ntopng pro: constant, high CPU usage #640

Closed beveradb closed 4 years ago

beveradb commented 8 years ago

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.

2016-07-04 01_16_46-greenshot

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!

lucaderi commented 8 years ago

As you have not specified an interface with -i, noting listens to all interfaces including loopback. Please add with -i an interface to listen to, and report what happens.

ftoniolo commented 7 years ago

Hi, lucaderi! I'm having the same issue (xenserver virtual machine with very high load average when using ntopng during some hours). After reading your comment, I tried to start capturing only from eth0. Unfortunately, the result was the same: high load. What could I try? By now I'm using the old version (ntop) and it works fine without the high load, but the new version features and interface are much better. Thank you!

simonemainardi commented 7 years ago

@ftoniolo make sure to upgrade and use the latest dev build as we have made some fixes recently.

ftoniolo commented 7 years ago

Hi!

I updated the ntop package just now (there was a new version available). After few minutes running the updated version, ntopng increased the load average again to more than 6 :( There is another thing that could I do?

Thanks!

@andrewthecoder show the output of ntopng --version

also you should add a -i to your config to specify the monitored interfaces of interest

try with version dev 2.5.x

how many interfaces are you monitoring? what's their speed and load? How many active hosts/flows you have on average?

ftoniolo commented 7 years ago

Ok, I'll try the recommended version. I'm starting it with the -i eth0 option.

I don't know how to obtain the '2.5 dev' version, because I'm using the centos' yum package manager.

simonemainardi commented 7 years ago

you should add the repos at http://packages.ntop.org/centos/

ftoniolo commented 7 years ago

Hi!

OK, I updated to recommended version as below:

[root@firewall ~]# ntopng --version v.2.5.161014 [Enterprise/Professional Edition] GIT rev: dev:4c14311a1d90d9807190a3b8d09ed29dc6a46711:20161014 Pro rev: r698 System Id: D8EC8AC99206A1D8 Built on: CentOS release 6.8 (Final)

During the weekend, load average remained low and stable. Today morning, it jumped to about 6 again.

I have 5 network interfaces in this vm: eth0 (lan) eth1 (dedicated link 2Mbps full duplex) eth2 (dedicated link 1Mbps full duplex) eth3 (adsl link for navigation, 15Mbps down, 768Kbps up) eth4 (dedicated link 10Mbps full duplex) - this is a new link, configured last week - the problem of high load average was already accurring before installing it

I'm capturing eth0 only in an attempt to reduce the load.

simonemainardi commented 7 years ago

uhm, ntopng supports speeds much greater than those you have described.

Can you please comment on the VM hardware resources allocated (CPU and RAM?). Note that each monitored interface translates into an independent thread so you should make sure your multi-core/multi-CPU system is able to properly handle that.

ftoniolo commented 7 years ago

Sure! Please, see the attached screenshots describing the basic vm and xenserver host configuration.

simonemainardi commented 7 years ago

so the load looks ok its 0.03.

Report the statistics when you experience an high load as reported. By the way I would increase the RAM allocated for the vm.

ftoniolo commented 7 years ago

Yes, the load avg is low because I'm using the old version (ntop). I made that htop's screenshot just for showing you an overview of my hardware like cpu, memory and i/o usage (not for show the load avg).

If you think that it is important, I could change to the new version (ntopng). After some time, probably my load would be increased. So I could capture a screenshot for the purpose of showing you the high load avg.

Thanks

Hello,

I've got the same issue on my platform : ntopng --version v.3.9.190221 [Enterprise/Professional build] GIT rev: dev:a486d2c19fc7226f9b247f3051b1d6b55268beb7:20190221 Pro rev: r2259 Built on: Ubuntu 16.04.5 LTS Platform: x86_64 Edition: Enterprise License Type: Permanent Maintenance: Until Tue Nov 12 14:42:47 2019 [264 days left]

Here is my configuration file :

-n=3 -w=8000 -W=0 -g=31 -m="50.176.0.0/16,50.177.0.0/16,50.178.0.0/16" -X=800000 -x=80000 -d=/storage/ntopng -G=/var/run/ntopng.pid -i=eno50

My ntopng's core 31 (i'm using affinity) is very high

Can you help me ?

Best Regards,

emanuele-f commented 5 years ago

Does the high usage occurs during normal operation or when a browser window on the ntopng gui is opened? Please also post the output of top -H -p $(pgrep ntopng)

Can you attach gdb to the top threads, one at a time, and post here the results? For example, in order to attach to the first top thread (pid 1953):

sudo gdb `which ntopng`
attach 1953
bt
exit

post the output of the "bt" command above per each top thread

Can you attach gdb to the top threads, one at a time, and post here the results? For example, in order to attach to the first top thread (pid 1953):

sudo gdb which ntopng

attach 1953

bt

exit

post the output of the "bt" command above per each top thread

emanuele-f commented 5 years ago

so you've dumped the stack of the following threads:

1953 ntopng 20 0 4422508 2,903g 62028 R 96,7 1,2 17:42.75 ntopng
1954 ntopng 20 0 4422508 2,903g 62028 R 96,7 1,2 13:17.55 ntopng
1986 ntopng 20 0 4422508 2,903g 62028 R 96,0 1,2 4:18.20 TrPoolWorker

everything seems normal (the first two processes are the one serving the gui timeseries charts requests). What is the stack trace of 1992 ?

daxrob commented 4 years ago

I just installed the latest version of ntopng on a small HP server: RAM 2GB CPU 2 core AMD Turion II Neo N40L 64 bit Windows 7 Pro 64 bit

I monitor a 30Mbps link, so I do not expect a lot of traffic. Despite that, ntopng is always at 80/90% of CPU.

I restricted the service to a single interface and I added those parameters in the service following your tuning guide: -n 1 -m 192.168.1.0/24 -x 8000 -X 8000 --capture-direction 1 --community --ignore-vlans

Nothing changed. Could you suggest if I can change some parameter in order to reduce the CPU utilization?

Thanks.

simonemainardi commented 4 years ago

-x/-X 8000 is a small number. Increase it significantly as it must be much greater than the actual number of hosts.

Then please report new behavior and ntopng version.

daxrob commented 4 years ago

Increased to 20000. The CPU it is still between 40-90% all the time. Now I have around 3 to 7 Mbps of traffic. 476 flows. 96 hosts (inside + outside of my network). 2020-05-27_140554

simonemainardi commented 4 years ago

ntopng version?

daxrob commented 4 years ago

ntopng Community Edition v.4.1.200428

simonemainardi commented 4 years ago

Please, update as you need a more recent version which contains https://github.com/ntop/ntopng/commit/607ba52263830c577e7b37c8c25320e60466a5f6

daxrob commented 4 years ago

The version I have is the most recent available on your website: http://packages.ntop.org/ http://packages.ntop.org/Windows/ntopng-4.1.200428-x64.zip

simonemainardi commented 4 years ago

@lucaderi can you please refresh the Windows build to make sure it contains the high-cpu fix?

daxrob commented 4 years ago

Thanks Simone and Luca, so I should see the new version with the fix on this link? http://packages.ntop.org/

simonemainardi commented 4 years ago

correct

daxrob commented 4 years ago

I tried to download the new version that should include the fix, but the version available is still the same: v.4.1.200428

simonemainardi commented 4 years ago

@lucaderi will notify you once the new windows build is ready

lucaderi commented 4 years ago

Package released with fixes. ntopng 4.1.200609

daxrob commented 4 years ago

Thanks Luca. I think you have to fix the download link on http://packages.ntop.org/.

simonemainardi commented 4 years ago

Download links are OK: http://packages.ntop.org/Windows/

daxrob commented 4 years ago

I just go to http://packages.ntop.org/, then clicked on "Windows", then clicked on ntopng. It show me a "Not Found" page. I am sure the direct link will work.. It is the "ntopng" link that have to be fix.

2020-06-10_092230 2020-06-10_092222

daxrob commented 4 years ago

By the way. The fix didn't fix the problem. See the attached processor graph.

2020-06-10_104616

simonemainardi commented 4 years ago

here's the direct link: make sure you are running this version: http://packages.ntop.org/Windows/ntopng-4.1.200609-x64.zip

daxrob commented 4 years ago

Yes, I already installed that version on top of the old one: ntopng Community Edition v.4.1.200609

lucaderi commented 4 years ago

The image you attached is not reporting any issue. I don't understand whereas the problem here. Can you please elaborate? The previous version was constantly over 100% that is not the cat here. Not to say that is hard to comment without knowing anything about your traffic. I will close this issue unless you have good arguments against this

lucaderi commented 4 years ago

Closing this ticket. Will reopen is necessary. We believe the behaviour reported is correct

daxrob commented 2 years ago

Hi,

I just upgraded to v.5.1.210907 (Windows). The ntopng.exe process is consuming around 80-95% of CPU constantly even if there is no traffic. Only broadcast.
