Evok high CPU usage
-
Hello,
i've tried using Evok on my Neuron but after each reboot the CPU usage for /usr/bin/python /opt/evok/evok.py keeps at or areound 100% (as shown by htop) at all times. I don't consider this normal ... or is it ?service evok statusreports that evok is active.
/var/log/evok is completely empty ... so; I guess the question is if CPU (one of the cores) usage of 100% is by design or is there something I can check to see what's happening ?

This does seem very odd. It's possible that EVOK would use up a single core entirely under heavy use - it has minor multithreading, but it's built on the Tornado webserver, which unlike django et al. is primarily single-threaded - but it shouldn't be at all times.
Could you please describe which Neuron unit you have, in what way you are using EVOK and which (if any) changes you have made to the system? This is merely a precautionary measure, as we have had e.g. customers connecting foreign SPI devices to our bus, and then being surprised by the system malfunctioning due to conflicts.
As for debugging info - if you can run EVOK manually (i.e. python /opt/evok/evok.py; needs root privileges) and paste the output here, that would be great help; normally only exceptions are logged (you can change this in the /etc/evok.conf file). Other things that could help us would be the output from

I'll have access to the device later in the day and I'll post the requested data at the time.
For now I have the following information:
-Neuron S103
-nothing is explicitly connected to or using EVOK yet. The CPU usage occurs either immediately after power up if EVOK is enabled as a service, otherwise if I disable the service (systemctl disable evok) and start it manually (systemctl start evok), the same thing happens, so it is completely reprodcible on my system
-nothing other that a power supply is connected to the Neuron
-Open source OS was loaded from your repository
-installed software (all in the initial post-install blank state, no running projects, CPU sits at ~0% idle when EVOK is disabled)
Pixel desktop with LightDM login manager
Codesys runtime (started but without any projet)
node.js
Node-red (not started, just installed)
Leafpad text editor
Geany programmer editorNeuron is connected to active Network, RealVNC is running and SSH is enabled.
In short, I installed some basic software that I need (and know from using Raspbian), no projects yet. I planned on using EVOK to access Neuron's I/Os and other optional devices in the future.
I do remember that there was an error reported during the installation of EVOK (in the python installation code), however I've re-downloaded it (the "master" branch, as instructed) and re-installed it three times with the same result - everything seems to have been installed nevertheless. I'll try to get the installation log if it's possibly relevant.
I haven't tried running it with "python /opt/evok/evok.py" yet - will do (is it any different that systemctl start evok ?)

I managed to get the CPU usage down...port 8080 which is used by default by EVOK is also used by default by Codesys WebVisu.
I reinstalled Evok using ports 85 (instead of 80) and 8085 instead of 8080.
Although the CPU usage went down immediately after this, evok still doesn't work.
Further testing:

Looking at the evok log, now I also have the same error as displayed when running the script manually (as above).
-
The port issue is probably due to NGINX; the port conflict would cause EVOK to restart continually which causes the CPU spikes.
As for the infinite loop - it looks like EVOK can't communicate with the hardware over SPI. Along with the port issues it's probably the most common problem encountered with EVOK, as the I2C/SPI driver setup is somewhat delicate in comparison with the software itself.
Could you post your /boot/config.txt as well? It's likely that you have both dtoverlay=neuron-spi-new and dtoverlay=neuron-spi; if so please delete the former. This can be caused by reinstalling EVOK master on the open-source image, as the open source image already includes a customised version, which is not fully driver-compatible with the github one.
-
I don't see a dtoverlay=neuron-spi line, there are however a couple of duplicate lines in /boot/config.txt

I apologize for pushing this issue again, but it's been a week since any updates and evok is still not working here. If there are any suggestions how to proceed (based on the data provided), pleas let me know.
I appreciate any help.

@tempurpri
Please try to delete the dtoverlay=neuron-spi-new line, this should hopefully fix your issue.The GitHub master distribution has been updated to stop EVOK from restarting if it fails to start several times in the row. But the issue lies here in the fact that EVOK fails to start (which, as it is necessary for the device to function, it tries repeatedly), rather than the restarting itself.
As you correctly observed this was originally caused by the port conflict with your NodeJS installation (or perhaps some other server, as only a single server can ever be connected to a port on standard TCP/IP architecture).
If this does not help, you may have to install pigpio
sudo apt-get install pigpioas well. Or perhaps a better option might be to try and redo the installation process from scratch, using the EVOK version designed for the more comprehensive device drivers in the open-source image - not the version on GitHub.
-
In the end, nothing else than starting from scratch with a fresh image of the open-source OS helped.
Then I was able to change the evok port to 8085 (instead of 8080) and nginx port to 85 (instead of 80) prior to installing codesys and it worked.

for a while. I started a new separate thread since the problems have a little bit different symptoms.
