Node-red-contrib-inspector fail with 32 bits os?

henkkas · 1 October 2022 16:51

Lately I have CPU performance troubles on my RP3B+.
At the beginning of this summer my project was more then 95% finished, and over the summer until now I only made minor changes, some tweaking etc. only more or less of the same functions I already made.
Since a week or so the CPU usage is ramping up over time. Before it was always between 5 and 10%. Now, after restart/reboot, it starts just over 10 and slowly creeps to more then 25% during 24 hours. As long as CPU usage is lower then 10%, Node-Red is performing excellent. Above that performance is getting worse.
With (h)top I can see that node-red is causing more CPU usage.

As I didn't made major changes/developments on node-red, I tried searching for the problem, but didn't find it. So I thought let's try the node-red-contrib-inspector, maybe I can find the source of the problem.with that tool. But now I encounter another problem. It seems I have a 32 bit OS, I always thought I have 64 bits OS.

This is an overview of the software running on my RPI.

Is there somebody that can shine a light on this?

Possibly not helping that you have weird versions of node.js and npm installed. Here's what I have:

Node: v16.17.1
npm: 8.15.0

Generally, you should avoid using odd-numbered versions of node.js as they are considered development versions by many. I think that what you've listed as npm is actually node-red?

Your version of InfluxDB could do with upgrading to v1.8 as well.

I can't read any of the details on that embedded image.

@TotallyInformation Thanks for your reaction. I have replaced the embedded image, It should now be possible to enlarge the image. As about the versions I don't know. At some point in time I installed these with a bash file that was recommended.

bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

As I said before I have not experienced any problems over the summer, until about a week ago.

I am not sure if I can update to higher version without getting new problems.

The versions of NPM and node.js I get with following commands:

If you were able to run the bash command, you can simply run it again but passing --node 16 to get the current LTS version of node.js and the corresponding npm version. You should also do:

cd ~/.node-red 
npm rebuild

after changing major node versions. Makes sure that any C++ libraries are rebuilt correctly.

Then just restart node-red and reload the editor.

To get the actual node and npm versions, this command will do it: node --version && npm --version.

If you are running v2.2.0 of node-red, probably best to get the latest version. The script will do that as well as deal with node.js and npm.

Can't say that this will fix your issue but it may well do so and getting everything current is generally the best starting point anyway. Especially as most people in the forum in a position to help you will be on current versions of everything as well.

How do I do this? I didn't make any C++ applications.

I probably should follow your recommendations, luckily I have a second RPI available so I can test these updates. I will try tomorrow.

TotallyInformation · 1 October 2022 18:49

As I said, this the command npm rebuild in your userDir folder (typically ~/.node-red).

While you didn't make a C++ library, if you have something like the serial or SQLite nodes, they DO have C++ libraries. It is common to get problems after a major version upgrade of node.js if you don't do this.

henkkas · 2 October 2022 12:43

@TotallyInformation, indeed when I give the command npm --version I get result 7.7.6.
I checked the commands again and found the error. I corrected the result and my software version looks like this,

Leaves me the question in my first comment. Why does my RPI 3B+ reports a 32 bits OS when Node-red-contrib-inspector is used with Chrome inspect?

I thought I had 64-bits OS.also to @BartButenaers

henkkas · 2 October 2022 13:27

About testing upgrade node.js 15.x to 16.x, that didn't go well.

Here are the steps I took.

Command: curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash
sudo apt-get install -y node.js
cd ~/.node-red
npm rebuild

At point 4 I got a lot of errors. See this error log

Can you run this from a command line:

node -p "process.arch"

It will tell you whether you are running 32bit (arm) or 64bit (arm64).

Oh, and running this should tell you whether you are running node.js 32bit or 64bit.

file `which node`

I get this on my Debian Intel server:

/usr/bin/node: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), 
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, 
BuildID[sha1]=7dddbc0a9b0312957ec8892bae8b9f98682f82a2, with debug_info, 
not stripped

At this point you should force clear the npm cache with npm cache clean --force.

If you still get errors on rebuild, do the following to delete all of the modules and reinstall them:

cd /home/pi/.node-red
rm -R node_modules
npm install

@TotallyInformation

node -p "process.arch"

Gives me: arm

file `which node

Gives me:

/usr/bin/node: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dyna mically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 4.4.174, wit h debug_info, not stripped

TotallyInformation · 2 October 2022 13:54

OK, that's why you are running 32bit. You have the 32bit version of node.js installed. The 2nd command confirms that.

To run 64bit, you will need a newer version of Rasbian. Not sure if the full 64bit version is out of beta for the Pi 3b+, you would need to check.

I also updated my last post with help for your other error.

Here is the result:

~/.node-red $ rm -R node_modules
pi@pipi:~/.node-red $ npm install

Yup. That worked, no more errors

henkkas · 2 October 2022 14:07

Ohh.... What about 11 vulnerabilities????

I did run npm audit fix

henkkas · 2 October 2022 14:19

When I start flow editor, node-red-contrib-gc gives error on this node.
After removing this node, that I also don't use anymore, It looks fine now.

TotallyInformation · 2 October 2022 14:21

No, please don't do that. We've no idea why the npm/node.js teams thought that was a good idea. In truth, it mostly causes problems because the modules with outdated dependencies may have them for a reason and you can't simply update deep dependencies without potentially breaking things.

henkkas · 2 October 2022 14:23

Ok, very good this is a trial run with a copy of my project.

So I will make a note of that !!
Thanks

henkkas · 2 October 2022 14:32

Hopefully this will fix my problem with cpu load, but I am not sure just yet.
I will run this for a while and check everything, and then maybe tomorrow update the live project.

Thanks so far, I will report results a.s.a.p.

henkkas · 2 October 2022 14:37

@BartButenaers , the Node-red-contrib-inspector cannot work on 32 bits OS? Only 64 bits?

also @TotallyInformation

BartButenaers · 2 October 2022 14:42

Nope I use it both on a 32 bit Raspberry and a full 64 bit Raspberry.
Works fine in both cases for me.
