Hello,

I’ve been watching this for a while but I notice that Gladys is using almost 12 GB of RAM  
I wanted to know whether this is normal or if there’s a real problem somewhere?

Gladys runs under Docker on my Synology NAS which has 20 GB of RAM.

Thanks in advance 🙂

do you have the problem too then?  
or can you confirm that this isn’t normal 😃

11 GB at my place

But that seems totally disproportionate to me! 😳  
On my machine, it doesn’t exceed 1 GiB of RAM.

@spenceur @VonOx do you have 200,000 devices or users ?  
On va tenter de checker ce qui pourrait provoquer ça.

The `top` or `htop` command lets you view running processes and their resource usage.

I should point out that I only have one camera ^^’

Here’s what it looks like without a camera for me.

You can run `top -b -n 1 -H` and copy all the lines.  
That runs top in batch mode, just once.

I removed the lines related to the camera

Thanks for the command

What bothers me is that this utility seems to display only the virtual memory used.

Let’s try something else. This command installs a more graphical and advanced version of `top` (to be run in your Gladys container).

`apk add -u htop ; htop -s PERCENT_MEM --tree --readonly`

Here’s what it looks like on my system:

 ![Screenshot_20230108-201601](https://gladys-assistant-community.b-cdn.net/uploads/default/original/2X/d/d21bae9b3c8c3aa96a95e72fa90a45e3f99483ea.png)

</div>

I just tested a much clearer command.

1. Connect to the Gladys container
2. Run `node --expose-gc`
3. Paste the following code ([source](https://stackoverflow.com/a/64550489))

```auto
const formatMemoryUsage = (data) =\u003e `${Math.round(data / 1024 / 1024 * 100) / 100} MB`;

const memoryData = process.memoryUsage();

const memoryUsage = {
  rss: `${formatMemoryUsage(memoryData.rss)} -\u003e Resident Set Size - total memory allocated for the process execution`,
  heapTotal: `${formatMemoryUsage(memoryData.heapTotal)} -\u003e total size of the allocated heap`,
  heapUsed: `${formatMemoryUsage(memoryData.heapUsed)} -\u003e actual memory used during the execution`,
  external: `${formatMemoryUsage(memoryData.external)} -\u003e V8 external memory`,
};

console.log(memoryUsage);

```

Result :

Now I’m not sure this takes Gladys processes into account, to be confirmed with your feedback.

Not sure 😃

And for htop

On htop it doesn’t look like your instance is using more RAM than mine. Are you 100% sure that the RAM is being used mostly by Gladys and not by the services on your NAS?

For info, virtual memory has no link to physical memory according to a comment on Node.js’s GitHub.

What you see in the image above is the information from the Gladys container.

Not from the NAS 🙂
