Node-red-contrib-vcgencmd : reset throttling statistics

[BartButenaers]

Hi folks,

I received I very good question from one of the forum members, but I don't know the answer myself so I post it here. For privacy reasons - and since he is still 'trying to learn' - I won't mention his name here

Summarized it is about my node-red-contrib-vcgencmd, which allows a.o. to determine whether the Raspberry:

• Is being throttled currently (e.g. due to thermal overheating or under voltage by bad power supply)
• Has been throttled since the last reboot

But it would be nice if we could know whether the Raspberry has been throttled since a specified moment in time, instead of since the last reboot.

Seems to me that there are not much options:

• Reset messages would be the best solution, since you can decide yourself when the statistics should be reset. But by reading this discussion I conclude that you CANNOT reset it?
• Suppose you just look at the 'current' throttling state every N seconds, then you don't know if throttling happened in between (i.e. in the last N seconds).
• Running the vcgencmd every second seems overkill to me...

If anybody has a creative proposal, please let me know and I implement it in my node...

Thanks !

This is a flow I have bashed together.

There is work needed because of the mentioned problem with the "flag" (memory) outputs.

Extra nodes needed:
traffic
gate (yeah, traffic was used as well. I should get rid of traffic)
queue
fan handy to keep flows neater
ring-buffer used to show list on dashboard
string to format stuff

The fan node can be ignored and just wire past it.
The gate and traffic nodes are needed only for enabling the flow, and controlling what is shown.

Top left of the flow with the LINK node. (The top one)
This basically is the input / clock (if you will) to activate the flow.

There is three parts to the flow.
Top, middle and bottom.
The middle has three parts too.
Left, middle, right.

Walk through:
Top:
This receives the clock input and generates the command/node.
It then filters the message and queues up what is received. (Optional)

Middle:

Left part - starts building the message to be displayed. Sets up button to wipe the list on the
dashboard. Also displays messages on Dashboard.
Another list is queued in a queue node for edit screen viewing.

Middle - allows timed control of how long the outputs are logged to a file.

Right - Saves outputs to a file.

Bottom:
This shows graphically the state of things.
At the bottom you will see the new part to be applied to all of the latter 4 outputs because of the above mentioned problem.

To simulate an error, allow the flow to establish itself then stop it. (top left of the top part)
In the bottom part there is an inject node marked TEST.
Press it and look at the dashboard.
You will see a simulated alarm.
Between the two sets of buttons, you can see a button which is now enabled.
Clicking it, it will wipe the notification.
Re-enable the flow and after a cycle, all should return to normal.

Pictures to save typing too many words.

Pic 1:
All good.

Pic 2:
TEST button pressed.
Really the "undervoltage" text would remain.
Note the enabled button in the middle.

Pic 3:
The ACK button pressed

Then it will loop back to Pic 1 when you re-enable the flow.

[Trying_to_learn]

Here is a bit of a re-write of the bottom section of the flow.

Works a bit better.

It needs the text to be better modified so it shows it as a FLAG (appended to the existing text)

@BartButenaers

But by reading this discussion I conclude that you CANNOT reset it?

Found here somebody that claims it should be possible, by adding a bitmask parameter to the command:

vcgencmd get_throttled 0x7

I understand this from his explanation:

• There are two persistent values stored in the Raspberry:
  • Value A: Keep track whether the Raspberry has been throttled since reboot.
  • Value B: Keep track whether the Raspberry has been since the bitmask has been used.
• You can get hold of both of these values:
  • Get value A by calling the command without bitmask.
  • Get value B by calling the command with bitmask.

If it works like this, then I think I should implement it in my node like this:

• Add a checkbox in my config screen "reset throttling status at every measurement".
• Apply the bitmask when the checkbox is selected.
• Add a warning in my readme file that only a single node-red-contrib-vcgencmd node is allowed to have this option. Indeed there is only 1 value B available in your Raspberry so the nodes would start resetting each others value B ...

Is there anybody that could check whether this theory is valid?
Not sure how I could 'easily' throttle my Raspberry temporarily to experiment with this.

The only "problem" is how to test it works as claimed.

My latest flow gets around that problem.

Mine is currently throttled due to having a temporary HDD attached - lowering the supply voltage.
How can I help?

Indeed.
Could use the cpuburn program (as described here), but it sounds a bit to desctructive to me

Hey Paul,

After reading yet another discussion, I think we are heading in the right direction. Seems the two values are called 'sticky bits':

• value A is called the 'permanent' sticky bit (= since the last reboot)
• value B is called the 'recent' sticky bit (= since the last reset)

From that discussion it also seems that you can (based on the value of the extra argument):

• Read AND reset the 'recent' sticky bits.
• Only read the 'recent' sticky bits.

We first need to figure out which extra argument we need to add to trigger those two commands.
[EDIT 8/9/2019] I have submitted my question in that same discussion. Hopefully I get an answer soon ...

Afterwards we could try to test it like this:

1. Throttle your system
2. Read the 'recent' sticky bits: this should show that throttling has happened.
3. Reset the 'recent' sticky bits
4. Read the 'recent' sticky bit again: this shouldn't show anymore that throttling has happened!!!!
5. Throttle your system again
6. Read the 'recent' sticky bits: this should show again that throttling has happened.

Does this test make sense?

Would be nice if we could use this to implement 'reset messages' in our node. Then you could determine by yourself during which interval you want to determine whether throttling has occured.

My time is up for today. See you tomorrow guys!

I've been doing more work on this flow.

I'm a sucker for geeky looking things and so have added another button and changed the layout.

As was the RBE/ALL button would either let one different messages through, or ALL.

The WIPE button would wipe the visible list.

If you want to see an uptodate list, it is not nice having to toggle the RBE/ALL to All then back to RBE when the screen updated.

I added a LET ONE MESSAGE THROUGH button. And! It is animated when pressed!
That is because it can take some time for the flow to get a trigger pulse to run the command.

So it looks like this:

(Yeah, I know. I gotta get a life.)
