.4.4 or in a previous version?
Did 60% occur during idle or load? Were you monitoring while that high CPU usage?

Jack150

I did install ntopng under 2.4.3 but shortly after the upgrade to 2.4.4 i got the issue.
it happend on idle and i was only watching @ system activity

i just did a reinstall of ntopng, it was running fine
but after i added another port to my bridge the cpu when back up

see screenshot of system activity:

Now in 2.4.4-p1 I reinstalled NTOPNG, and CPU usage has dropped and stays much more stable (low).
So seems to be fixed.

I'm using the latest nightly build of ntopng pro and finding it's using a large amount of CPU time constantly, even when the user interface isn't open in a web browser, and even when there's barely any traffic passing through the server.

My configuration file contains:

-G=/var/run/ntopng.pid
--disable-login=1
-F "mysql;localhost;ntopng;flows;username;password"
-w=3050

However the same still occurs even if I remove the mysql line (I suspected it was file IO of writing flows, but apparently now).

Any suggestions to track down what ntopng is doing would be greatly appreciated - the load average on the server I'm running it on is through the roof!
